TOP-DRESSING METHOD FOR FALL WHEAT Russian patent published in 2009 - IPC A01C21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and may be used for the fall wheat crop-producing power increasing. The method includes treatment of vegetative plants with mineral fertiliser solutions consisting of chemical substances with nutrient elements such as boron, iron, potassium, manganese, copper, molybdenum, zinc, nickel, iodine, cobalt, sulfur, aluminium, tin and strontium. The weight of each chemical substance to be used for mineral fertiliser solution preparation is defined to the standard weight of separate mineral fertiliser being in 100 g of the fall wheat and according to the formula: where: m(S) - weight of the chemical substance (S) included into the fertiliser weight and having one nutrient element (E); M_r(S) - relative molecular mass of the chemical substance (S) to be defined to the Mendeleev Table based on the chemical formula of the substance; m'(E) - weight of separate nutrient elements (E) in 100 grams of the grains expressed in grams; A_r(E) - relative atomic weight of the nutrient element (E) included into the chemical substance (S). After that, the mineral fertiliser solution containing all calculated chemical substances is prepared. The mixture of electro activated water - catholyte and tap water at 1:5 ratio with pH=8-9 is used as the solvent of chemical substances. The final solution of mineral fertilisers at 0.0686÷0.1% concentrations is used for the fall wheat crops treatment at the flow rate 100-300 l per 1 hectare of the crops.

EFFECT: increase of fall wheat crop-producing power due to nutrient fertilizer solution optimisation for top dressing.
