Anaerobically Digested Manures

This webcast shares information on: monitoring protocols for anaerobic digesters, fate of nitrogen from manure after it has been anaerobically digested (AD), effect of AD manure on grass yield and nitrogen uptake, the fate of bacteria from manure after it has been AD, and the fate of bacteria after land application of AD manure. This presentation was originally broadcast on May 21, 2011. More… Continue reading “Anaerobically Digested Manures”

Evaluating Manure Treatment Through Farm Pilot Project Coordination

Manure treatment technologies are not one size fits all. Wouldn’t it be great if we could learn from others that have implemented many different farm scale technologies? Fortunately, the Farm Pilot Project Coordination, Inc. has a wealth of information related to its 40 projects. This presentation was originally broadcast on August 21, 2009. More… Continue reading “Evaluating Manure Treatment Through Farm Pilot Project Coordination”

Overview of Alternative Manure Treatments, Matching the Treatment to the Environmental Concern

Manure treatment systems address a wide variety of environmental concerns. Whether adding a new component to an existing system or starting from scratch, it is possible to combine different technologies in ways that best fit the needs of the operation and help minimize the impact on neighbors and the environment. The presenter for this webcast is Robert Burns, Iowa State University. This presentation was originally broadcast on October 19, 2007. More… Continue reading “Overview of Alternative Manure Treatments, Matching the Treatment to the Environmental Concern”
