Abstract

The article presents the results of a production field experiment on ordinary carbonate chernozem for 2022–2023. The influence of liquid mineral fertilizers (LCF 11:37:0 and UAN-32) on the content of available phosphorus in the soil when cultivating chickpeas using No-till technology was studied. It has been established that the application of LCF and UAN increases the content of phosphorus available to plants in the soil during the entire growing season of chickpeas, which confirms the prolonged nature of their action. The effect of liquid mineral fertilizers on the phosphate regime of the soil depends on their type, dose and phase of development of chickpea plants. The greatest changes in the content of available phosphorus in ordinary chernozem were established when using liquid and LCF and LCF with UAN at a dose of 100 l/ha. Keywords: LCF, UAN, CHERNOZEM, MOBILE PHOSPHORUS, CHICKPEAS, NO-TILL TECHNOLOGY
