Specific activity of technogenic radionuclides, Bq / kg, ACs / 45 + ASr / 30, rel. units ,, no more 1.0 Effective phosphorus fertilizer for agriculture . In addition to the main biogenic element phosphorus, it contains sulfur and trace elements - magnesium, zinc, manganese, etc., which are also necessary for the normal growth and development of plants. Does not contain ballast substances and harmful impurities (lead, cadmium, arsenic, mercury). Phosphorus and all nutrients of the fertilizer are highly soluble. The mass fraction of assimilable phosphates potentially available to plants is comparable to their content in simple superphosphate. At the same time, phosphate fertilizer is devoid of one of the disadvantages of simple superphosphate - its increased acidity. Fertilizer weakly alkalizes the soil. Fertilizer can be applied in advance, in full dose, without fear of phosphorus loss from leaching. Phosphorus fertilizer is well compatible with other types of fertilizers, it can be used to prepare various brands fertilizer mixtures. With systematic fertilization, soil fertility increases, plants can more easily tolerate adverse weather conditions. Phosphorus fertilizer is used in agriculture for all agricultural, industrial crops and perennial grasses on any soils, mainly for deep processing. It is recommended to use in conjunction with nitrogen-potassium fertilizers. Recommendations for the use of phosphorus fertilizers in agriculture: Terms , the frequency and optimal doses of fertilization should be determined by specialists of the agrochemical service based on the results of soil and plant diagnostics. Approximate doses of fossor fertilization: -for grain e, vegetable and industrial crops - 2-3 c / ha in physical mass; -for perennial grasses (before sowing under a cover crop) -3-4 c / ha in physical mass. The fertilizer has been tested in the Nizhny Novgorod State Agricultural Academy and is recommended for use. Packaging: Phosphate fertilizer is supplied to the consumer packed in polypropylene bags with a polyethylene liner weighing 40 kg The guaranteed shelf life of phosphorus fertilizer is not limited
