Description

Mustard seed meal (MSM) has been shown to control weeds and pests in crop fields. Prior work showed that a sandy loam soil was superior to a silt loam in supporting velvetleaf growth suppression by MSM. To explore this difference, myrosinase enzyme activity was measured in both soils. Results showed no significant difference between the soils. Sand content in Michigan silt loam soil was manipulated in order to test the role of sand content on MSM efficacy in suppressing short-term velvetleaf growth. Results showed that sand enhanced the effect of MSM in suppressing seedling growth and germination.
