Quantifying the mitigating effect of organic matter on heavy metal availability in soils with different manure applications: A geochemical modelling study

Ecotoxicology and Environmental Safety
Manure is one of the main sources of heavy metal (HM) pollution on farmlands. It has become the focus of global ecological research because of its potential threat to human health and the sustainability of food systems.

Functional relationship of particulate matter (PM) emissions, animal species, and moisture content during manure application

Environment International, 2020
Livestock manure is recycled to agricultural land as organic fertilizer. Due to the extensive usage of antibiotics in conventional animal farming, antibiotic-resistant bacteria are highly prevalent in feces and manure.

Hotspots and bottlenecks for the enhancement of the environmental sustainability of pig systems, with emphasis on European pig systems

Porcine Health Management, 2023
Although pig systems start from a favourable baseline of environmental impact compared to other livestock systems, there is still scope to reduce their emissions and further mitigate associated impacts, especially in relation to nitrogen and phosphorous ...

Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

Natural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Production of biochar derived from guinea pig manure as a soil amendment in high Andean and coastal acidic soils in Peru: agronomic potential and cost analysis for sustainable circularity

Frontiers in Agronomy
IntroductionThe valorization of local resources, such as guinea pig manure, allows traditional inputs to be transformed into more stable products with higher added value, such as biochar, rather than being used as raw manure.MethodsThis study evaluated ...

Phosphorus accumulation and pollution potential in a hapludult fertilized with pig manure

Revista Brasileira de Ciência do Solo, 2012
Successive applications of pig litter to the soil surface can increase the phosphorus (P) content and alter its adsorption, promoting P transfer to surface or subsurface waters.

Optimizing Larval Density for Efficient Bioconversion of Swine Manure Using Black Soldier Fly (Hermetia illucens; Diptera: Stratiomyidae) Larvae

Journal of Applied Entomology, EarlyView.
ABSTRACT Swine manure management poses significant environmental challenges, and black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae) larvae, offer a sustainable alternative by converting manure into insect biomass while reducing waste volume.
