Abstract
A combination strip-tiller and applicator is disclosed for conservation farming. The machine is designed to save soil, fertilizer, labor and fuel while producing a higher yield. Unique features of the device include a knife that injects anhydrous ammonia or other chemicals in a broad band under the seedbed. This broad band allows seeds to be planted in the same pass or within a few days without risk of fertilizer burn to the seedlings. The knife also loosens the soil and raises the seedbed. Row cleaners and cultivator gangs can run in the same pass to remove excess crop residual and to further raise the seedbed.
