Farmers, ranchers, and foresters are facing increasing challenges related to changing climate and weather, manifested in rising average temperatures, more frequent extreme rainfall events, extended drought, and heat waves. These changes are also impacting pest abundance and distribution, creating new pest problems and straining current pest management options and decision-making. Key factors for U.S. agriculture and producer resilience in tackling new environmental and pest challenges lie in the ability of producers to apply effective, economical integrated pest management (IPM) approaches and in support for research and development of new and renewed IPM tactics and systems to meet 21st century needs.

Soil health has long been recognized as important. There are many proven practices known to build and maintain soil health, but there are other practices that are suspect. Measuring soil health is happening, but it is an immature science. Will we find that the existing soil health tests are meaningful? Will new methods be developed? What will the collective efforts of those implementing the aforementioned practices be upon yields? Crop quality? Carbon sequestration equilibrium? Soil and environment sustainability? And, of vital importance, what is the financial sustainability for growers and society?

This is the second article in our series on soil health and greenhouse gas emissions on U.S. dairies associated with crop production. This article will focus on the first objective of the Dairy Soil and Water Regeneration (DSWR) project, which is to benchmark soil health and soil carbon stocks in dairy forage production systems.

While a comprehensive economic analysis of cover crops accounting for all soil ecosystem services from cover crops is lacking, the available studies indicate that cover crops have potential to provide positive net returns if biomass production is sufficient. Among the opportunities to generate positive economic outcomes from cover crops include grazing and harvesting cover crops, savings on herbicides and fertilizers, carbon credits, and monetization of soil ecosystem services.

Cereal rye, as a fall-planted and winter-grown cover crop, offers many benefits. It tolerates both frigid winter temperatures and warm springs. It also tolerates both the wet conditions and drought. It reduces soil erosion, enhances soil organic matter, improves soil water retention, and reduces nutrient leaching. But, it’s not a panacea, of course. This article will discuss some of the benefits, challenges, and considerations of using cereal rye as a cover crop.
