biology, agriculture. SUBSTANCE: invention relates to mineral microfertilizers that stimulate process of efflux of photosynthesis products from leaves to economically important plant organs resulting the enhancement of yield of different species of agriculture crops. Agent for the enhancement of agriculture crops comprises ammonium carbonate, copper carbonate ammoniate, zinc carbonate ammoniate and water taken in the following ratio of components as measured for ions, wt.-%: carbonate anions, 50-60; ammonium cations, 38-40; copper cations, 2-6; zinc cations, 2-6; water, the balance. For preparing 1 l of substance near to the maximal concentration it is necessary to take 1 l of 8% ammonium solution, to saturate its with carbon dioxide and to add by 5-25 g of copper carbonate and zinc carbonate. EFFECT: enhanced productivity and quality of agriculture crops, decreased consumption of nitrogen fertilizers in growing, decreased pollution of environment with nitrates. 4 tbl, 3 ex |
