Researchers have evaluated strategies for efficiently estimating soil organic carbon in agricultural fields. Quantifying soil organic carbon stocks in agricultural fields is essential for developing ...

There is much more carbon stored in Earth’s soil than in its atmosphere. A significant portion of this soil carbon is in organic form (carbon bound to carbon), called soil organic carbon (SOC).

Lab tour shows how color variations in Midwest soils signal a need for customized nutrient management and seeding strategies.

Agricultural soil testing is critical to determining soil’s nutrient concentration and variability across your fields. It is ideal to test your fields’ soil at least every two to three years to inform ...

Soil testing begins with the homeowner, gardener, and farmer. The most critical step in soil testing is soil sample collection. Soil testing can help growers make informed decisions about fertilizer ...
