Nitrogen regime of ordinary chernozem under chickpeas when applying liquid mineral fertilizers in the No-Till system properties

The article presents the results of studies on the influence of liquid mineral fertilizers on the content of ammonium and nitrate nitrogen in ordinary chernozem during the cultivation of chickpeas in 2022–2023. To conduct the experiment, LCF 11:37:0 and UAN-32 were used at doses of 50 and 100 l/ha. It was found that the application of mineral fertilizers (LCF, UAN) when growing chickpeas without tillage increased the content of mineral nitrogen in the soil throughout the growing season, and the effect was long-lasting. The results of the study indicate the need to use LCF and UAN to increase soil fertility.
