Soil Fertility Paradigms Evaluated through Collaboration On-farm and On-station

A “paradigm” is a way of interpreting and making sense of the world. As such, our views on soil fertility are coherent with our interpretation of the scientific process and science institutions, and perhaps our feeling about the place of agriculture in the larger scheme of things. In agriculture today, two contradictory approaches to soil fertility uneasily coexist – the cation ratio paradigm (CR) and that referred to as “sufficient level of available nutrients” (SLAN)

Compost Rate Study at the Neely-Kinyon LTAR Site, 2002

Many farmers are interested in using manure and compost as sources of nutrients and microbial populations that are necessary for nutrient cycling in agroecosystems. Compost and synthetic fertilizer effects on corn yields and soil fertility have been compared in a Practical Farmers of Iowa cooperative trial at the Neely-Kinyon Farm since 1999
