Abstract
The use of mustard seed meal (MSM) as a biofumigant in managing weeds in agricultural settings has been well documented. However it has been suggested that soil types may differ in their ability to foster the deleterious effects of the meal on undesirable plants. Work with MSM in altering velvetleaf seedling soil growth has shown that certain soils were better suited for weed suppression than other soils. The most effective soils had elevated levels of sand in comparison to less effective soils. Furthermore enriching the sand content in soil resulted in reduced seed germination and growth. It is hypothesized that elevated sand content in soil creates air spaces resulting in the effective diffusion of inhibitory volatile MSM compounds throughout the soil and maximizing seed/seedling contact with these compounds. In contrast soil mixtures with elevated silt/clay content should result in less weed inhibition by MSM due to reduced diffusion of volatiles. Experimental results testing this prediction will be discussed.
