The agrochemical and economic characteristics of the application of a magnesium-containing phosphoric fertilizer enriched with a biological product based on Juniperus plant extract, potassium borate in the amount of 1.5 and 2.5 wt. % and organomineral fertilizer based on magnesium-containing phosphoric fertilizer and a biological product containing a plant extract of the Juniperus family, potassium borate, obtained at a mass ratio of 1:1. The study of agrochemical efficiency was carried out in vegetation and field conditions. From the data obtained, it follows that the magnesium-containing phosphoric ferti-lizer and organomineral fertilizer enriched with the biopreparation favorably differ from the micro-fertilizer of the MERS brand B. They have a positive effect on the growth and development of plants and provide an increase in the yield of raw cotton 0.6-2.4 C/ha, allow you to get income from the additional crop 9000 - 37 500 tenge / ha, saving due to the price difference of 7500 - 11 625 tenge/ha, contribute to the accumulation of addi-tional nutrient N, P2O5, K2O elements in the soil after harvesting for 5.5-20.8 mg/kg of soil and humus 0.05-0.1% (2.0-4.0 t / ha).
