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.
