Soil health and nutrient management: What it can and cannot do

Improved soil health provides several benefits to crops and water quality. However, there are limitations and as a result, some misconceptions exist. This presentation features Chad Penn, Research Soil Scientist at USDA-ARS and Adjunct Professor of Agronomy at Purdue University, who addresses how improved soil health impacts soil fertility and nutrient transport, as well as dispelling common myths.This presentation was originally broadcast on April 17, 2024.

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.

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.

What is the Economic Value of Manure?

Manure has value.  That value may result from improvements in soil quality, increases in yield, and replacement of commercial nutrient required for crop production.   Previous articles on manure’s value have focused on its soil health,  environmentalRead More…
