Tillage systems for crop production have been studied for many years in various parts of the world. The traditional and probably the most used tillage and rather thorough seedbed preparation is practiced prior to planting. However, the concept of tillage requirements has been changing rapidly. Researchers have developed new tillage methods that differ significantly from the more conventional systems. This research was conducted to see how two of these new tillage methods could affect some of the soil physical parameters when compared with the conventional system. Core sample from a long term tillage corn-planting project located at Pinney Purdue Agricultural Center in northern Indiana were used to measure the effect of conventional spring plowed, chisel plowed, and coulter plant on physical properties of Runnymede loam (typic Argiaquoll) and Tracy sandy loam (typic hapludaflt) soils, at three depths (0-10 cm, 10-20 cm, 20-30 cm). At the first two depths, the chisel system usually had the lowest values for bulk density and highest values for total porosity, on both soils. The inverse situation was represented by the conventional system. The coulder system usually occupied an intermediate position. The tillage systems differed little in water content by volume, at each depth and at each tension ranging from 20 to 100 cm water. Tillage systems affected pore size distribution differentially. The effect depended upon the soil type and soil depth. It appeared to be greater on Tracy sandy loam than on ....................
