Biodegradation by Soil Burial Test
A composite sample with the dimensions of 20 9 50 mm
was buried at approximately 10 cm under the soil surface.
The pH and temperature of the soil were maintained at 7
and 32 ± 2 C, respectively. The water content of the soil
was in the range of 30–40% and the weight change was
recorded daily for 22 days. Averaged percentage weight
change was recorded from three independently tested
samples.
