Pretillage, postincorporation mulch deterioration measured in broccoli growing experiments
Scientists evaluated three potentially biodegradable plastic mulch products over two growing seasons of broccoli to determine deterioration before and after soil incorporation. Pretillage mulch deterioration was evaluated in both growing seasons by rating the percent visual deterioration. Postincorporation mulch deterioration was measured for 13 months at the end of the first growing season. Results showed that two of the mulches could be suitable alternatives to polyethylene mulch for broccoli production in the Pacific Northwest.
