Order on the State Accounting
of Fertility Indicators of Agricultural Lands
Accounting of fertility indicators of agricultural lands includes
collection and generalization of results of soil, agrochemical,
phytosanitary, ecological and toxicological surveys of agricultural
lands.
The accounting of indicators is carried out for the purpose of
providing stakeholders with information on the condition of fertility
of the specified lands.
Purposes:
a) formation of complete and reliable information on the state and
dynamics of agricultural land fertility;
b) identification of negative results of economic activity on
agricultural lands;
C) identification of reserves to ensure the sustainability of agricultural
production;
d) formation of the state informational resource on the state of
agricultural lands in terms of fertility indicators
3. Background
