Experimental studies of combined coulter

Currently, the issue of using combined machines with subsurface fertilization is relevant. An important condition for sowing is the uniform distribution of seeds and their embedding in the grooves along the depth. Since in the future it will affect the quality of germination of grain seeds, and also affects the intake of nutrients from the soil. When the seed drill moves along the field, oscillations of the coulter occur and accordingly it deviates from the set parameters that affect the uniformity of the seeding. Different suspension types are used to reduce seeding fluctuations. The article considers the method of experimental study of the coulter and comparative analysis with a serial coulter on the uniformity of distribution of seeds by sowing depth.
