Abstract
The biodegradable mulching paper could be applied for the environmental friendly agriculture as an alternative to the current vinyl mulching. In order to increase the usability of the mulching paper, the effects of the addition of various inorganic materials on the functionality of the mulching paper were evaluated in terms of practical benefits. The blend of carbonized rice husk powder and perlite resulted in the higher value in the air permeability of the mulching paper, which would be important for the health of plant root. The heat conservative of the mulching paper could be improved by adding the bottom ash or the fly ash because of the pore structure of the ashes. The pH of acidic soil could be neutralized by using the mulching paper containing paper-mill sludge ash or fly ash. The various results showed the addition of the inorganic materials could improve the functional properties of the mulching paper.
