(Radio Iowa) – An Iowa-based group that aims to help farmers practice a form of agriculture that benefits both the land and the people is working to recruit new members, especially in northwest Iowa. Practical Farmers of Iowa agronomist Sarah Carlson says the issue of water quality is one key area where they’ve determined they can start discussions with potential members.

Carlson says crop rotation, cover crops, and grazing all help to reduce nitrate loss and reduce erosion, which are two of the biggest water pollutants. Some of the older concepts are still very much workable, especially with precision agriculture, which Carlson says has led to a new term, precision conservation.

She says P-F-I works with farmers to diagnose trouble spots, get them out of production and into some sort of conservation project.
