Effect of Different Land Tillage on Agrophysical Properties of Soil

Abstract

When plowing is carried out in different periods and methods after the harvest of winter wheat, by the end of the actual growth period of cotton, when the agrophysical parameters of the soil are analyzed, in the 1st and 2nd options, when plowing is carried out at a depth of 28-30 cm after winter wheat without irrigation and with irrigation in the summer, the increase in volume and mass of the soil observed. That is, option 3, after winter wheat, plowing at a depth of 28-30 cm in the summer and planting a repeat crop, and then plowing at a depth of 28-30 cm in the autumn, compared to the option of plowing the soil (0-30 cm) in the layer of 0.03 and 0.05 g/cm3 and and it was found that it decreased by 0.04 and 0.03 g/cm3 in the sub-driving (30-50 cm) layer. It was found that the porosity was proportionally higher in the driving layer (0-30 cm) by 1.1 and 1.8% and in the sub-driving layer (30-50 cm) by 0.8-0.8%.
