Nitrogen Retention Study

This is interesting research on nitrogen retention in soils. My first question is, what is the impact to crop yields?

Getting the Dirt on Nitrogen in Agroecosystems

Results: Crop soils that are fed with biologically based nitrogen do a better job than synthetic fertilizers at retaining nitrogen, so less escapes into the air and water. Scientists from Pacific Northwest National Laboratory and Canada drew this conclusion after developing detailed nitrogen budgets—inputs, losses, and storage—of three agroecosystems in western Canada.
