The content of the category of economic efficiency, methods of its estimation in the methodological plan is determined. The method of determining the economic efficiency of preservation and extended reproduction of soil fertility, which involves two directions of influence of applied soil improvement measures: on the potential and effective fertility of soils, is developed. Approbation of the methodology has been carried out, which showed that in all farms of the planting specialization area all the soil improvement measures under study, at the proper level of their organization, can have a high level of positive influence on the potential and effective fertility of soils. Based on the results of approbation, on the effect on the potential fertility, it has been established that the highest results of the economic evaluation demonstrate the use of by-products, the next position is the combined use of straw and siderates, and the third is the sideration in its pure form. It has been proved that effective fertility, in the context of most calculated parameters, is most affected by the combined use of straw and siderate, then sideration and the third place is the use of straw. In farms with developed livestock production, it is necessary to maintain a balance between the alienation of organic matter from the field and the introduction of manure. Manure application has a positive effect on the preservation and increased reproduction of soil fertility both as a result of the impact on potential fertility and on the impact on effective fertility through increased crop yields. At the same time, the cost of newly formed humus more than three times the cost of manure application. Product Description popup.authors popup.nrat_date 2020-04-02 Close
