The received results have shown that the volume weight in a layer of earth of 0-15 cm was the maximum on cabbage culture and has made 0,84 t/m3. On depth in 15-30 cm this indicator increased to 0,93 t/m3 in the field with a clover of the second year of using. Also the tendency of increase of an indicator of volume weight was observed at transition to depth in 15-30 cm on all investigated fields, except a field with culture of cabbage. The lowest value (2,2 t/m3) of specific weight of soil on depth of 0-15 cm is noted in the field with white head cabbage, and maximum high (3,3 t/m3) one characterized a field with cultures of lupine and radish olive. At depth of a layer of earth in 15-30 cm the indicator of specific weight was at level 2,6-2,9 t/m3 for fields with all kinds of cultures. The quantity of water proof units was the lowest and structure! 1,9% at soil research on depth in 15-30 cm in the field with a clover of the second year. The greatest content of water proof units is noted in the field where the cabbage was grown up after green predecessor
