Summary. The work presents the analysis of results of fifty-year summer monitoring of fertility conditions of soils of the south-east and southern administrative districts of Voronezh region, as well as agroecological condition of arable land at 01/01/2015. The results of the I-VIII cycles of the inspection showed that for this period the essential changes on the humus content and pHKCI did not occur. The average weighted humus content of the zone is 5.2%; soils are characterized as low-humic. The general part of soil has neutral reaction. The weighted average content of mobile phosphorus in arable lands increased by 31.3% and reached 88 mg/kg (the average provision). The weighted average content of mobile potassium grew by 11.4% and reached 127 mg/kg (the high provision with mobile potassium). The soils of the examined area are low provided with such biogenic elements as zinc, copper, cobalt, manganese, which limits the growth of productivity of crops. There is an expediency of use of microfertilizers. According to the gross content of salts of such heavy metals as zinc, lead, mercury and cadmium, the arable soils of the surveyed areas related to the first group, according to the content of arsenic–to the III group.
Keywords: fertility, soil, dynamics, humus, phosphorus, potassium, acidity.
