At use of systems of the fertilizers calculated on zero balance of phosphorus and negative potassium, the increase in the maintenance of their mobile forms in an arable layer of earth, insignificant - mobile phosphorus and on 1 class – exchange potassium is observed.

Keywords: soil, fertilizers, mobile phosphorus, exchange potassium, harvest.


Agrochemical state of soil fertility of lands being output from agricultural rotation inOrel region

Article represents the results of agrochemical investigation of fallow lands in the south-east natural economic area of the Orel region. It is stated that at fields output from crop rotation evident fertility deterioration can be detected. This is determined with mineralization slowing down of plant residues, nutrients migration to the deeper soil layers and erosion processes development. The soil degradation degree depends greatly on fallow land age, its fertility factors and erosion manifestation.

Keywords: lands of agricultural designation, soil, fertility, agrochemical parameters.


Agroecological soil assessment in Tuva republic

There was carried out an agroecological soil assessment in the Tuva republic in 1970-2010 years. There were established agrochemical characteristics' and bioproductivity' change trend conditioned by changes of soil formation factors and anthropogenic impact. It is shown that soil degradation is formed through degression, fertilizers dozes reduction and development of wind erosion. There was revealed the role of humus content in soil, holdings bioproductivity and the yield of cultures in soil depository capability to CO2.

Keywords: soil fertility, monitoring, maroon soils, soil depository capability to CO2.
