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.

Is soil pore structure key to carbon storage?

Dr. Alexandra Kravchenko, Michigan State University professor in the Department of Plant, Soil and Microbial Sciences along with several of her colleagues discovered a new mechanism determining how carbon is stored in soils. A recent article in ScienceDaily drew attention her research findings published in the scientific journal Nature Communications.

Maintaining soil fertility is important for soil health

Maintaining soil fertility is important not only for profitable crop production, but also soil health. In a long-term P and K fertility trial, we can see that there is much greater residue cover in plots that have received adequate potash applications over time compared to where no K was applied. Application of P had minimal to no effect on residue cover.

Manure Impact on Soil Aggregation

If manure increases formation of larger (macro) and more stable soil aggregates, several benefits may result for fields fertilized by manure compared to commercial fertilizer including: Reduced runoff and soil erosion; Increased water infiltration into theRead More…
