N. Sokolovski" popup.description2 Subject - the regularities and the standardized indices of the systematic fertilizers application effect on yield, production quality and soil fertility. Object - to create the information database on experimental data of the stationary field experiments with fertilizers and on the basis of it to work out the standards and mathematical models for optimization and prognosis of the agriculture crops yields, production quality and soil fertility restoration. Methods - the systematic analysis of experiments data and the statistical information processing and modeling methods. Theoretical and practical results - standards are worked out for the grain crops yields due to the natural soil fertility and the standards of yield gains due to the optimal mineral fertilizers rates for the individual agriproductional groups of the Ukrainian soil. The information data base is created on the basis of actual information of the stationary field experiments with fertilizers for the individual soil-climatic zones of Ukraine. The mathematical models are worked out for the calculation of yield, production quality and soil fertility changes for the different fertilizing systems. The prospective assortment is worked out for the complex mineral fertilizers and up-to-date agritechnology of its use. Novelty - the new regularities and standards are obtained on the effect of the different fertilizing systems on the yield, production quality and soil fertility. Effectivity - the working out provides the automatizing of calculations in the computerized technologies creating, which will rise the paying out of the mineral fertilizers 1,5-2 times and the saving of those to 25-20 %. Field of use - computerized technologies in agriculture. Product Description popup.authors popup.nrat_date 2020-04-02 Close
