Leaching amount of nitrogen in the ball fertilizer less leached out than that in the granular chemical one. However, more nitrate nitrogen in the ball fertilizer leached out as compared to the granular chemical one at the early stage. Coating of clayey' soil on the ball fertilizer decreased the leaching of nitrate nitrogen. The ball fertilizer which contained Azolla and granular chemical fertilizer with applied together with Azolla also indicated similar effects. Corn grain yeilds in these plots were in the order, granular chemical fertilizer which applied together with Azolla>ball fertilizer which contained Azolla>ball fertilizer>granular chemical fertilizer. Grain yield of peanut increased with increment of applied amount of micronutrient fertilizer FTE and rate of perfect grain was also improved.
