Cropping tillage implements

Researchers working for the Nebraska Agricultural Experiment Station developed the stubble-mulch or crop residue mulch practice, a highly effective method of soil erosion control (Douley and Russel, 1939). Stubble mulching used subsurface tillage implements that left crop residues on the soil surface and provided some protection against wind and water erosion (Zingg and Whitfield, 1957). 

Triazine herbicides have been important tools in the development and implementation of conservation tillage systems. Postemergence and residual activity, low vapor pressure, weak adsorption to surface crop residue, root uptake, broad weed control spectrum, and crop safety make these herbicides compatible with the high crop residue conditions of conservation tillage. 

Implementation of crop rotation and tillage alone does not prevent the occurrence of pests on the field. If additional mechanical operations are not sufficient, not wanted for economic or environmental reasons or not possible because of... 

Crambe could be cultivated as a cover crop. The decomposition and nutrient release from crop residues of crambe in the implementation of no-tillage system has been reported. Heinz et al. (2011) have reported that the kinetics of residue decomposition in crambe were similar to those of nutrient release with an initial rapid phase followed by a slower one. K, P, and Mg are released more quickly for subsequent crops, while the increased speed of nutrients release occurred around 15 days after the biomass management. Due to a high content of glucosinolates, crambe could also be used as a crop for biofumigation.
