ENERGY EFFICIENCY OF MINERAL AND ORGANIC FERTILIZERS UNDER CROPS OF SHORT CROP ROTATION IN THE IRRIGATED CONDITIONS OF SOUTHEAST OF KAZAKHSTAN

Abstract

The energy efficiency calculations of application of various of fertilizers for crops (flax, barley, rape, soybean) of short crop rotation are presented in the article. It is shown that the value of the energy coefficient depends both on the types of fertilizers and on the biological characteristics of the studied crops. The use of fertilizers provided an increase in the yield, containing an amount of energy significantly superior to the energy spent on obtaining this increase. The energy coefficient of the studied fertilizers used for spring rape varies from 1,0 to 4,4 units, for oil flax from 2,3 to 8, 8, for spring barley 2,3 -3,8 units and for soybean from 1,63 to 9,8 units. The amount of energy spent on the production and use of fertilizers varies depending on their types and norms and ranges from 2520-18900 MJ/ha. The energy utilization rate of fertilizer, apparently, is positive in all variants of the above units. The least energy-consuming (K -9.8) using mineral fertilizers turned out to be the soybean, which does not require nitrogen fertilizers in comparison with others (flax, barley, rape)
