Organic matter’s good for the soil. And also for crops and water. But it’s not all created equal. At next week’s annual conference of the Ohio Ecological Food and Farm Association, CFAES scientist Steve Culman will talk specifically about active organic matter: how it cycles rapidly, how it plays a big role in providing nutrients to crops, how soil tests measure it, what CFAES research is learning about it, and how you can enroll to have your soil tested for free in an ongoing study. “Active Organic Matter in Your Soil,” Session V, 1:30 to 3 p.m., Saturday, Feb. 11.
