内容記述(抄録等)It is thought that using slow-release fertilizer is one way of reducing groundwater pollution from intensive fertilizer application. We confirmed the effective use of coating fertilizer, which is one of the slow-release fertilizers, in two experiments. The first experiment was eluviation under controlled conditions, and the second was a pot experiment using cucumbers with coating fertilizer marked with heavy nitrogen. The results are summarized as follows. 1. Experimental eluviation 1) Eluviation quantity from readily available fertilizer is greater than from coating fertilizer. 2) Nitrogen quantity in soil of coating fertilizer is greater than of readily available fertilizer. 2. Pot experiment using cucumbers 1) Eluviation quantity from readily available fertilizer is greater than from coating fertilizer. This result is the same as the experimental eluviation. 2) Nitrogen recovery rate to plants for each period is higher in coating fertilizer than readily available fertilizer. 3) In upper soil, the residual quantity of applied nitrogen-fertilizer decreased quickly over time with readily available fertilizer, but it remained at high levels with coating fertilizer.
