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