Fertility indicators of soils in the Siyazan-Sumgayit massive

Recently, the reforms in the direction of increasing manufacture of the agricultural products, ensuring food safety have given their positive results. There are some opportunities to produce material goods, to ensure economical development, to raise people’s standard of living in the country. As it is known, Azerbaijan possesses natural underground and surface resources. But the soil and water supplies are quite limited. Lately, some difficulties have been created in provision of agricultural plants with irrigated water.It should be noted that, one of the factors negatively affecting the agriculture is soil salinization and solonetzification. The soil salinization led not only to decrease of the productivity and qualitative indicators but also to disturbance of the ecological balance, to long-term loss of fertility and other insufficiencies. Today elimination of the same difficulties is considered one of the most important problems.From this point of view, the researchers conducted in the deluvial salinized soils are important and definition of the fertility indicators in the same soils is considered one of the most important issues.
