Two soil aggregates: manure (left) versus a heavy soil aggregate

Soil Organic Matter and Its Benefits August 7, 2017

Soil organic matter is critical to maximizing soil biological activity. Rotating crops, applying manure, reducing tillage, and increasing biomass production are among recommended practices to increase soil organic matter.

Ephermeral gully in a corn field.
Field 1. Research indicates that when used in combination with other measures, manure can play a valuable role in increasing soil aggregate size and reducing soil erosion such as from the ephermeral gully in this corn field.

Using Manure as an Aid in Reducing Erosion and Runoff August 3, 2017

By improving soil properties manure applications can help increase water infiltration and reduce soil erosion when used in combination with other soil conservation practices. Care needs to be taken, however, in how often and how much manure is applied to avoid P loss in runoff and erosion.

How Manure Impacts Soil Aggregation July 6, 2017

Researchers compare differences between soils fertilized with three types of manure versus commercial products and note four benefits, including an increase in water-stable large macro-aggregates that hold P differently.

Applying Manure Before Seeding Alfalfa April 7, 2017

If you're looking for a place to spread manure, a heavy dose before planting alfalfa can pay big dividends. Applying manure before seeding alfalfa may seem counter productive since alfalfa is not likely to benefit from any nitrogen in the manure, but manure also is rich in phosphorus, potassium, sulfur, and many micronutrients that alfalfa needs in large quantities.

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.
