Carbon Cycling, Carbon Building

In this article I hope to provide some ideas concerning carbon cycling and how to effectively build soil carbonic organic matter. There seem to be three primary means by which we can increase a soil’s carbon content: carbon imports, carbon generation and carbon induction. Each of these possible methods can also offer other strengths to […]

Tractor Time Episode 10: Mark Shepard and Water Control on the Farm

In this week’s podcast, we are featuring Mark Shepard’s talk from the 2016 Eco-Ag annual conference in Omaha, Nebraska, where he spoke to a very full hall on his sustainable water practices he uses on his farms. It’s also the subject of his new book that we will be releasing later this fall, so stay […]

Ecological Economics

Herman Daly, Ph.D., is an ecological economist and professor emeritus at the University of Maryland’s School of Public Policy. His life’s work is to explore how massive-scale human activities can be ordered in ways that take into account the biosphere — “ecosystem services” in economic parlance — the life support systems on which everything depends.

New Livestock Integration

There is an old adage among livestock raisers that holds that blue ribbon-winning animals seldom make good parents, but generally make crackerjack grandparents. The one word answer for why this happens is, I believe, adaptation. A top Texas-bred bull, boar or ram whisked away to our Northern Missouri climes or someone else’s Maine environment is […]

Root System Architecture & Nitrogen Management

Researchers questioned whether current improved rice varieties are suitable for organic agriculture. Through an experiment focused on nitrogen use efficiency (organic and inorganic sources) and root system architecture, they concluded that varieties bred for high-nitrogen inputs may not be suitable for organic agriculture — reinforcing the need for varieties to be bred specifically for organic […]

Nitrogen can play a close second in the nutrient race, but in most soils phosphorus is the most limiting nutrient, often occurring in quantities a thousand times lower than other minerals.

Phosphorus: A Limited Resource

Soil is a living, breathing ecosystem. Just as you and I breathe, soil too re­spires, and we measure that respiration rate as an indicator of microbial activity in soil. While there are large, non-mi­croscopic organisms living in soil such as worms, insects and small mammals, none of them exist by the billions in just a […]
