Layered application of mineral fertilizers with the coulter ripper of a combined unit

The applied methods of fertilizing cotton in Uzbekistan have a number significant disadvantages. They do not provide available nutrients to the plant's root system. With distribution fertilizers zone development layers required ratio, coefficient their use and yield increases. (Purpose study) To substantiate design parameters subsoiler's pipeline for three-tier fertilization. (Materials methods) developed distributor three-tiered fertilization is presented. subsoiler equipped with fertilizer pipe, which consists cylindrical inclined funnel-shaped part, high-flow channel lower distributor. In conductive channel, two branch pipes reflective plates are installed, cut moving direct them appropriate soil horizon. (Results discussion) We investigated movement mineral granules along on basis length upper middle tiers was determined.
