Poultry manure improves profits, soil health

A 20-year study by Iowa State University researchers shows fertilizing cropland with poultry manure can benefit soil health and farm profits when compared to a commercial fertilizer. The study looked at long-term impacts of poultry manure on soil quality, crop yield, production costs and water quality in conventional Iowa cropping systems.

Building Soil Organic Matter Takes Time

Our “instant” culture gravitates to testimonials about how to rapidly increase soil organic matter by 1% within 1 to 3 years. Conversations with lenders and landlords regarding rewards on manure applications and multi-species cover crops investments would likely be easier if financial rewards or measured soil physical properties came quickly.

Soil Organic Matter and Its Benefits

Soils of Northern Great Plains are relatively young (11000 to 14000 years old) and have some of the highest organic matter levels (4 to 7%) of all mineral soils in the United States (Overstreet and DeJong-Huges,Read More…
