Title: Study on the Dynamic of Soil Potassium and Potassium Absorption by Crops in the Wheat-maize Rotation Period
Abstract: This article researches the relationship between the crop absorption and the available potassium dynamic under different potash application by long term location experiment using system method.The result indicates that the potassium absorption by crops increases with the increment of potassium fertilizer application.The available potassium presents an M-shape dynamic in the wheat-maize rotation life-cycle.The above potassium dynamics are attributed to the collaboration of many factors such as crop absorption,fertilizer,climate and so on.Potassium fertilizer application increases the potassium supplying power and decreases the potassium consumption of soil.
