Changes of agrochemical properties of standard black soil in different systems of main soil tillage and fertilizing in the central forest-steppe Ukraine

Abstract

The influnce of the four systems of main soil tillage and fertilizing
on the changes of agrochemical properties of standard black soil
and efficiency of cultivated crop rotation has been shown. The
statistically reliable increasing of humus content in the plow layer
of soil in two crop rotation for a long shallow cultivation and
applying into each hectare of arable land 12 tons of manure +
N87P114K114 has been established. In the field five-course rotation of
the central forest-steppes Ukraine deep (28–30 cm) crop plowing in
one field (under a second maize where manure is applyed) is recommended. Shallow crop plowing (10–12 cm) is recommended in the rest of the field.
