Title: Effect of Potash Application on the Dynamic Change of Potassium Content in Meadow Soil and Crops Yield
Abstract: The method of fixed -site field experiment was adopted in the study. As the potassium content in meadow soil in Hongxinglong Farm is fairly high, the effect of potash application on the increase of crops yield was not very significant. The experimental result indicated that potash application combined with the wheat straw returning to the soil had a positive effect on crops yield and potash utilization efficiency. Potash application and the wheat straw returning to the soil have a significant effect on the decrease of available K and slow-released K content in the soil. It was very important for the balance of potassium content in the soil and the sustainable agriculture.
