METHOD FOR PREPARING WATER-SOLUBLE POWDER FOR NON-PRECIPITATING ONE-PACK TYPE HYDROPONIC FERTILIZER SUBSTITUTABLE FOR COMMERCIAL MULTI-PACK TYPE HYDROPONIC FERTILIZER

摘要

A water-soluble powder, prepared by a method of the present invention, for a non-precipitating one-pack type hydroponic fertilizer can readily prepare a one-pack type hydroponic fertilizer composition, which is a one-pack type and does not need to be respectively dissolved into solution A, solution B and the like. Therefore, a one-pack type hydroponic fertilizer composition prepared therefrom hardly generates precipitates, thereby enabling a clogging phenomenon of a supply pipe to greatly decrease and mineral waste to be reduced, can accurately supply a desired amount of minerals to crops, does not use an expensive and exclusive-use nutrient solution supply device, and can improve absorption ability into crops while lowering concerns for the accumulation of mineral salts in soil or environmental pollution. In addition, the water-soluble powder for a non-precipitating one-pack type hydroponic fertilizer can be applied, as a water-soluble powder itself without preparing a non-precipitating one-pack type hydroponic fertilizer, to crops in order to supply minerals thereto.
