Abstract

The bioenergetic efficiency of phosphorus-containing fertilizers based on Kyzylkum phosphates under the conditions of pasture and typical gray soils of the Zeravshan Valley has been determined. The highest bioenergy efficiency was found when cultivating cotton on pasture soils is 175 kg/ha of phosphorus (P2O5) against the background of N250K125, when using 120 kg/ha of phosphorus (P2O5) against the background of N240K100 when cultivating corn on eroded soils. On typical gray soils, the use of phosphorus-containing fertilizers in vegetable growing is bioenergetically inefficient.
