PRODUCT USES AND DOSAGE:
It can be used as raw material for basal fertilizer,foliage top dressing,seed fertilizer,and production of compound fertilizer,It is widely used in cultivation of rice,wheat,maize,sorghum,cotton,fruits,vegetables etc,It is one of the three major nutrient elements,especially for root crops,such as potatoes,peanuts,garlic,and sweet potatoes.After application,the crop will attain strong roots,shoot out evenly,get plump grains.It can be used in a wide range of soils,and is especially suitable suitable for North,Northeast and Northwest regions in China,where the alkaline soil is phosphorus deficient.The soil will also be significantly improved.According to different types of soil and crop,the dosage is between 225-750 kilograms perhectare.
