Cover crops may be rolled and crimped using an apparatus which may be rolled across a field at a relatively high speed without excessive vibration. The apparatus includes a substantially cylindrical drum which has a plurality of rows of outwardly extending blades projecting therefrom. The blades may be wave-shaped, curved, substantially straight and discontinuous, blades paired with a plurality of spaced apart outwardly extending rings, or combinations thereof. In use as the apparatus is rolled across a field having a crop thereon, the blades contact and crimp the stalks of the crop, effectively killing the plant.

A method of cultivating crops and cover-crops, interactively and sustainably, using a novel hot water apparatus. The apparatus enables the farmer to prepare a soil bed for planting with a no-till method that: controls nematodes and soil pathogens, promotes nutrient cycling of cover crops and organic materials, kills weeds and weed seeds, and cultivates healthy soil micro flora. A low-pressure (5-60 psi) hot water (120-209 F) delivery system, characterized by a flexible mat which evenly distributes water to the underside of the mat where an attached layer of material with a high water holding capacity saturates and conducts scalding water onto the weeds. A hot water recirculation and heat exchange system reduces water demands while maintaining a high thermo charge in the mat. After soil cools, plants or seeds are planted directly through the mulch of dead weeds or cover crop. Inoculation of soil of microbes promote soil health and crop production.

A tilling cultivator and associated method is disclosed for strip tilling cover crop in preparation for primary crop planting. The tiller includes a pressing drum having a band coulter for cutting surface and subsurface cover crop residue roots and compressing the cover crop into the soil.

The present invention provides transgenic cover crop plants which after harvest degrade the hemicellulose and cellulose therein to fermentable sugars which can further be fermented to ethanol or other products. In particular, the transgenic plants comprise cellulase, hemicellulase and optionally ligninase genes from microbes operably linked to a DNA encoding a signal peptide which targets the fusion polypeptide produced therefrom to an organelle of the plant, in particular, the chloroplasts. When the transgenic plants are harvested, the plants are ground to release the hemicellulase and cellulase which then degrade the hemicellulose and cellulose of the transgenic plants to produce the fermentable sugars.

Each of the plurality of roller-crimping devices having an exterior surface configured to at least partially crush stems of residual plant matter, and being individually movably mounted to the frame such that each of the plurality of roller-crimping devices will move at least vertically with respect to the frame when subjected to a temporary increase in resistance caused by an encounter with a non-uniform region in the field.

Active coulters are integrated into a planter for a walk-behind tractor. The coulters are “active” (rather than passive) because the coulters are powered (i.e. actively rotated) directly by the walk-behind tractor, rather than passively rolling as the tractor is propelled across a field. The active coulters cut cover crop residue on the surface of the field so that the planter seed drill can plant seeds into the soil beneath the (preferably) flattened cover crop residue on the surface of the field.
