Leaves winter food, provides cover, reduces drifting of 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. Saves labor and fuel.
Less machinery is required.
Purchase different machinery. Complete spring plowing by May 1 or earlier. Promotes use of other cover for nesting, whereas late spring plowing destroys many nests and hens. 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.
