TOPERS is a new water-soluble mineral complex fertilizer produced from organic substances of natural origin by electrolytic dissociation and ionization of the basic solution. Basic solution of TOPERS is a concentrate which contains water soluble nitrogen compounds in the form of ammonium nitrate, carbamide, phosphorus – mono- substituted phosphoric acid residue and potassium, calcium, magnesium, sulfur and microelements in ionic form. The working solution has proved its effectiveness by experience and laboratory researches, and it is recommended for use as the basic fertilizer for the fields, gardens, greenhouses and smallholdings. The concentration of nutrients in the basic solution is bioecological composition and it provides quantitative levels corresponding to natural needs of vegetative green plants. Fertilizer is used for foliar feeding of plants during vegetation by spraying on vegetative mass in certain phases of development of the plant organism.
TOPERS working solution is prepared by diluting the basic TOPERS concentrate solution in pure water at a ratio of components of 1: 100. The resulting 1% working solution is used for foliar treatment of the green mass of growing plants in the early stages of development according to the technology of cultivation of a particular crop. The average dose for a single working solution foliar treatment of vegetative field crops is 200-400 liters per hectare. In the processing of plants grown in greenhouse conditions, the dose is adjusted depending on the area which the plant is occupied.
Application technology of TOPERS working solution in the field involves the use of modern models of sprayers for operation with tramline. Technical indicators of modern sprayers allow to process plants at height of 0.5 up to 2.5 meters even in dark time using led light. With working width up to 40 m and more than 12,000 liters solution’s capacity of the tank it makes possible continuous processing of crops on an area of 60 hectares.
Processing of vegetative plants with TOPERS working solution is carried out depending on the specific features of the culture and the passage of the individual phenological phases during the growing season.
It must be remembered that the rate of use of the TOPERS working solution (1%) is 200-400 liters per hectare for each processing of crops.
Adjustment of norm within 200-400 liters depends on the general condition of the plants in crops. Conditions are determined by an expert – the agrochemist through foliar diagnostics of vegetative organs.
Tolerable nutritional status needs 400 liters, good – 300 liters, excellent – 200 liters per hectare.
