Sustainable management of soil resources for adaptation to climate change

Abstract

The questions of sustainable management of soil resources are shown. It is directed to the neutral level of soil degradation and agro-climatic adaptation of agriculture to climate change, promote rational use of resources, conservation and restoration of biodiversity. It is necessary to regulate the load on soils and take into account their ability to self-healing. Unbalanced use leads to a deterioration of the soil quality, water sources, loss of biodiversity, reduced environmental sustainability and ecosystem services which they provide. This question is especially actual with climate changes. Adoption of the three conventions of the United Nations is showing it. Degradation is one of the most important problems in the world. Its causes and unresolved problems of the soil resources management in Ukraine are indicated. In global climate change, the role of adaptive farming systems increases. It contributes to an increase in land productivity and sustainable use. Reducing the soil moisture content reduces mobility and availability of nutrients for plants. It requires the optimization of plant root nutrition through the mineral fertilizers. Measures for adaptation of agriculture should be integrated and cover all possible agricultural practices which can improve the plant growth. It is proposed to grow crops hybrids which resistant to temperature changes and water deficiency, to optimize the fertilizer system (by nitrogen, phosphorus, potash fertilizers, microfertilizers), moisture-saving soil cultivation systems. The use of irrigation and the expansion of irrigated land are essential for maintaining the “climate optimized” agriculture. Key words: adaptation, soil resources, degradation, fertilizers, irrigation, climate.
