Nutrivant plus corn, Odessa region.

NUTRIVANT PLUS CORN water-soluble fertilizer withadhesive Fertivant for foliar top dressing of corn. Manufacturer: "ICL Fertilizers", Israel.

Formula: 6N-37P2O5-5.4K2О+4.8Mg+3.4Zn+Fertivant (FV).

Packaging: 25 kg.

Physical condition: solid crystalline powder.

Action: Составудобрения программы corresponds to the physiology of mineral nutrition of corn culture. Due to the special "Fertivant" adhesive, the fertilizer is not washed away by sediments from the surface of the plant leaf.

Easily available phosphorus compounds at the early stages of corn organogenesis activate the growth and development of its root system and contribute to the establishment of a high yield. Zinc takes part in nitrogen exchange, activates the synthesis of the amino acid tryptophan and the phytohormone auxin. Zinc is also involved in carbohydrate, fat, and phosphorus metabolism, the synthesis of chlorophyll, vitamins B, P, and C and increases the resistance of corn to frost.

The critical phases in corn are 3-5 and 6-8 leaves - to throw out the panicles.

Application and doses: foliar top dressing.

in the phase of 3-5 leaves - 2 kg / ha and in the phase of 6-8 leaves with a dose of 3 kg / ha.

The volume of the working solution for foliar fertilization should be at least 200-250 l/ha.

Researches of the Institute of Grain Management of the National Academy of Sciences, Dnipropetrovsk, 2009. it was established that two-time foliar feeding of grain corn "Nutrivantom Plus™ corn" at the rate of 5 kg/ha ensured an increase in its yield of 8.7 tons/ha against the control of 47.8 tons/ha, which was not processed. "Nutrivant Plus™ corn" also increased the protein content to 7.9% and starch to 74.3%, when the control protein content was only 7.0% and starch was 71.8%.

According to the data of the German scientist D. Shpaar, at a corn yield of 6 t/ha and at a humidity of 14%, this amount of biogenic elements is carried out.

Note

Before starting foliar foliar spraying of "Nutrivant Plus™ corn", it is not necessary to dissolve it in a separate container and prepare the mother solution (with the exception of aerial processing).

Procedure for preparing the working solution:

Fill the sprayer capacity with water to 3/4 of the total volume;
Turn on the agitator of the sprayer;
Pour "Nutrivant Plus™ corn" into the container of the sprayer;
Add to working solutionplant protection products;
If necessary, pour urea;
Fill the container with water to the full volume, prepare a homogeneous working solution and start foliar top dressing.
It is not recommended to use "Nutrivant Plus™ corn" in the same working solution with pesticides, the composition of which includes metals - iron (Fe), aluminum (Al) and with concentrated solutions of calcium (Ca).
"Nutrivant Plus™ corn" can be mixed with potassium nitrate (KNO3), potassium sulfate (K2SO4) and urea (CO (NH2) 2).
It is not recommended to use a nozzle with coarse spraying (only with medium and fine) for foliar foliar feeding of plants with "Nutrivant Plus™ corn".
It is recommended to dissolve "Nutrivant Plus™ corn" at a water temperature of 20 degrees C, but not lower than 10 degrees C.
Before using "Nutrivanta Plus™ corn", it is necessary to carry out preliminary testing for the absence of sediment when mixing with pesticides or other drugs, as well as for the absence of plant burns.
Due to the "Fertivant" adhesive, the fertilizer is not washed away by sediments from the leaf surface of plants.
In the spring-summer period, it is recommended to carry out foliar top dressing at an air temperature of no higher than 25 degrees C, since at high temperatures the water of the working solution evaporates quickly, which leads to an increase in the concentration of salts on the surface of the leaves and can cause plant burns. The best foliar feeding of "Nutrivantom Plus™ corn" is carried out in the evening or early in the morning.
