Scientists of the Tver State Agricultural Academy (TGSKhA) have developed a selenium-based microfertilizer that allows a quarter to increase the yield of potatoes, reports TASS. The drug is safe for health, said the author of the development Olga Savina.
“A selenium-containing preparation in the form of a fertilizer was developed at the Department of Agrochemistry, Agriculture and Forest Management of the TGSHA. We conducted the first experiments in 2020. Without adding selenium, about 200 centners of potatoes can be harvested from one hectare, and after its application, the yield increases to 250 centners per hectare,” Olga Savina explained.
Thanks to selenium, potatoes become more resistant to stress factors of various nature. The use of the drug will cost farmers about 5 rubles per hectare.
Laboratory studies have shown that microdoses of selenium do not harm living organisms. In addition, its introduction into the soil is safe from an environmental point of view, since selenium is bioutilizable, does not accumulate in the soil and is not washed off into groundwater.
A selenium-containing preparation to increase the yield of potatoes was previously presented at the Inventor and Innovator exhibition in Tver. Now the Tver State Agricultural Academy is preparing an application for patenting a new drug.
