Does plant biomass manipulation in static chambers affect nitrous oxide emissions from soils?

This study seeks to understand how or whether plant biomass manipulation affects N2O emissions estimated as part of chamber-based GHG measurements by examining the effects of biomass cutting vs. folding on N2O emissions in perennial switchgrass and alfalfa cropping systems.

Greenhouse Gas Equivalencies Calculator

Did you ever wonder what reducing carbon dioxide (CO2) emissions by 1 million metric tons means in everyday terms? The greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants. This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.

Got pasture? How grazing intensity affects the environmental impacts of dairy systems

A Wisconsin dairy farm was modeled to evaluate greenhouse gas emissions, net energy intensity, and land use of confined dairy systems with increasing levels of pasture in the diet. Enteric methane was the greatest contributor to GHG emissions, and the production of crops was the most energy-intense process.
