METHOD ECOLOGICAL EVALUATION OF TECHNOLOGIES WINTER WHEAT GROWING BY INFLUENCE ON SOIL FERTILITY
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 5
Abstract
The article proposes a method for evaluating the technology according to the intensity of its negative influence on soil fertility indices: strong (deviation from optimum to deterioration is more than 50%), average (deviation from optimum to deterioration more than 25% but not more than 50%), moderate ( the deviation from the optimum in the direction of deterioration more than 10%, but does not exceed 25%), absent (the deviation from the optimum in the direction of deterioration does not exceed 10%). The method can identify the negative effects of technology on the state of the soil and make an informed decision on its improvement or its prohibition in specific soil-climatic conditions. The research was conducted in conditions of field stationary experiments located in the Polissya, Forest-Steppe and Steppe regions of Ukraine. The basic technology of winter wheat cultivation and technology with the application of mineral and organic fertilizers in various combinations, considering the soil-climatic conditions of the location of the experiments. Using the developed method, it was established that in the conditions of Polissya, Forest-steppe and Steppe of Ukraine the technologies of winter wheat cultivation lead to depletion of soils on exchange of potassium forms. In conditions of chernozem ordinary low-humus and chernozem podzolized medium loamy slightly eroded, deterioration of the acid-base conditions of soils was observed. In conditions of the Steppe, along with the potash regime, the technology negatively affected the nitrogen regime of the soil - there was a depletion of stocks of mobile nitrogen compounds. The avoid degradation of soils, the technology of winter wheat cultivation should be improved in the part of the fertilizer system of plants, in accordance with the established negative processes. In the future, the methods of evaluating wheat growing technologies need to be developed based on indicators of the impact on the processes of accumulation and migration of soil chemicals.
