Mechanical Properties and Degradability of Bio-degradable Agricultural Transplanting Pot Containing Rice By-product

The bio-degradable transplanting pot containing rice by-product (rice-hull and rice-bran) were developed,and tested their ability for agronomic use. Rice by-products were crosslinked with biodegradable aliphatically aromatic copolyesters or urea resin for making transplanting pot. Mechanical properties and degradability of these pots were measured and compared to those of the Jiffy pot (commercially used bio-degradable pot). Mechanical strength was higher than that of Jippy pot, and bio-degradability was excellent under the actual field condition. In addition, the pot could be degraded within 3 months under the ground. Our result indicated bio-degradable pot containing rice by-products has a great potential for such agronomic use.
