Abrasive grit, applied at high pressure and directed at plant base, can control weeds and increase yield. We evaluated fertilizer [pelletized turkey (Meleagris gallopavo) litter] and non-fertilizer [walnut (Juglans regia) shell] grits for maize and soybean in-row (IR) weed management. Grits were applied at V1 and V5 of maize, and V1 and V3 of soybean. Between-row weed cultivation was done alone (BR), or in combination with grit (I/B), after grit application. Small weeds (<4 >cm) were controlled after grit treatment, but, larger broadleaf weeds, grass weeds (treated when growing points were below ground), and later emerging …

Weed management is the main yield-limiting factor in production of organic crops. Currently, organic producers have limited resources available for in-row weed management. Flame weeding has been recognized for its potential as one part of an integrated approach at weed management in organic systems. Flame weeding uses propane fueled torches to heat plant tissue and denature proteins, thus injuring or destroying the affected tissue. When properly timed, flame weeding can effectively be used for weed control in corn and soybean fields. Corn and soybean have both shown tolerances to flame weeding and minimal yield loss with well-managed and timed flame …
