Efficacy Evaluation of Civil-Works Mud as Soil Matrix Modified by Organic Amendments

Agriculture
Converting civil-works mud (CWM) into soil matrix is a significant method for resource utilization, effectively mitigating CWM accumulation. In this study, CWM was utilized as a soil matrix and modified with three organic materials: pig manure, biochar ...

BIO-ENERGY FROM PIG'S MANURE

Poljoprivreda, 2004
After settling, in the sample of pig’s manure, before and after anaerobic fermentation different layers appear: foam, fine colloids, floating particle-colloids and sediment-rude particles. During the anaerobic treatment it being favourable for maintaining the anaerobic fermentation was examined.

Does the regulation of manure land application work against agglomeration economies? Theory and evidence from the French hog sector [PDF]

The well-known increase in the geographical concentration of hog production suggests the presence of agglomeration economies related to spatial spillovers and inter-dependencies among industries. In this paper, we examine whether the restrictions on land

Ruminant versus non-ruminant manure composting: carbon-to-nitrogen ratio and associated physicochemical traits impact divergent pollutant emissions

Frontiers in Microbiology
Composting can convert livestock manure into valuable fertilizer, but the relationships between manure type, which essentially reflects differences in carbon-to-nitrogen ratio (C/N) and other associated physical properties, and pollutant gas emissions ...
