MODERN APPROACHES TO USE OF THE MINERAL FERTILIZERS PRESERVATION SOIL FERTILITY IN THE CONDITIONS OF CLIMATE CHANGE
Abstract
In article it is specified that the first in potentials of fertility soil of Ukraine and first of all chernozems, in recent years owing to a deviation of technologies from it is general the accepted developed zone recommendations and violation of fundamental laws of agriculture, key indicators of fertility significantly lose. Their structure worsens, the maintenance of a humus, organic matter, macro - and minerals decreases. Specified adversely affects productivity of crops that it is especially shown as in a zone of the southern steppe, and in general in Ukraine including due to changes of climatic conditions. Level of productivity of agricultural plants first of all limits security with their moisture which without the optimum content of organic matter by the soil does not keep, is quickly lost on unproductively evaporations, but not on formation of productivity. That most influences growth and development of plants, occupies the second place among factors food. The best conditions of providing plants with nutrients are created on body of a mineral system of fertilizer. It is expedient to bring them compatibly in evidence-based norms. Under such circumstances use of fertilizers most fully remains the existing parameters of fertility of the soil and even improves and especially for proved watch of crops in a crop rotation. At the same time in the last decades volumes of introduction of organic chemistry are significantly reduced that negatively affects a condition of fertility of soils. At the same time there is an urgent need for the most expedient use of mineral fertilizers, selection of their types, forms and ratios for increase in productivity and key indicators of quality of crops. Mineral fertilizers it is necessary to gather additionally taking into account growth of dryness of a zone irrespective of moistening level, they were absorbed by the soil, were evenly distributed in it and were effectively used by plants. At the same time fertilizers are introduced have to affect well key indicators of fertility of soils and to maintain in them positive balance not only basic elements of food, and a humus. In article it is reasonable that liquid mineral fertilizers both simple, and difficult, have certain advantages in efficiency in comparison with types, more widespread in application, firm (loose and granulated) fertilizers.
