Garlic on small organic farms is typically either dry mulched (e.g. straw) or grown in bare soil and cultivated for weed control. Farmers would like to see the soil covered to prevent erosion, increase water retention, and improve soil nutrition. However, water retention could increase nematode pressure and green mulches could compete with garlic. Ken set out to see if there was a difference in yield of marketable garlic between cultivation and spring mulches.
