Improving meliorative condition of salted lands on the basis of using local mineral agro ores

Field experiment was carried out in order to improve salty lands of the Republic of Karakalpakstan. The aims of the experiment are improving meliorative condition of soil, increasing its productivity, defining influence of organic fertilizers and local agro ores. As a result of investigations it was obvious that when mineral fertilizers were fully used, the amount of chlorine and other salts increased, soil productivity decreased at the end of vegetation. When the amount of mineral fertilizers was shortened to 25% and additionally 10, 20 t/ha organic fertilizers and 1,5-2,0 t/ha celadon green from local agro ores were used, increasing the amount of chlorine and other salts slows down, the amount of nutritious elements in the structure of soil also balances. It was defined that for improving salty lands it is effective using N180P130K90 kg/ha mineral fertilizers, 20 t/ha organic fertilizer, 1,5-2,0 t/ha celadon green in improving soil and increasing cotton productivity.
