BASIC CONSTRUCTIONS OF SECTIONS FOR FERTILIZER APPLICATION IN SECTION OF STRIP-TILL TECHNOLOGY

Abstract

Strip-till technology was formed in the USA on a short corn-soybean crop rotation. Both crops are harvested in September-October and thereby exclude the appearance of post-harvest weeds. In addition, both crops are grown on wide-row crops, and this prompted the emergence of strip cultivation technology. Strip-till technology is an alternative tillage option between traditional plowing and direct seeding. When applying this technology, the soil is deeply loosened only within the row, the rest of the field remains untreated. Structurally, each section for strip soil cultivation consists of such working bodies as a frame, a front slotted disk that cuts the soil surface and plant remains, and also withstands the depth of cultivation. Cutting discs on one rack clear the row of plant remains and lightly mulch the soil surface. The section rack performs tillage to a depth of up to 30 cm, and if additional equipment is available, it can provide fertilizers, including at two different depth values, and the rear roller compacts and grinds the soil surface. The use of this technology makes it possible to reduce the number of operations in one pass of the unit. Also, the above-mentioned tillage technology can solve such problems as high weediness, low fertility of soils with insufficient content of organic substances, the presence of a short growing season, and can also be used in arid regions and soils prone to wind erosion. The disadvantage of this technology is the need to apply a continuous action herbicide. But these economic costs of weed control are not significant in the total cost of tillage. It should be noted that herbicides are also applied according to traditional technology.
