Weed management is a primary challenge for organic grain growers, especially in dryland regions where minimal tillage practices are necessary to reduce soil erosion. Growers depend on integrated approaches to control weeds and often use multiple methods. Consistent management is necessary to control weed biomass and seeds, both in-season and for the duration of organic production. Because organic grain systems attempt to mimic natural ecological systems, weed management is rarely independent from soil-building and crop production methods.
