Soil Management

To avoid compacting more of the field, the grain cart should run down the same row middles as the combine. An auger extension may be needed on the combine to get the wheel tracks to line up. The wheel spacing on the combine, tractor, and grain cart should be adjusted to all run between the rows.

Finding Win-Wins for Manure: Maximizing Soil Quality Benefits March 6, 2017

Manure offers crop production wins by providing valuable nutrients and helping build soil organic matter and an active soil microbial community. Soils with organic matter levels on the low end of their typical range can benefit the most from manure applications that do not exceed the crop’s nitrogen requirements. Organic matter also improves soil aggregates which in turn helps increase infiltration of precipitation and irrigation water, improves water-holding capacity of the soil, and reduces runoff and erosion. Soils with these characteristics experience greater drought tolerance.
