Sampling and degradation of biodegradable plastic and paper mulches in field after tillage incorporation
Plastic biodegradable mulch (plastic BDM) is tilled after use, but there is concern about
incomplete degradation and potential impact on subsequent crops, and we lack a reliable
method to measure mulch degradation post soil-incorporation. We conducted two field
experiments to (i) develop a sampling method to estimate the amount of mulch (fragments
size> 2.36 mm) in the field post soil-incorporation, and (ii) assess the amount of BDM in the
soil after four consecutive years of mulch incorporation. In Expt. 1, we used the quartering …
