Two producers inspect the soil in a no-till field early in the growing season.

Managing Soil for Carbon Storage

Did you know that adopting soil health principles can lead to increased soil carbon concentrations? Learn about some recent studies in South Dakota that evaluated the potential of land management activities to increase soil carbon.

Crop Residue, Cover Crops Impact on Soil Health Parameters

Interest in no-till and cover crops has been on the rise among South Dakota crop producers. In 2019, half of South Dakota crop ground was under no-till management and about 900,000 acres were planted to cover crops.

Seven Grams of Fertilizer Is All It Takes: Growing Optimal Corn in South Dakota

Have we really asked how much fertilizer is really takes to grow a decent corn crop? Learn some important considerations for fertilizing corn and improving long-term soil health and fertility.

Does the GREET Carbon Model Address Soil Health Principles?

Learn how the recent Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) production model lines up with the Five Soil Health Principles.

Two researchers analyzing soil in a no-till field with cover crops growing throughout.

Does the COMET Carbon Model Address Soil Health Principles?

The COMET-Farm model, developed by USDA/NRCS and Colorado State University, is a whole farm and ranch carbon and greenhouse gas accounting system. Learn how it addresses the Five Soil Health Principles.

Two rows of corn at V5 leaf growth stage looking down from above. Between the corn rows there are 3 separate cotton strips placed on the soil surface just before burial in a 2-inch-deep trench. The cotton strips are numbered for their identification after recovery at three different dates.

Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity in the Field

Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.

Biological Agronomy

Biological agronomy is an adaptive soil management system used to build soil microbiology through intensive regenerative practices that increase carbon and nutrient availability for profitable crop production.
