A TPMBS sample with the dimensions of 20 50 mm2
was buried at approximately 10 cm under the soil surface.
The pH and temperature of the soil were maintained at 7
and 32 28C, respectively. The water content of the soil
was in the range of 10–20% and the weight change was
recorded daily for 28 days. Average percentage weight
change was recorded from three independently tested
samples.
