Seedling master. Italian Master is a new generation fertilizer. What is suitable for

Application of Valagro masters for different plants

1) Tanks A and B are filled 1/3 with water.
2) A small part (10-20%) of the calculated amount of acid is added to the water (nitric acid can be added to any tank, orthophosphoric and sulfuric acids - only to tanks A or C (if you want to have a mother liquor with magnesium in a separate tank).
The optimal pH value of the mother solutions of complex fertilizers is 4.
3) The calculated amount of fertilizer is added to the tanks and thoroughly mixed. Tank A we fill up the master and, if necessary, magnesium sulfate. The amount of fertilizer you need can be calculated using the NPK calculator. Pour calcium nitrate into tank B.
4) Add water to the required amount (usually tanks for mother liquor have a concentration of 100 times more than the ready solution for irrigation)

Tanks must be protected from direct sun rays. Keep in mind, Valagro masters have different solubility. The lowest solubility in the master 10.18.32 - 15 g per 1 liter and the highest in the master 20.20.20 - 55 g per 1 liter

THE CONCENTRATION OF THE MOTHER SOLUTION SHOULD NOT EXCEED:

10% solution when using potassium sulfate, monopotassium phosphate;
-20% (200 kg / 1000 l of solution) when using MASTER, potassium nitrate, calcium, magnesium.

It is impossible to mix calcium nitrate (calcium nitrate) and those containing sulfur and phosphorus (magnesium sulfate, potassium sulfate, monopotassium phosphate, monoammonium phosphate) in the same tank.

If concentration is used instead of units of weight nutrients in water (for example, 0.01% solution), then required amount fertilizer is calculated by dividing the concentration by the percentage of the given substance in the fertilizer.

Example: To obtain a 0.01% nitrogen concentration using MASTER 15.5.30, it is necessary to dilute 670 g of this fertilizer in 1 cubic meter (1000 l) of water. Remember that this amount of MASTER will give 0.003% P2O5 and 0.02% K2O.

In common terminology, the content of N, P, K is written from left to right and is expressed as pure nitrogen N, phosphoric anhydride P2O5, potassium oxide K2O as a percentage.

Example: Fertilizer MASTER 15.5.30 contains 15% nitrogen, 5% phosphorus oxide, 30% potassium oxide. In terms of weight, 1 kg of such a fertilizer contains 150 g of pure nitrogen N, 50 g of P2O5 and 300 g of K2O, or, in other words, 22 g of pure phosphorus (P) and 249 g of pure potassium (K).

UNITS CONVERSION TABLE

1. When using preparations for the preparation of tank mixtures, it is necessary to take into account the possibility of the influence of the pH of the reaction of fertilizers on the stability of the solution containing plant protection products. Valagro fertilizers are generally acidic and are highly compatible with most pesticides.

2. On initial stages plants need available phosphorus, zinc and boron, therefore, top dressing with such preparations as MASTER 13.40.13 is recommended.

3. Fertilizers with a high content of potassium - MASTER 20.20.20, 15.5.30+2, 3.11.38+4- are mainly used at the end of the growing season to improve product quality (keeping quality, sugar level, taste).

4. The amount of solution must be sufficient to wet the entire leaf mass of the treated crop.

5. An important role is played by the electrical conductivity of the solution EC. A solution with a high concentration of salts can cause irreparable damage to the plant. As a rule, for most plants, an acceptable level of electrical conductivity of the nutrient solution is 1.5-3.5 mSi/cm.

6. Monitor the temperature of the working solution. Since the process of dissolving fertilizers is accompanied by the absorption of energy, the temperature of the solution can drop sharply. The critical value is 10°C.

Everyone knows that when fertilizers are applied, it increases the yield of plants. But after all, there are many top dressings on the market now. How to decide and not get confused when choosing one that will really effectively serve the benefit of plants and their owners?

You need to choose from dressings from well-established manufacturers. One of these is Master fertilizer - this is a product Italian company Valagro.

Characteristics and effect of Master fertilizer on plants

The nutritional complex contains trace elements in the form of chelates. They are highly soluble in water and have increased efficiency. This top dressing is produced in various proportions of nitrogen, phosphorus and potassium, because different concentrations of these elements are needed at different periods of growth. Therefore, before applying Master fertilizer, you should always read the instructions first.

It is used during the active development of the plant, by drip irrigation or sprinkling (fertigation) and foliar application. The nutrient complex is suitable for perennial and annual flowers, indoor plants, seedlings, vegetables, berries, grapes. After applying the fertilizer Master garden and horticultural crops get:

• more saturated color leaves;
• better survival in a new place;
• harvest ripening ahead of schedule, thanks to active vegetation;
• increased resistance to diseases;
• greater productivity.

Plant development often exceeds the expectations of their owners with this supplement, so there are many positive feedback about fertilizer Master.

This nutrient complex is characterized by:

From a technical point of view, this top dressing is ideal for foliar fertilizers: it does not remain undissolved on plants, does not litter the sprayer, and is compatible with other products.

Fertilizer composition

The nutrient complex contains macronutrients such as nitrogen, phosphorus and potassium. Each of listed components plays important role during the growing season, and ultimately affects the size of the harvested crop.

1. Nitrogen is an important component of nucleic and amino acids, proteins. When it is not enough in the soil, the amount of green pigments decreases: the plant becomes pale, light green, its growth slows down.
2. Phosphorus - is also present in the composition of crops. It is especially needed for young plants, because it accelerates the growth of roots, it has a good effect on fruit set, as well as their ripening. Flaw given element negatively affects the beginning of the growing season and the digestibility of nutrients is disturbed.
3. Potassium is a component that is found in plant cells. Enhances the intensity of metabolic processes and cell reproduction. It also stimulates photosynthesis and synthesizes sugars. Lack entails violations of the activity of enzymes, protein and carbon metabolism, and the productivity of crops decreases.

As already noted, some types of Master fertilizer have the same composition, but differ in concentration, and sometimes in different ratios of key components.

There are also trace elements such as iron (Fe), manganese (Mn), copper (Cu), boron (B), zinc (Zn). They are contained in the form of chelates, which means that they dissolve easily in water and are well absorbed by plants.

Usage Tips:

2. Conifers, deciduous ornamental trees and bushes are fed in spring, and at the beginning of summer with an interval of half a month.
3. Strawberries are fertilized from transplanting young plants to the start of berry setting.
4. Cabbage receives a nutrient complex after planting seedlings before leaf formation.
5. Cucumbers are fed from the beginning of growth until 5-10 leaves grow in them.
6. Tomatoes are fed in a week from the beginning of growth in a new, already permanent, place, and until flowering.

Fertilizer Master-color Orchid

This top dressing enhances the bookmark of flower stalks. You can not give a nutrient complex when the plant is at rest or after planting in a different pot, also if the flower is not healthy.

Also, do not use the Master Orchid during flowering, so that the plant does not accidentally drop flowers.

Instructions for using fertilizer Master-color

The use of Master fertilizer has a positive effect on the condition of not only plants, but also the soil, as it fills it with nutrients and contributes to enrichment. Since the elements are contained in the form of chelates, the effect of applying top dressing is 10 times stronger than that of similar fertilizers.

It is used for watering in dissolved form. Root systems of crops absorb nutrients. This nutrient complex is suitable for any type of soil. Fertilizer Master is manufactured according to accepted quality standards.

In order for the soil to accept mineral artificial fertilizer, the company added phosphate from Belgium, potassium nitrate and a sulfate compound to the composition of monopotassium. Other similar manufacturers European countries Chinese monoammonium phosphate is used.

A few "don'ts" when growing tomatoes, fertilizers for tomatoes

Fertilizers for tomatoes can be made independently, or you can buy ready-made ones. The main thing in the subcortex of tomatoes is the choice of the right fertilizer for tomatoes: in no case do not over-fertilize them with manure, chicken manure, mineral nitrogen fertilizers, you need to give phosphorus-potassium fertilizers, ash and potassium sulfate.

When growing tomatoes, several factors must be taken into account, or rather, remember some “don’ts”:

You can’t grow plants in oily, overly fertilized soil with organic matter; - you can’t put bird droppings and manure in the holes for tomatoes, because because of them the plants will go into greenery, and not into fruits; - you can’t fertilize tomatoes with mullein more than three times a season; - you can not put urea under the plants, you can only sprinkle once at the beginning of the growing season; - you can not plant different varieties tomatoes nearby, it is better to choose one and grow it, you should also not plant plants in the shade and too densely; - you can’t fill the tomatoes with water, this will interfere with the supply of oxygen to the roots; - you can’t plant tomatoes at soil level, planting on high beds will be better; - you can’t change fertilizers. It is necessary to opt for one complex mineral fertilizer and use it together with organic matter in a strictly defined amount.

And always consider the characteristics of the soil before buying fertilizer. It is better to carry out the 1st top dressing in early June, one liter of fertilizer mixture should be added under each bush (add 1/2 liter of mullein, a tablespoon of nitrophoska, two tablets of micronutrient fertilizers and 1/2 teaspoon to ten liters of water). boric acid).

The 2nd top dressing is advisable at the beginning of July, applying a liter of the fertilizer mixture made under each bush (add 1/2 liter of mullein, a tablespoon of potassium sulfate and 2 tablets of micronutrient fertilizers to 10 liters of water). After the second half of July, top dressing of tomatoes should be stopped.

Fertilizers Valagro

The quantity and quality of agricultural products grown depends on many parameters. One of the most important factors affecting the growth and development of plants is mineral nutrition. Together with photosynthesis, it constitutes a single process of metabolism between the plant and the environment. The minerals needed by plants are divided into three groups:

• Macronutrients- nitrogen ( N), phosphorus ( R) and potassium ( To);Mesoelements- sulfur ( S), calcium ( Sa) and magnesium ( Mg);trace elements- iron( Fe), manganese ( Mn), zinc ( Zn), boron ( AT), molybdenum ( Mo) and cobalt( So).

The introduction of modern water-soluble fertilizers and growth regulators can be carried out by fertigation and foliar application (foliar application). Fertigation is an irrigation method in which water is supplied to the root zone of plants through a system of pipelines and micro-outlets (emitters).

The main feature of drip irrigation is the supply of water directly to each plant in accordance with its needs. Due to this, application rates are reduced by 3-4 times mineral fertilizers, which are supplied together with water directly to the root zone.

In fertigation systems, control of optimal concentrations of fertilizers, their ratio is easily achieved, and these parameters can be controlled automatically. The set and sequence of fertilizer application is calculated according to the seasonal needs of the plant. The rates of applied fertilizers depend on many factors and are determined by their planned removal. Parameters that affect the absorption of nutrients from the soil by the root system:

• Crop variety and phase of its development; Soil moisture; Temperature environment and illumination; Soil structure; Interaction of ions (antagonism and synergy); Content of organic matter in the soil.

During drip irrigation, water does not fall on the leaves, therefore, the plant is less susceptible to diseases, the likelihood sunburn completely missing. Users of drip irrigation systems benefit in terms of product maturation. Foliar top dressing provides a quick replenishment of the plant with macro- and microelements.

This need arises in cases where plants have a particularly high need for nutrients at certain stages of growth and in critical situations, or in cases where root system cannot use soil nutrients. This may be due to an unbalanced supply of nutrients, with unfavorable weather conditions, unsatisfactory soil pH or when the soil is highly compacted, waterlogged or cold.

The rate of absorption of various nutrients in the plant under normal natural conditions (foliar application with water-soluble fertilizers)

The rate of absorption of trace elements depends on the form of the complexing agent (salt, EDTA, DTRA, LSA, LPCA, etc.) and averages 1-2 days. Iron as a microelement is more effective to apply to the root zone.

Tomato is a very useful culture, but also demanding to grow. The first fertilizers for tomatoes begin to be applied to the soil long before they are planted, in the autumn months, so that the earth becomes fertile and saturated with all the necessary substances. Fertilizers should be chosen with a low nitrogen content in relation to other components. Planting is carried out in the spring, and the soil should be ready with autumn is important rule, which every gardener needs to remember. Today we will tell you exactly what fertilizers are needed for a crop such as a tomato, according to what scheme they are applied and what should not be used for tomatoes.

Types of fertilizers for tomatoes

You can fertilize tomatoes various formulations which consist of the following components:

1. Superphosphate is the most common and effective fertilizer for tomatoes and is best suited. It contains nitrogen, magnesium, calcium, sulfur, phosphorus. This fertilizer helps to reduce the acidity of the soil. In addition, magnesium contributes to the rapid development of nightshade crops. Superphosphate is available in the form of dry granules and powder, which are diluted in water along with other products. Usually a garden sprayer is used for application. Complex fertilizers are a prepared mixture that includes potassium, phosphorus, nitrogen. This is nitroammofoska, which is one of the best for top dressing. Manure is used for tomatoes, wood ash, humus, peat.

Mineral fertilizers are applied once every two weeks, for this they use root and foliar top dressing, additives in wells, spraying. Peat-humic mixtures with sodium humate and a strain of Bacillus subtilis are used.

Tomato feeding scheme

Many experts say that fertilizers for tomatoes can be very different, the main thing is to strictly follow the dosage and the scheme for their application. What and how best to feed them? Let's take an example general scheme fertilizing when growing in any conditions (for poor soils and with rainy summer the amount should be doubled, but the dosage should be reduced by one third). Tomatoes love top dressing and respond best to phosphorus-potassium fertilizers, which also increase the quality of the fruit (low nitrate content), and regulate their simultaneous ripening.

1. It is necessary to feed when planting seedlings. Application time - after 15 days. Nitrophoska, complex fertilizers are added to the soil. Dosage: for 1 liter of water - half a teaspoon. 10 days after the first dose and then every 10 days, nitrophoska and a solution of potassium permanganate are added. The solution is very weak, half a teaspoon is added to it complex fertilizer per liter of water. Superphosphate and potassium sulfate are added 15 days after picking. Dosage: one tablespoon of each component per 10 liters of water. You can additionally add 2 tbsp. spoons of Kemira. Fertilizers for tomatoes can also be applied to the wells. This is superphosphate, saltpeter with the following dosage: for each well, a tablespoon of top dressing. After 7-10 days after planting, all plants are watered with a weak solution of potassium permanganate. After 10-15 days, ammonium nitrate is applied, which is applied at a dosage of 10-20 g per 10 l water. To get early harvest, it is necessary to use foliar top dressing every six days from a mixture of urea, superphosphate and potassium sulfate. For every 10 l, 10-15 g / 10 g / 10-15 g are added, respectively. At the time when the first brushes begin to bloom, tomatoes need a solution of azofoska and mullein, which are applied at 25 g per 10 l of water. The rest 2-3 main feedings are carried out at intervals of two weeks. To do this, take mullein, potassium sulfate (mullein can be replaced with bird droppings). A mixture such as potassium sulfate and ammonium nitrate is also suitable. The dosage is 30 g per 10 liters of water at the rate of 15 g of mullein and 20 g of potassium sulfate (or 25 g ammonium nitrate and 30 g of potassium sulfate).

How to fertilize tomatoes

Tomato is a crop that takes out a lot of nutrients from the soil. This is said to normal growth plants is possible only with the introduction of such as phosphorus, nitrogen, and also potash.

They must be applied both during and during the main application. Let us dwell in this article on what fertilizers are needed for tomatoes, and more specifically on the need to apply mineral fertilizers to the soil for tomatoes and some trace elements.

Fertilizer. Plant nutrition

Fertilizers for tomatoes

Let's look at nitrogen first. It is required by plants for rapid growth for the synthesis of amino acids and proteins. If too much nitrogen is applied, there will be a delay in fruit ripening.

plant resistance to disease and low temperatures decreases. When using unbalanced nitrogen supplements, tomato fruits accumulate nitrites and nitrates. Potassium is a nutrient and is removed by the plant from the soil.

It retains water in cells, participates in the biosynthesis of carbohydrates and proteins, and also promotes the movement of substances from vegetative organs to generative ones. Also, thanks to potassium, the plant becomes more resistant to diseases and low temperatures.

Despite the fact that the tomato does not take much phosphorus out of the soil, it reacts very well to the application of phosphorus fertilizers. The main thing is that the tomatoes do not feel their lack. Thanks to phosphorus, cell division is enhanced.

First of all, it is very important for young immature plants. They are very good at extracting phosphorus from the soil.

The presence of phosphorus in sufficient quantities throughout the growing season contributes to a better emergence of ovaries and ensure better growth fruits. As well as with potassium, phosphorus has a positive effect on the resistance of the plant to diseases and low temperatures.

From the foregoing, it is clear that what fertilizer is needed for tomatoes. Now we need to consider what the lack of certain fertilizers affects.

What threatens the lack of fertilizers

What kind of fertilizers for tomatoes, or rather, nutrients in the soil for plants, is not enough, can be judged by the appearance of the plants, albeit approximately, but still. With a lack of nitrogen, plant growth slows down. This can be seen in the lower leaves.

At first they turn pale, and then die off completely. The same will happen with other leaves. If nitrogen is in excess, then the leaves of the plant will be dark green in color, large, growth is quite fast. The lack of phosphorus is reflected in the growth of tomatoes.

The leaves are just getting smaller. The color of the leaves and stem becomes reddish purple. The lack of potassium can be judged by the lower leaves.

They first turn brown, then die. The same fate eventually awaits the upstream leaves.

How to fertilize tomatoes - trace elements

In addition to the above fertilizers, tomatoes need trace elements. Depending on what microelements are lacking in the nutrition of the plant, the yield may decrease, growth may decrease, etc.

In the case of sandy soils, as well as peat soils, they usually lack zinc, copper, and calcium. On peat, sod-gley and sod-podzolic - boron. On weakly alkaline soils, chernozems, there is usually a lack of manganese.

To provide young plants at the first stage of growth with microelements, seeds can be soaked in a solution of microelements. As for the growing season, microelements are applied directly to the soil during the main fertilization, as well as during the fertilizing period.

Because the tomatoes photophilous plant, then for them you need to choose well-lit areas, while it is desirable that they have a slope towards the south or south-west. If a shadow falls on the plants, then this will negatively affect the yield.

When growing tomatoes in a greenhouse, you need to choose a design in such a way that there are as few different shading elements as possible. This applies in particular to the roof. If you are growing this culture under the film, then you need to take care of its cleanliness in a timely manner. Perhaps this is the main thing that should be said about.

Fertilizers for tomatoes

Tomatoes are less responsive to direct application organic fertilizers, how late cabbage, and are best placed in areas where organic fertilizers have been applied to the previous crop. If there are organic fertilizers on the farm, 2-3 kg of manure or compost and 60-70 g / m3 are brought in for autumn digging? nitroammofoski or a mixture of ammonium nitrate, superphosphate and potassium chloride.

Tomatoes are the most demanding for phosphorus nutrition vegetable crop, although it removes phosphorus from the soil many times less than nitrogen and potassium. From the moment of seed germination, phosphorus contributes to enhanced root growth, earlier flowering, accelerated fruit ripening, increased yield, increased sugar content and dry matter in fruits.

In addition, for normal fruiting great importance has potassium. At the same time, the effect of phosphorus-potassium nutrition on the acceleration of fruit ripening is manifested only with a sufficient supply of nitrogen to plants, preferably in the ammonia form. Nitrogen-potassium nutrition is especially necessary for plants during budding, flowering, fruit formation and until the end of fruiting.

The lack of nitrogen, and even more so potassium, weakens the growth of plants, leads to crushing of fruits and a decrease in yield. However, an excess of nitrogen, especially during the period of vegetative growth, contributes to the "fatting" of plants, a significant delay in the onset of fruiting and an increase in their susceptibility to diseases. It has been established that 94% of the phosphorus absorbed by plants goes to the formation of fruits.

From each kilogram of powdered superphosphate containing 180 g phosphoric acid, plants take only 30-50 g, the rest goes into a form inaccessible to them. The introduction of granular superphosphate leads to better absorption of phosphorus and to a lower cost of fertilizers (2-4 times).

Young plants, in contrast to adults, due to an underdeveloped root system, are characterized by a weak ability to absorb sparingly soluble phosphorus compounds. The use of granulated superphosphate in the wells when planting seedlings (10-12 g) accelerates fruiting and increases yield by 10%.

Between fertilizers and plant roots there should be a soil layer of 2-3 cm. Excess chlorine is harmful to tomatoes, so potash fertilizers for this crop are best applied in the form of potassium sulfate. However, even with a lack of chlorine, chlorosis is observed - the leaves turn brown and curl, root growth stops, fruiting is delayed. Tomatoes are responsive to foliar top dressing with microelements.

So, boron stimulates the germination of pollen, having a positive effect on the processes of fertilization, setting and growth of fruits. With a lack of it, growth points die off along with the buds.

Manganese increases assimilation carbon dioxide, promotes absorption nitrate nitrogen and better education fruits. With a lack of its buds fall off. Copper improves carbohydrate and protein metabolism, increases the intensity of respiration.

The lack of it, as well as magnesium, is sometimes observed on sandy soils when growing early varieties. The effect of foliar top dressing with boron-manganese fertilizers is effective. For tomatoes, not only the lack of individual nutrients is harmful, but also their excess.

So, an excess of nitrogen or phosphorus can lead to a lack of potassium, and an excess of potassium can lead to a lack of magnesium or calcium. The need for magnesium increases with the introduction of potassium chloride on light soils.

Liming the soil increases the need for plants in potash fertilizers, but at the same time, the availability of boron and manganese to plants decreases. In order to obtain high yield tomatoes to grow good seedlings. If the plants are stunted and have a pale color, then it is good to feed them with mullein (1:8) or bird droppings (1:10).

15 g of ammonium nitrate and 10 g of potassium sulfate are added to a bucket of such a solution. A glass of it is spent on two plants. After 8-10 days, top dressing is repeated, a glass of solution is already spent on one plant.

The next top dressing is carried out after 10-15 days with a fertilizer mixture - 50 g per bucket of water or 15 g of ammonium nitrate and potassium chloride and 20 g of superphosphate are dissolved in the same amount of water. A few days before planting, 1.5-2.0 g of dry granular superphosphate is added to the soil for each plant, then fresh soil is added and watered well. To prevent diseases, plants are watered with a solution of potassium permanganate - 5 g per 10 l of water.

Such watering after the seedlings take root is carried out weekly, first spending half a glass of solution for two plants, and before planting - a glass for each plant. Top dressing is carried out after planting seedlings in the ground.

At the same time, ammonium nitrate 4-5 g, superphosphate 16-20 g and potassium chloride 3-4 g / m are added before fruiting. , during the period of mass fruiting - ammonium nitrate 8-10 g and superphosphate 14-15 g / m?. It is better to use fertilizers in solution during irrigation. However, their more rapid effect on the growth and development of plants is observed with foliar top dressing.

In addition, the effectiveness of such dressings is less dependent on meteorological conditions. They can give good results in spring, when the soil is not yet warmed up, and the air temperature is already quite high. The concentration of ammonium nitrate solution for foliar top dressing after planting tomato seedlings in the ground should not exceed 0.4% (40 g per 10 l of water), in the flowering phase - 0, 6-0.7% (60-70 g per 10 l of water), fruiting - 0.8-0.9%) (80-90 g per 10 l of water).

Most effective action foliar top dressing is observed when combined with root top dressing - fertilization in the wells. According to studies, the increase in tomato yield in the first two weeks of fruit harvesting was 17% with root feeding, 12% with foliar feeding, and 48% with a combination of root feeding with foliar feeding. Foliar feeding with microfertilizers also accelerate fruit ripening.

For example, spraying plants with a solution of boric acid (10 g per 10 liters of water) during the period of mass flowering gives approximately the same effect as treating them with growth stimulants. Foliar top dressing it is best done in the evening, as at this time the nutrient solution applied to the leaves dries slowly, and the morning dew, in addition, helps to absorb the nutrient solution remaining on the upper surface of the leaves.
