The article provides information on the effects of crops on key agrochemical parameters of soil.Before and after
cultivation ofcrops they were studied and compared.The experiments were performed in three steps.The first stage
investigated the effect of pea plants on soil properties by planting them in two terms.The second stage investigates
the role of esparcet, alfalfa, and quince in soil fertility. In the third stage, the effects of variants planted with sudan
grass, alfalfa and sudan grass with alfalfa on the agrochemical properties of the soil were studied. According to the
study, alfalfa was important in increasing the amount of humus in the soil.Compared to the baseline figures, the
amount of humus increased by up to 25 percent during the cultivation.It has been established that vica plants play a
role in making phosphorus in soil more mobile.
