Managing Nitrogen to Reduce Losses as Nitrous Oxide September 18, 2017

Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, benefit both farmers and the environment.

Value of manure

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.
