Influence of soil conservation technologies on density and hardness of leached chernozyom

Methods for primary tillage in general did not significantly impact the seal. Options density was described as optimal. The hardness values of the soil were the highest in the embodiment with zero treatment. They significantly exceeded the parameters penetration resistance under moldboard and minimal treatments. The addition of density parameters was described as the best, and under moldboard plowing, in some periods as excessively loose (0,68-0,99 g/cm 3). Against the background of optimal density values for most crops, the highest values were typical of conditions that have emerged in the processing of the type of zero (0,94-1,25 g/cm 3). The hardness values of the soil were highest in the embodiment with zero treatment (22,8 kgf/cm 2). They significantly exceeded the parameters penetration resistance under moldboard and minimal treatments. Moderate and inverse correlation between the density and adding humidity was revealed. The hardness determined by the degree of soil moisture at moderate (r = -0,55) and with a moderate force was related to the density (r = 0,65). However, these relationships were found only for the conditions moldboard plowing. When other of treatment methods were used correlation bond was weak.
