[QUOTE="1wlimo, post: 916567, member: 16646"] Sure what would you like to know? A ideal soil structure starts off with very fine small soil particle's at the surface for good seed to soil contact, yet you require this to be stable ans resist erosion. As we descend down through the soil the particle size needs to increase in a gradual way. Many cultivators can not produce this structure in general, like roto tillers, power harrows, discs, simple field cultivators. While eah have there strengths and uses when used incorrectly especially roto tillers they produce a too deep profile of the fine soil particle's with no graduation. This leaves to soil prone to slum, and erosion, and their action can lead to smearing leading to a pan. The moldboard's lifting and breaking action can rectify many of these problems, High sand soils and high organic soils have very little of any structure due to nature of these materials. [/QUOTE]
