Carbon sequestration is coming up often in the farm press as we learn about another stream of farm income rising from our land-management practices. Why is adding carbon to the soil worth money to farmers, you might ask? Read more in this article from the Culpeper Star-Exponent (Culpeper, Virginia).

The USDA is looking to create a set of pilot projects that provides incentives to implement climate smart conservation practices on working lands and to quantify and monitor the carbon and greenhouse gases associated with those practices. The pilot projects could even expand or develop new and additional markets.

According to a new study published by scientists at the University of Massachusetts-Amherst in the journal Proceedings of the National Academy of Sciences, more than a third of farmland in the U.S. Corn Belt has completely lost its carbon-rich topsoil to erosion.

The carbon-to-nitrogen ratio is a critical number to know when planning for both cover crops and cash crops, according to Pennsylvania cover crop expert Steve Groff. The C:N ratio affects decomposition rates for crop residues and impacts nitrogen cycling as well. Understanding the C:N ratio helps growers be better managers in the context of overall soil health and fertilizer use. Groff shares why this often-overlooked aspect is critical to making good decisions when growing covers.

Recent research published in the Soil Science Society of America Journal compared farming systems that received different amounts and types of organic matter sourced from compost and cover crops. The results reiterated that soil enzyme activity confirms the importance of frequent cover cropping in tillage-intensive organic vegetable production.
