RU2010144391A - METHOD AND DEVICE OF DIFFERENTIATED PRESEUSED APPLICATION OF BASIC AND START DOSES OF MINERAL FERTILIZERS - Google Patents

Abstract

 1. The method of differentiated sowing application of the main and starting doses of mineral fertilizers, which consists in the fact that both the main and starting doses of fertilizers are applied together with the seeds, characterized in that before sowing they receive and interpret information on the spatial variability of the field fertility parameters in the global coordinate system on based on the responsiveness function of the cultivated crop, taking into account the fertility parameters of each elementary field site and other significant factors, make up the electron a map of the rational need for nutrients of the cultivated crop to obtain optimal productivity, depending on the properties of the used mineral fertilizers, set the required dose for each elementary field, the data from the card is transmitted to a computer / microprocessor that controls the operation of the fertilizer dispenser and the magnetic valves of the distribution head pneumatic distribution system of mineral fertilizers, the sown quantity of fertilizers intended for each the field’s lementary section is divided into two streams - the starting and main doses in the ratio of 1: 5 ÷ 1: 20, the starting dose of fertilizers is sent to the seed sowing system and the mixture is embedded in the soil in the formed furrow at the same depth as the seeds, the main fertilizers are applied locally in the center between rows of seeds and 4-10 cm deeper than seeding, depending on the depth of seeding. ! 2. A device for differentiated sowing application of basic and starting doses of mineral fertilizers, including hoppers for seeds and fertilizers, a dispenser
