«ROSTOK» Corn is a liquid, highly concentrated, chelated microfertilizer which meets the needs of the crop.

The composition of fertilizer elements is selected to provide plants with the necessary nutrients in critical phases, and to quickly correct their deficiency.

Used for seed treatment and foliar feeding of corn, sorghum.

The fertilizer contains macro nutrients, trace elements, amino acids, carboxylic acids, humic substances and an adhesive.


- increases the viability of seeds;

- stimulates the growth and development of plants;

- strengthens the root system and increases the utilization rate of nutrients from soil and fertilizers;

- contributes to the additional provision of plants with nutrients;

- improves the growth of vegetative mass;

- increases the resistance of plants to diseases;

- increases the resistance of plants to unfavorable soil and climatic conditions;

- improves the grain content of the ears and increases the mass of grains;

- increases productivity up to 25%;

- improves the quality indicators of grain.

It is also recommended to add «ROSTOK» Extra, «ROSTOK» Grain, «ROSTOK» Macro and «ROSTOK» Zinc to improve plant growth and development.

Предпосевная обработка семян: проводится в 5-30% водном растворе продолжительностью до 4 часов (в зависимости от культуры).

Внекорневая подкормка:

Порядок приготовления рабочего раствора:

1. Резервуар опрыскивателя наполнить на 2/3 объема водой, добавить карбамид (при необходимости), включить мешалку;

2. Добавить по очереди макро- затем микроудобрения «УАРОСТОК»® и препараты защиты растений (если они предусмотрены и рекомендованы, после их предварительного смешивания и опробования);

3. Дополнить резервуар водой до полного объема и приступить к опрыскиванию.


Of using complex fertilizer on complex-forming acid basis (EDTA) 

«ROSTOK» Corn 


Form: liquid.

Purpose: - seed treatment,

                 - foliar feeding.

Composition:  Macronutrient, micronutrient,  humic substances - 5 g/l, amino acids  - 0,4%, carboxylic acids, sticky substance.


Content of active substances, g/l























Approach of using and consumption rate:

Seed treatment: either (soaking) is performed in 5-10% aqueous solution of micronutrients for up to 4 hours (depending on culture). The prepared solution can be used several times within 24 hours. After processing the dried seeds must be sown immediately.

 Foliar feeding: in this way elements are absorbed from fertilizers by plants at 95-100%. Consumption rate of working solution is 200-300 l/ha.

The value of fertilizers «ROSTOK» Maize: a universal fertilizer composition that meets the biological needs of corn. Among cereals, maize has the highest removal rate and assimilation of trace elements from soil. The formation of 1 ton of grain and vegetative appropriate quantity of corn from 1 ha of soil, kg / hectare: N - 20-30, P2O5 - 8-10, K2O - 15-17, and a lot of calcium, magnesium (Mg) - 6 -10, sulfur (S) - 4-5, manganese (Mn) - 0,15, zinc (Zn) - 0,05-0,1, boron (B) - 0,01-0,02, molybdenum (Mo ) - 0.01, iron (Fe) - 0,2 and other trace elements. Traditionally this culture consider  as "indicator" of trace elements in the soil. Corn is sensitive to their application, particularly zinc (Zn), manganese (Mn), copper (Cu) and boron (B). For lack of which inhibited plant growth and development, reduces productivity of the culture.

Zinc (Zn) is involved in nitrogen metabolism, promotes the synthesis of the amino acid tryptophan, which acts as a regulator of plant growth. Zinc is also a part of enzyme systems that regulate carbohydrate, fat, phosphorus metabolism and biosynthesis of vitamins. The use of high doses of phosphate and potash, lime fertilizer, low soil temperature, sealing its low content of organic matter, high phosphorus (P), calcium (Ca), magnesium (Mg) or copper (Cu) it reduces the availability of zinc for plants. Manganese (Mn) improves assimilation of mineral nitrogen compounds, activates processes of respiration, photosynthesis and root growth. Sandy soils (light grain size), high content of organic matter, high content of iron (Fe), copper (Cu) and zinc (Zn) in the soil reduces the availability of manganese to plants. Copper (Cu) increases plant resistance to low temperatures, especially in the early phases, as well as drought and heat resistance of plants. Copper regulates carbohydrate and protein metabolism. The use of high doses of nitrogen, lime fertilizers and high nitrogen (N), phosphorus (P) and zinc (Zn) lowers plants ability to gain copper. Boron (B) promotes the growth of meristem tissue of vegetative and root system of plants, germination of pollen in the pollen tubes increases its fertility, improving processes fruiting and increases the yield of corn. Dry conditions, high content of nitrogen (N), calcium compounds (Ca) and potassium (K) in the soil reduces the availability of boron to plants.

The use of fertilizers "ROSTOK" Corn helps:

• improve the vitality of seeds;

• stimulate plant growth and development;

• strengthening the root system and improve the utilization of batteries from the soil and fertilizers;

• additional protection of plant nutrients;

• active rise of vegetative mass;

• strengthening plant resistance to disease;

• increase plant resistance to adverse soil and climatic conditions;

• improving the ears and mass of 1000 grains;

• improve the chemical composition of the grains;

• Increased productivity of the culture by 10-15%.

General recommendations: it is expedient to prepare tank mixtures of urea and crop protection liquids (if necessary). Foliar feeding of plants is better to perform before 12 th hour of the day or after 17 o'clock in the evening during the phases of growth and development of crops that are most sensitive to the provision of micronutrients.

Corn plants has two critical phase regarding to the provision of micronutrients:

1) 3-4 leaves phase - formed the first tier of secondary root system that only under favourable soil conditions, able to consume the micronutrients. In this phase, to stimulate the growth of nodal roots is important to ensure plants besides has phosphorus, also manganese (Mn), zinc (Zn) and boron (B). At the same time, forming a layered mechanism, which also requires ensuringof optimum quantity of manganese (Mn), zinc (Zn) and copper (Cu).

2) phase of 6-8 leaves - rapidly developing secondary root system of the plants ,begin to form elements ofgenerative organs (fork) and an intense growth of leaf surface. In this phase, increasing the need for micronutrients: zinc (Zn), manganese (Mn), boron (B) and copper (Cu).

Not recommended for handling during the day when it is scorching sun or windy weather. Evening or morning dew on the efficiency of feed is not affected! The water temperature for preparation of the working solution should be close to the ambient temperature (not recommended to perform the processing with cold water,dialed directly from the well, as is the likelihood of stress in plants, which contributes to the development of disease, cessation of plant growth and their death).
