ABSTRACT:
A method and implement for facilitating and fostering the germination and sprouting of seeds of row crops, particularly under encrusted soil conditions, and eliminating the need for using herbicide for most common weeds in growing row crops by covering the rows of seeds with a layer of loose soil after the seeds have been sown in cultivated soil and prior to sprouting and emergence of the crop through the soil. Preferably each layer of loose soil has a generally convex cross-section with a slight depression directly over the row of seeds. The implement for forming the convex layer of loose soil has a pair of laterally spaced apart discs which break up into fine particles at least a portion of the soil on each side of the row of sown seeds and propel a portion thereof onto a deflector shield received between the discs and overlying the row of sown seeds which directs such particles into a layer of loose soil overlying the row of sown seeds.
