Perspectives on Sustainability
Powering Planes through Arrested Anaerobic Digestion
Waste is not glamorous. Just look at the moldy pumpkin leftovers from Halloween and Thanksgiving (yes, there are still quite a few around my neighborhood!) and you know why so many of us prefer to not spend our time thinking about wastes. From an energy standpoint, however, waste contains a largely untapped reserve of resources that can be recycled into the products we utilize daily as consumers. When we recover these materials, we have fewer materials to deal with as waste – and also reduce our consumption of raw materials. So why is waste recovery not a typical component of our infrastructure?
Reflections on 2023
CSANR is an entity not easily explained in one fell swoop, but the range and breadth of projects we’ve undertaken throughout 2023 really showcase our primary goal: to find inspired solutions for the future of agriculture and the environment. Take a minute to reflect with us on 2023 and look forward to the developing projects and partnerships of 2024.
Nitrogen Fertilizer and Soil Organic Matter: What Does the Evidence Say?
Does synthetic nitrogen fertilizer burn up soil organic matter? Whether you are focused on soil health, soil sequestration, or soil carbon credits, this is an important question. The persistent claim is that synthetic N fertilizer can “burn” soil carbon by supercharging the soil microbes. This claim mainly arises from a 2007 research article from researchers at the University of Illinois (Khan et al., 2007; open access here) and has recently resurfaced in another article (Jesmin et al., 2021) and the resulting (flawed) media coverage. However, a single study is far from conclusive – so what does the broader scientific literature say? And what have we learned in the last few decades on the relationship between synthetic N and soil organic matter?
