The article of researches is soil, s.g. cultury, mineral fertilizers, pus. Methods of researches: visual, subaccount, chemical, matematyco-statystychney, calculation-comparative. The best terms for a fertility-improving cespititious-carbonate soils were folded at compatible application of organic and mineral fertilizers in moderate norms (240 kg of d.r. on the hectare of area of crop rotation) on a background leave to the rot borne under cultures in two-three fields of crop rotation. Such system of fertilizer provided as compared to control the increase of гумусу from 3,6 to 4,3%, increase of content of nitrogen in a top-soil from 12,1 to 15,1 мг, to phosphorus from 1,8 to 5,0 мг, potassium from 5,2 to 6,4 мг on a 100 gramme of soil. The increase of norm of bringing of pus from 2,2 to 6,6 tons on the hectare of area of crop rotation was instrumental in growth of content of phosphorus and potassium, especially in the pidornomu (20-40 see) layer of soil. The optimum norm of bringing of mineral fertilizers under the long-term herbares of the second year of the use was R60k120, that provided on the average for years researches the harvest of green mass 421-463 ц/hectare and presence of bob in travostoy 49,7-53,9%. On 1 kg of d.r. finished shaving the increase of green mass made 99-109 kilograms. The greatest productivity of winter rye did 30,4-31,9 ц/hectare provide the organo-myneralny systems of fertilizer with the direct bringing under rye of mineral fertilizers in a norm N60Р60К120. The optimum norm of bringing of mineral fertilizers under a barley in 2010 year was application of N30Р60К120 on a background the organic fertilizers of borne under predecessors, that provided a harvest 30,0-32,2 ц/hectare on 1 kg of д.р. finished shaving the increase of grain made 8,0 kg From the separate elements of feed on the increase of the productivity of cultures, upgrading agricultural product, potassium fertilizers had a most influence. Organic fertilizers are borne under the previous cultures of crop rotation in the norm of a 4,5 ton on the hectare of area of crop rotation 83 ц/hectare provided the increase of harvest of long-term herbares of the second year of the use, winter rye 5,6 ц/hectare, to the barley 9,2 ц/hectare. The greatest harvests of wheat 42,9-43,6 ц/hectare is got at bringing of N60Р60К120 on a background 4,5-6,6 tons of pus borne under the cultures of crop rotation, the greatest productivity 589-591 ц/hectare of sugar beets was at top-dressing in the norm of N120Р60К120 + 20 т/hectar leave to the rot. The systems of fertilizer provide the increase of harvest 21-23 metric centners of forage units from the hectare of area of crop rotation at the general productivity of crop rotation 85-100 metric centners of forage units from a hectare. An income makes 1680-1840 Uah/hectare. Product Description popup.authors Іванчук Василь Пилипович Абрамович Степан Якович Процюк Галина Юхимівна popup.nrat_date 2020-04-02 Close
