肥として施用するしかないなどの欠点があつた。 Recently, it has been put into practical use as a potassium silicate fertilizer developed by one of the inventors of the present invention. This fertilizer is useful for correcting acidic soil, has slow-release properties, has few concentration disturbances, and has excellent characteristics such as being resistant to leaching.However, on the other hand, the content of fertilizer components is low, making it difficult to use as a raw material for compound fertilizers or chemical fertilizers. There is little flexibility in the mixing ratio of ingredients, and because it is strongly alkaline, ammonia gas is generated when nitrogen fertilizers such as ammonium sulfate, ammonium phosphate, and urea are mixed, making it necessary to apply it as a single fertilizer.

の利点がある。 The novel fertilizer composition of the present invention contains phosphoric acid in addition to potassium and has a higher content of fertilizer components than potassium silicate fertilizer, and can be used not only as a simple fertilizer but also as a raw material for blended or chemical fertilizers. In addition, the fertilizer components of phosphoric acid and potassium are poorly soluble and have very little leaching or runoff, and since they contain only phosphate roots that are absorbed during operation, acidification of the soil is prevented. It has the advantage of being slow-release and has a high utilization rate of both fertilizer components by plants, and the phosphoric acid content is less fixed in the soil, contributing to resource conservation.
以下、実施例にて本発明の新規肥料組成物を説
