Description: The type of soil preparation for planting crops depends mostly upon the crop to be planted, soil type, and expected precipitation. Seed bed preparation facilitates crop growth and penetration of rainfall. In this image, a field of corn stubble is tilled with a disk combined with a following ripper. The disk chops the corn stalks from the previous year's crop and mixes (mulches) the residue with the top 4 or 5 inches of soil. The ripper loosens and aerates soil to depths of up to 18 inches, especially useful for dense (e.g., clay) soils and to treat soil compaction. This combination disk-ripper minimizes the number of equipment passes for seed bed preparation, thereby minimizing planting costs as well as soil compaction caused by the weight of tractors. For most soil types, crops with relatively large seeds such as corn or soybeans may be planted directly after this kind of seed bed preparation. NAL #4845 shows another view of this equipment, while NAL #4846 to #4848 illustrate alternative equipment for similar purposes.
