Application in Agriculture
Suitable for various crops, can be used as basal fertilizer,topdressing,types of fertilizer and foliar application. Basal amount of general acreage 10-12.5kg,types of fertilizer consumption acreage 1.5-2.5kg,spray application 0.5%-2% is appropriate. Potassium in soil have been generally, does not leak, but the difference in fertilizer retaining capacity of sand on the need to ''Eat smaller meals" measures,usually potatoes,melons and other crops on the application of potassium is best, using a wide range of large amount.
