Crop residues left over the winter provide food, cover and reduce drifting snow into shelterbelts and marshes. Soil moisture is increased by increased penetration, reduced evaporation and reduced blowing snow. Erosion from wind and water is reduced. Protective organic mulch remains above ground over water. Costs are similar to fall plowing.
Food is available on the soil surface for pheasants.
Chisel plowing maintains a protective cover on the soil surface and reduces erosion. Chisel plowing is less expensive than moldboard plowing. Plant permanent grass and legume vegetation in sprinkler corners, ditch-banks, roadsides and odd areas. Provides nesting, brood rearing and winter cover. Reduces weed problems and soil erosion.
