Anaerobic digestion (AD) for biogas production leads to several changes in the composition
of the resulting digestates compared to the original feedstock (ammonia content, p H, carbon …

Research on nitrogen (N) mineralization from organic residues is important to understand N
cycling in soils. Here we review research on factors controlling net N mineralization as well …

In order to apply manure or compost to fulfill the nutrient requirements of a crop, knowledge
of the amount of nutrients mineralized following application is needed. Nutrient …

To manage nitrogen (N) efficiently, organic growers must be able to predict the amount and
timing of plant‐available N from organic amendments. In this study, we measured N …

Recent evidence suggests that oxygen limitations are a critical regulator of soil organic
matter mineralization rates, even within seemingly well-drained upland soils. Oxygen …

Proper estimation of the nitrogen (N) content of poultry manure and proper manure handling
are necessary to ensure that application rates minimize emissions from the manure and …

Recent adoption of national rules for organic crop production have stimulated greater
interest in meeting crop N needs using manures, composts, and other organic materials …

Understanding the dynamics of N forms applied as manure is germane for appropriate rate
and timing of applications of manure. Manure characterization and laboratory incubation …

Accurate estimation of animal manure nitrogen (N) availability is required to maximize crop
N use efficiency and reduce environmental N losses. Many field and laboratory experiments …

The influence of bulking agents on organic matter (OM) stability and nitrogen (N) availability
in sludge composts was investigated. Seven mixtures were composted over a 12-week …
