Computer Programs That Calculate Manure Application Rates

Autor: Rodney B. Thompson, D. Morse, K. A. Kelling, L. E. Lanyon

Publikováno v: Scopus-Elsevier

Decision support systems (DSSs) operated on personal computers are a convenient means to calculate application rates of livestock manures that meet crop nutrient requirements and avoid excessive nutrient applications. Twelve DSSs that can be used to

Comparison of estimates of first-year dairy manure nitrogen availability or recovery using nitrogen-15 and other techniques

Autor: G R, Muñoz, K A, Kelling, J M, Powell, P E, Speth

Publikováno v: Journal of environmental quality. 33(2)

Measurements of dairy manure nutrient availability to crops typically show great variability. Approaches that are more accurate are needed to improve manure management and reduce nutrient loss to the environment. In this study, we compared direct (15
