American Society of Agronomy, Crop Science Society of America, Soil Science Society of America. October 21-25, 2012. Cincinnati, OH. Paper No. 147-11.Interpretive Summary:
                                Technical Abstract: Conservation Reserve Program (CRP) costs close to two billion dollars in federal funds every year; and yet, it is challenging to evaluate its effectiveness to assist the decision making process. Using a combination of physical properties and microbial indicators, we found that it is possible to make a general assessment of the soil ecosystem recovery based on evaluations of fields under CRP in comparison to adjacent wheat fields and fields containing native perennial vegetation that had been kept undisturbed for at least 20 years. Studies were conducted to compare these three ecosystems at two different sites and soil samples were taken twice a year for two consecutive years. Measurements included basic soil properties, aggregate stability, and fatty acid methyl ester (FAME) analysis. Using an aggregated value of multiple soil quality indicators, we found that the soil under CRP at one location had recovered approximately 10%, while the other had recovered approximately 50% when compared to the adjacent undisturbed soil ecosystem under native vegetation.
