A Pilot Program to Assist CAFOs in Using Weather Data to Minimize Manure Management Risk
This paper summarizes a pilot project to disseminate site specific weather information that has been processed to estimate field runoff potential of land applied manure. Preliminary feedback indicate the program has value but that additional information is needed to understand how farmers use weather information to make decisions within the regulatory constraints they face.Environmental Economics and Policy,

Reconciling transport models across scales: the role of volume exclusion
Diffusive transport is a universal phenomenon, throughout both biological and
physical sciences, and models of diffusion are routinely used to interrogate
diffusion-driven processes. However, most models neglect to take into account
the role of volume exclusion, which can significantly alter diffusive
transport, particularly within biological systems where the diffusing particles
might occupy a significant fraction of the available space. In this work we use
a random walk approach to provide a means to reconcile models that incorporate
crowding effects on different spatial scales. Our work demonstrates that
coarse-grained models incorporating simplified descriptions of excluded volume
can be used in many circumstances, but that care must be taken in pushing the
coarse-graining process too far
