The national tillage machinery laboratory

Abstract

The development of any science is the accumulation and systematic arrangements of facts about a subject. The facts may come from deductive reasoning or experimentation bu in the final analysis the general laws developed must be tested and accepted. At the National Tillage Machinery Laboratory, a research facility of the U. S. Department of Agriculture, the staff is engaged in determining and studying the laws which govern the reaction of soil to forces. The primary aim is to learn about factors which can be applied to the design and use of tillage implements and tractive devices, such as wheel and crawler tracks. Many of the studies are cooperative with industry and state and federal research groups.
