MANUFACTURING METHOD OF EFFERVESCENT PELLET TYPE SILICIC ACID FERTILIZER FOR FRESHWATER CROP CULTIVATION

摘要

The present invention relates to a method for preparing a foamable pellet type siliceous fertilizer for cultivating fresh-water crops and, more specifically, to a foam-expandable pellet type fertilizer composition for cultivating rice, which contains a silicate in a mixture of a carbonate and an organic acid, and enables mechanical spraying, such as power spraying or unmanned helicopter spraying. In addition, the pellet type fertilizer is prepared by mixing 10-50 parts by weight of a silicate, 20-80 parts by weight of a carbonate, 20-80 parts by weight of an organic acid, and 5-30 parts by weight of a vehicle, putting the mixture in a pellet making machine, and combining the mixture through the treatment at a temperature of 68-83C. By preparing the pellet type fertilizer for cultivating fresh-water crops, spraying can be carried out using a machine, such as a fertilizer power sprayer or an unmanned helicopter, which is effective in the treatment of a large area with siliceous fertilizer. In addition, when the soil is top-dressed with a fertilizer, which is prepared in a pellet type of small dosage form rather than a tablet type, the siliceous fertilizer is uniformly scattered without a silicate component being one-sided.
