Understanding Soil Carbon Dynamics

Carbon is an often overlooked, but very important com­ponent of the soil. We know how to manage nitrogen, phos­phorus and potassium for maximum production, and that micronutrients play a critical role in crop yield and disease resistance. Deficiencies can usually be corrected relatively quickly through the addition of soil or foliar fertilizer ap­plications. While soil […]

Building the Microbial Bridge to Support Nutrient Availability

It’s strange to think that plants have a hard time getting enough nutrients when soils are composed of around 45 percent minerals. Many of those minerals are the nutrients plants need to grow, photosynthesize, flower, pollinate and produce fruit or seeds. Although soil is a huge bank of minerals, most of those minerals are not […]

North Dakota farmer Gabe Brown stands among his crops

Gabe Brown on Ecosystem Stewardship

North Dakota farmer and rancher Gabe Brown stands at the forefront of the regenerative agriculture movement. He is perhaps best known for popularizing the concept of cover crop cocktails as a key strategy for jumpstarting soil health and nourishing soil biology, but that’s only one of his many contributions. To his life work, Brown brings […]
