At the present time the agricultural sector has become flexible and changeable in order to supply sufficient food for the world’s population. In this challenge, farmers in a number of developing countries are looking for a new technology to increase crop yields and incomes, reduce the amount of fertilizer used and decrease environmental damage to the atmosphere and water. These issues play a key role in the sustainable development of agriculture. This paper presents the results of a research based on modernization of the seeder SZ - 3, 6 made by a Russian manufacturer and equipped with deep placement fertilizer technology. The seeder SZ - 3, 6 is designed by a Russian manufacturer to drill seeding of cereals (wheat, rye, barley, oats), legumes (peas, beans, soybeans, lentils, chickpea, lupine) with simultaneous application of fertilizers. The basic version of the seeder applies fertilizers not deep in the soil, 5 - 10 cm, but after modernization, by installation of additional equipment of deep placement fertilizer technology on the seeder, the depth of fertilizers will be achieved up to 10 - 25 cm. The depth of fertilizers more than 10 cm allows plants to grow throughout the all-growing season. Deep placement fertilizer technology is an innovative and a profitable practice, which serves not only reduction of wastage and excessive use of fertilizer but also mitigate negative impacts induced by fertilizer application on the environment. This, proven by experts, fertilizer application technology achieves average yield increase. The purpose of modernization of seeder SZ - 3, 6 is to achieve a cost-effective model, which could be equivalent with more expensive original one. The construction and using of deep placement fertilizer technology in modern agriculture are described. The results indicated a theoretical scheme for the seeder equipped with deep placement fertilizer technology as well as describing the working principle of the seeder during the application of the deep placement fertilizer technology. By using the modified seeder, we are able to increase of average crop yield with better quality and minimization of usage of fertilizers.
