However, the Labile-P in raw manures ranging from 64.67% to 81.10%, indicated that AD could reduce the pollution risk caused by the overuse of high Labile-P animal manure as fertilizer. Metal ions had a significant influence on P transformation because of their ability to combine with PO 4 3− /HPO 4 2−.

Dairies in Europe are major economic drivers in rural areas, but they produce significant waste from cleaning and processing. Wastewater and milk residue, which are typically disposed of, are now being turned into new products such as phosphate-rich fertiliser and bioplastics. The EU produced 172.2 ...
And for as many different types of soils as there are, there are even more fertilizers available to amend them. Two of the most common fertilizers gardeners utilize are manure and compost. But when you compare manure vs. compost, what's the difference between the two? Manure is animal dung, usually from horses, cows, and chickens.

These differences should be taken into account when exploring the potential of Salix-based biogas production systems, as they can have a significant influence on system parameters and performance. This study analyzed a biomethane production system using co-digestion of pre-treated Salix biomass with dairy manure.
The hot arid climate, scarce water resources and waste collection methods limit technology choices for treating manure. Six years ago Chaves County, New Mexico, dry lot dairy producers formed the Pecos Valley Biomass Cooperative, Inc.
