What’s a responsible farmer to do? Manure injection is an important soil management practice that reduces the chance of manure runoff. But recent studies by Carol Adair and colleagues at the University of Vermont show manure injection can increase the release of harmful greenhouse gases.
We often “flush it and forget it” when it comes to waste from toilets and sinks. However, it’s important to be able to track this wastewater to ensure it doesn’t end up in unwanted places. Tracing where this water ends up is hard to measure: What’s something found in all wastewater that will allow us to account for all of it? The answer, of all things, is artificial sweeteners.
Consumption of crops is outgrowing the production of crops around the world. Malnutrition and starvation are major international issues. Fertilizers can help growers increase food production, but how? The January 22 Sustainable, Secure Food blog post explains how fertilizers help growers provide nutritious, affordable food for the world’s growing population.
