The changes of soil condition by different technologies of soil tillage to sugar beet

In the years 2005-2008 under field operating conditions on chernozem sons in a sugar beet growing region agronomic trials with sugar beet were carried Out. For this purpose son samples were taken from, topson (0-0-30 m) and subson (0-30-0.60 m) to determine some son properties: humus Content, humus Components, exchange reaction, bulk density and minimum air filled porosity and penetration resistance. In two localities three different son tillage practices for sugar beet were applied: treatment 1 - deep loosening to it depth of 0.35 m, treatment 2 - shallow loosening to a depth of 0.18 m, treatment 3 - ploughing to a depth of 0.25 m. It was found that the difference in results from Studies of basic son properties between treatments evaluated by analysis of variance was insignificant. After four years of studies it call be concluded that the agronomic treatments Under study did not have, my significant effect on Changes in the son environment both in topson and in Subson. Correlation and regression analyses proved significant dependences in topson and Subson.
