Agrophysical conditions and fertility of drained soils

Agrophysical and Biological Properties of Drainage Soils in Land Reclamation

“…They characterize the water-and-air regime parameters and show how many air units match a water volume unit in the soil, etc. these criteria were established to be directly related to the major field crops yield (Mitrofanov, 2012(Mitrofanov, , 2015Moiseev, 2011;Revut, 1968). Minimum, optimum and actual parameters of the above criteria were used in the calculations.…”

“…Further, a consistent decrease in the index parameters was observed with increasing gleying of the drained soil. The yield of cereals and potatoes was in direct connection with complex indices reflecting the physical state of soils (Mitrofanov et al, 2015.…”

“…In this connection, the role of agrophysical and biological factors in the management of soil processes is to a much lesser extent. However, their role in the formation of effective fertility is often leading, especially on waterlogged and insufficiently drained soils (Mitrofanov et al, 2014(Mitrofanov et al, , 2015Moiseev, 2011). The main criteria characterizing the agrophysical factors of soil fertility include the lowest moisture capacity, available moisture reserves, water permeability, density of aggregation, penetration resistance, total porosity, aeration porosity, etc (Kiryushina & Ivanova, 2005;Bondarev, 1994;Kuznetsova, 1990;Maslov, 1979;Mitrofanov, 2012;Revut, 1968;Blokhuis, 2006).…”

“…In growing the spring crops, a special attention is paid to the ridged plowing used in the system of autumn plowing. The soil surface profiling is done to provide a more regular drying of the soil in spring, its earlier high-plastic state and physical maturity, a higher-quality sowing, better water-and-air regime, and finally creating more favorable conditions for the physical, chemical and biological processes occurring in the soil (Mitrofanov et al, 2015.…”
