The possibility of producing liquid fertilizers based on nitric acid processing of washed dried concentrate in the presence of monoethanolamine is shown. On the basis of nitric acid extract and monoethanolamine, liquid complex fertilizers with stimulating activity were obtained, composition: P2O5tot. - 10-11%, CaOtot. - 6-7%, Ntot. 12-13% and K2O-5-6%. They contribute to the acceleration of plant growth by 10- 12 days and an increase in yield by an average of 8-10% compared to the control variant. It can be concluded that they can be recommended as liquid complex fertilizers for drip application.
