The studing was made during 2000-2007 year in the experiment field in the Maize Research Institute on typical chenozem.
Found that testing means of basic soil tillage don’t influence on soil moisture in the one meter soil layer (0-100 cm).
Density of soil (g/cm3) and total porosity (%) remain in optimal range for this soil type – respectively of 1,19g/cm3 to 1,40g/cm3 and of 45% to 56%.
Soil hardness (kg/cm2) increase compared recorded at the beginning of the study (18.05.2001 year) average for layer 0-40cm with 65,41%; 37,83%; 30,93% and 27,60% for A1, A2, A3 and A4.
Values of the hardness phase (Sp) increased from starting date at the beginning of the study more materially for variant A1 (ploughing at 25-30cm) and A4 (tillage with disc-harrow at 10-12cm). In tillage with flat-cut at 25-30cm (A2), loosening at 25-30cm (A3) and disc-harrow at 10-12cm (A4) percentage of pores occupied water (Lp) increases with 6,31%; 4,31% and 3,65% a pore occupied by air (Gp) increase with 3,90%; 4,17% and 2,04%.
