Abstract
The article presents the results of short-term field experience for 2021-2023. Experience is laid down in the hospital of agricultural chemistry and plant protection FSBSI “FRARC”. The effect of the use of potassium humate and the humic preparation “Bio-Don” on the content of mobile nitrogen forms in the Calcic Chernozem in the cultivation of the pea Alliance (Pisum sativum L.) was studied. The experience scheme included options using mineral fertilizer (Azofoska 40:40:40) and without its use. Humic preparations were used in the phase of forming beans foliric, both together with insecticide and without it. It was established that the use of potassium humate shows a positive tendency to accumulate nitrate nitrogen in the Calcic Chernozem. The use of the “BIO-Don” humic preparation per year with an increased amount of precipitation has led to a decrease in the N-NO3 content, which may be associated with the migration of this form of nitrogen down into the subsoil horizon. The use of humic stimulants affected by the forms of ammonium nitrogen, which is available to plants, practically did not affect.
