Abstract

It was achieved to improve agro physical properties of soil by forming of 22, 41-52,92t/ha green biomass of pea, chick pea, rape and barley when sown asgreen manure as well as tilling it into soil insummer July 10 wheat freed areas, and autumn October 10 cotton freed areas. With a 10-0,25 mm sized of macro aggregates portion was over 2,96-6,9 % in 0,20 cm of soil layer in summer green manure variant and it was over 2,37-6,41 %autumn green manure applied variants comparatively to control without green manure. In 20-40cm of soil layer the portion of macro aggregates differs from the tilling layer, and makes up 69,04 %-68,72%in control variant -without green manure when applied summer and autumn green manure variants, if these indicators are between 71,31-73,53 %; 70,59-73,0 %, it provides soil grainy, serves to increase of the mass of soil and increases soil fertility as well.
