How is a chisel made?

The chisel plow is a common tool to get deep tillage with limited soil disruption. The main function of this plow is to loosen and aerate the soils while leaving crop residue at the top of the soil. This plow can be used to reduce the effects of compaction and to help break up plowpan and hardpan. Unlike many other plows the chisel will not invert or turn the soil. This characteristic has made it a useful addition to no-till and limited-tillage farming practices which attempt to maximize the erosion prevention benefits of keeping organic matter and farming residues present on the soil surface through the year. Because of these attributes, the use of a chisel plow is considered by some to be more sustainable than other types of plow, such as the moldboard plow.
