Phosphatic conditions of sod-podzolic and grey forest soils in Vladimir regoin

The agroecological monitoring statistics that has been collected for many years helped us to reveal the regularity of agricultural and chemical change of soil condition. The generalization of experimental data determined the optimal levels of mobile phosphorus content for sod-podzolic and gray forest soils. We have studied the soil productivity with different fertilizer content and calculated the recoupment of investments by the crop harvests. We also evaluated the condition of soil fertility in the region.

Keywords: soils, available phosphorus, soil fertility, acidity, mineral fertilizers, yield.

Impact of water-soluble organic substance complex-forming ability of organics and crop residues on the multivalent ion mobility

The article shows that soil solutions, water-soluble organic matter of plant residues as well as organics have a complex-forming ability to multivalent cations, significantly increasing their mobility in soil. Application of fertilizers lead to increase of complex-forming ability of soil in relation to the polyvalent metals.

Keywords: soil, fertility, complex-forming ability.

Research of sewage waters application for irrigation in Yemen

Results of researches (2007-2009) of sewage waters from Ibb city (Yemen) influence on red-brown carbonate soil, yield and quality of production. Established that irrigation by sewage waters leads to accumulation of heavy metals in soil and plants, but it concentration lower than permitted limits. Prognosis calculations has showed that copper and cadmium concentration in soil exceeds permitted limits in 10 years, cobalt concentration – 15 years. Recommended cycle application of sewage and ground waters.
