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.

Effects of Nitrogen Fertilizer Doses and Application Methods on the Yield of Syr Suluy Rice in the Kyzylorda Region

“…These data are consistent with the work of other authors. The accumulation of dry matter in the aerial parts increases in the process of orgagonesis of plants of various rice varieties and depends on the doses and methods of nitrogen fertilizers [48][49][50]. The authors noted that an increase in the dose of nitrogen fertilizers is associated with the accumulation of dry matter in different varieties of rice.…”

The influence of the stubble biodestroyer and the main tillage method on the nutrient regime of the soil

“…The nutrient regime of the soil is characterized by the content of macro-and microelements in it, it is one of the main factors affecting the yield of agricultural crops. According to V. Gamayunova's research, the higher the content of plant nutrients in the soil, the more fertile it is [1]. Soil fertility is determined by the amount of humus in it.…”

“…Ukraine is one of the richest countries in the world, because it has highly fertile soils, in particular, it owns the largest share of the world fund of chernozems [1]. Soil is the main means of agricultural production, and therefore the success of the agricultural industry depends precisely on soil fertility [1].…”

“…Ukraine is one of the richest countries in the world, because it has highly fertile soils, in particular, it owns the largest share of the world fund of chernozems [1]. Soil is the main means of agricultural production, and therefore the success of the agricultural industry depends precisely on soil fertility [1]. However, in the conditions of modern agricultural production in Ukraine, there is an increase in anthropogenic influence on soils, their biological and humus state is changing.…”

“…Але внаслідок порушення законів землеробства та недотримання зональних рекомендацій щодо вирощування сільськогосподарських культур вони втрачають основні показники родючості, зокрема зменшується вміст в них макро-та мікроелементів, гумусу, а також погіршується їх структура. Наслідком цього процесу є зниження продуктивності сільськогосподарських культур в зоні Південного Степу та в цілому по Україні [1].…”
