Conducted analytical studies, resulted in the construction of a new mathematical model of plane-parallel motion combined simultaneous sowing unit and bandpass mineral fertilizers. If you use the original equation in the form of Lagrange II-the kind, the system was composed of six differential equations of motion, that describes the behavior of the combined unit with its plane-parallel motion. Defined analytical expressions for the forces, that act on the machine unit, can be solved on the PC.

In this work have considered the problems of soil compaction and the main nutrition of plant in the system of precision farming in the conditions of the main grain-sowing regions of Northern Kazakhstan. The specific examples show the condition of the soil, the level of their supply with nitrogen and phosphorus. Technological and technical solutions are proposed for the differentiated use of basic doses of mineral fertilizers and soil decompression

The working members of the batch-combined machine for minimum tillage and crop tending are combined into two separate batches. By means of the first batch, there are performed simultaneously tilling and sowing operations, but the second is intended for surface tillage and crop tending. During just one field day, the machine is capable of performing 8…10 agricultural operations, and its working members can work in three modes: 1. Soil loosening without furrow slice overturning, when the main tillage unit (wedge) is in its working condition together with lateral knives (for the eroded soils); 2. Clod furrow slice pulverization and mixing, when the main tillage unit (wedge), lateral knives and rotary tiller are in their working conditions (for the non-eroded soils); 3.Cultivation of humid soils with a partial overturning of furrow slice, when the main tillage unit (wedge), lateral knives and rotary plough (instead of tiller) are in their working conditions. The cost of oil and lubricants and operating time are reduced by 2…2,5 times, and besides, the agrotechnical terms reduce considerably. The design formula for tillage output envisages both broken and unbroken soil strips. This formula can be also used for calculation of the machine output during cultivation, sowing, cutting the irrigation channels and so on. The proposed batch-combined machine can be also considered as energy-saving, resource-saving, environmental and advanced technology.

The paper researches the influence of two tillage systems – conventional tillage and strip tillage on soil nutrients content, soil acidity and microbiological activity over a reseаrch period of four year – from 2014 to 2017 included. The test are carried out on the same fields in Northeastern Bulgaria. Soil nutrient testing can help determine the necessary amount of fertilizers to be used on a specific field.
