Field microplot estimates of soil N mineralization for manured and non-manured soils

Creator:

Sullivan, Dan M., Cogger, Craig G., Bary, Andrew I., and Myhre, Elizabeth

Abstract:

Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...

Developing Extension guidance for management effects on ammonia loss: a computer simulation modeling approach

Creator:

Sullivan, Dan M.

Abstract:

Computer simulation models provide insight into ammonia loss processes and the sensitivity of ammonia loss predictions to environmental and management variables. As an example of how a simple computer simulation model can inform the Extension guideline development process, the ALFAM (Ammonia Volatilization from Field-Applied Animal Slurry) model was used to...
