Fk. Khaziev et al., THE EFFECT OF AGRICULTURAL PRACTICE ON SOME FEATURES OF TYPICAL CALCAREOUS CHERNOZEM, Eurasian soil science, 31(3), 1998, pp. 299-304
The application of organic and mineral fertilizers (60 t/ha manure and
25 t/ha green manure against the background N90P60K30) in crop rotati
on contributed to the stabilization and improvement of agrophysical pr
operties and humus state of the soil and increased the productivity of
crops. The average gain in yield for five years varied from 0.45 to 1
.19 t/ha (fodder units). The highest yield (3.57-3.61 t/ha) was achiev
ed under the application of manure (90 t/ha) and manure (60 t/ha) and
green manure in combination with N90P60K30.
