Scientists at Kazan State Agrarian University have patented a new planting apparatus for potato planters that simultaneously tackles two critical challenges: automatic sorting of seed material and protection of tubers from mechanical damage during planting. The innovative design features a drum with cylindrical cells, the inner surfaces of which are coated with an elastic material. This soft coating cushions the impact when tubers are picked up from the hopper and completely eliminates rigid contact with metal, preventing cuts, bruises, and cracks. Additionally, an elastic mesh installed at the bottom of the drum allows stones and soil clods to fall out by gravity, acting as a built-in sorter that removes abrasive debris without the need for costly manual sorting of seed potatoes.
This development holds immense practical value for agriculture, as Russia ranks among the world’s top five potato producers, and a significant portion of crop losses occurs precisely at the planting stage. Damaged tubers become vulnerable to pathogens, rot in the soil, produce uneven shoots, and reduce marketable yield per hectare. The new apparatus offers a comprehensive solution: it ensures uniform planting spacing—which directly affects each plant’s nutritional area and the commercial quality of the harvest—while keeping every tuber intact. When each cell reaches the discharge opening, the tuber gently drops into the furrow without jolts or impacts against hard surfaces. Whole tubers are less susceptible to disease and produce more vigorous, even seedlings. The machine was developed by a multidisciplinary team of engineers and agronomists, ensuring that it meets the real-world needs of modern agricultural practices and offers a ready-to-use solution for improving the profitability of potato farming.
