How does that manure get in our water?

That green scum on the lake in August? There's a real chance it started on a farm. Kirsten Workman, Cornell's nutrient management and environmental sustainability specialist, joins Research Matters to explain how manure — a valuable nutrient package when it stays put — becomes a public health hazard when it doesn't. From phosphorus indexes to injection versus spraying to the runoff forecast tool she built, this is a close look at the unglamorous, high-stakes science of keeping farm nutrients where they belong: in the soil, not the water supply.
