Abstract

In this article, it is based on the fact that in the Republic of Karakalpakstan, when different rates of mineral fertilizers are applied to cotton, which is planted after winter wheat and after repeated sunflower and bean crops, the ammonium form of nitrogen is more than the nitrate form in the 0-30 cm layer of the soil. Also, it is scientifically proven that in the areas where N60P80K60 kg/ha was applied to repeated mosh, the amount of mineral nitrogen was higher than N200P140K100 kg/ha for cotton.
