SUBSTRATE COMPOSITION CONTAINING BIODEGRADABLE POLY ASPARTIC ACID

摘要

An environmentally friendly bed soil composition containing biodegradable polyaspartic acid having excellent water holding properties and nutrient absorption properties is provided to effectively improve the growth of seedlings when seedlings of horticultural crops and rice were raised. An environmentally friendly bed soil composition contains 10ppm to 10% by weight of biodegradable polyaspartic acid components together with 4 to 5 components selected from Coco Peat, peat moss, vermiculite, perlite, diatomaceous earth, zeolite and loess. The biodegradable polyaspartic acid components are 40% liquid polyaspartic acid. The bed soil is bed soil for horticulture or bed soil for seed bed.
