GROWTH PROMOTER FOR AGRICULTURAL CROP

摘要

PROBLEM TO BE SOLVED: To obtain a growth promoter capable of culturing and producing agricultural crops with good seedling and high growth rate by reviving ruined or fertility-lost agricultural soil or regenerating soil fertility. SOLUTION: The growth promoter has a prescribed-shaped porous foamed structure formed by foaming a siloxane and silanol salt polymer solution at 100-300°C in an expansion of 15-50 times to form an air permeable water holding base material. The air permeable water holding base material is mixed with decomposed organic materials fermented and decomposed by soil microorganisms are mixed in a proper ratio by volume.
