Presentation Abstract
Mustard seed meal (MSM) has been studied as a biofumigant in suppressing the weed growth in an organic way. Previous studies have shown that MSM in soil with a higher sand content was highly effective in suppressing the germination of weeds, and that as clay/silt in sand content increased, MSM effectiveness decreased in suppressing seed germination. Based on these results, it was postulated that clay may have effects on MSM by inhibiting this biofumigant from suppressing the weed growth. Two different types of pure clay--kaolin and montmorillonite--were selected to test at various concentrations. Low concentration of clay in MSM does not seem to have effect on inhibiting the weed suppressive properties of MSM.
