INFILTRATION

Most producers and researchers have found more advantages and fewer management problems as the number of years in no-till increases.

The problem of water saturated surface soil at seeding time is often cited as a primary problem of zero tillage. This occurs only until soil conditions improve to allow excess water to move deeper into the soil.

Since root systems are not disturbed by tillage, root channels allow greater movement of water deeper into the soil. Earthworm populations increase significantly under no-till conditions. The positive effects of earthworms may be an important factor in successful no-till programs.

Along with the value of earthworm channels in increasing water infiltration, the importance of earthworm activity in incorporating residue and improving soil aeration should not be underestimated.

Anchoring the stubble in the soil with a fall tillage operation may help reduce wind erosion, but it won't catch and hold snow for much needed spring moisture. Stubble-trapped snow is a kind of "insurance policy"" for your no-till farming operation. Most of the snow in the lower picture ended up in the bush at the edge of the field.
