Studies on Effects of Potash Fertilizer Application

The application effect of potash fertilizer on the rice and wheat and it's influencing to the potash level in the soil were tested.The results showed that the yield of rice and wheat increased by applying potash fertilizer from different sources.The yield of rice increased by the increases of spikes/hm2 and filled grains/spike,the yield of wheat was increased by the increase of spikes/hm2,grains/spike and weight of grain.The content of available K was increased by applying potash fertilizer from different sources,especially by applying chemical potash fertilizer.
