The significance of humus content in soils of the
Krasnodar region is decreased. Losses amount is 0,03-
0,05 % every year. The main means of preservation of
soil fertility is the introduction of such organic fertilizers
as manure. The availability of manure’s use has
decreased significantly in connection with the reduction
of livestock in agricultural organizations of the
Krasnodar region. It causes the necessity of searching
of other ways of replenishing of soil fertility. The challenge
is to ensure a positive balance of organic matter
in soil without application of manure. The reproduction
of the soil fertility can be achieved at the expense
of proper selection of agricultural cultivars in the crop
rotation and provision of optimal structure of sown
areas. The modeling of the structure of sown areas
using the developed economic-mathematical model
allows to determine the optimal composition and the
areas of crops for maximum gross or net income with a
positive balance of humus. It is proposed to use the
general indicators of economic evaluation - gross or
net income, increased (decreased) in the value added
of (left) humus to assess the effectiveness of land use.
The calculations were made on the example of the Ltd
Company “Vorontsovskoe” of Dinskoy District, they
may be adopted for any agricultural organization
