Abstracts

A two-year field experiment evaluated the effects of different weed control measures (organic and synthetic mulches, herbicides, and controls) on soil pH in angelica (Angelica archangelica L.) cultivation. Most treatments did not significantly affect soil pH at the 0 - 30 cm depth. However, sawdust mulch consistently caused the greatest reduction in soil pH in both experimental seasons, indicating a pronounced acidifying effect. In addition, silver-brown polyethylene mulch foil resulted in a statistically significant pH decrease, likely due to enhanced organic matter decomposition and accumulation of organic acids. These findings highlight the importance of mulch selection, as certain materials can alter soil chemical properties and should be considered in sustainable angelica production systems.
