Reducing the environmental risks of using mobile energy-saturated units during seed potatoes growing taking into account the patterns of heat and moisture transfer within the root spreading zone in the soil

Because potato is a crop, demanding moisture supply conditions its yield depends on the ability to use accumulated during calendar year by root system growing season. However, intensification of technological methods production using powerful energy-saturated mobile agricultural units leads significant deterioration soil condition due over compaction arable and subsoil horizons which hinders normal mode movement intrasoil development plants. Reducing number passes across field possible when combined that perform several processes in one pass. For this purpose, multifunctional potato-planting unit has been developed at St. Petersburg State Agrarian University combines preplant tillage, planting seeds, agrochemicals, pesticides water-retaining agents, as well deep loosening interrow spacing formation full-volume ridges. The conducted studies have shown effectiveness such providing favorable for growth
