Model Adaptation and Validation for Estimating Methane and Ammonia Emissions from Fattening Pig Houses: Effect of Manure Management System

Animals
This paper describes a model for the prediction of methane and ammonia emissions from fattening pig houses. This model was validated with continuous and discrete measurements using a reference method from two manure management systems (MMS): long storage

Landless peasants, soilless cultivation: British agricultural experimentation and intervention in post‐independence Iraq (1932–1958)

PLANTS, PEOPLE, PLANET, EarlyView.
‘Greening’ is often depicted as an inherently benevolent practice, turning arid stretches of land into arable and fertile plots. However, by considering a longer history of place and taking archival records into account, such transformations are rendered more complex and, often, more fraught.

Physicochemical Characterization of Broiler Poultry Litter from Commercial Broiler Poultry Operation in Semiarid Tropics of India

Agriculture
This study characterized the physicochemical properties of broiler poultry litter (BPL) produced from intensively reared commercial broilers that were collected from 110 commercial poultry farms at the end of the production cycle (sixth week).

Exchangeable lead (Pb) in lowland paddy soils of Sri Lanka as affected by the differences in agro‐climatic zones, soil orders, and water sources

PLANTS, PEOPLE, PLANET, EarlyView.
Lead (Pb) accumulation in the human body poses serious health risks. As rice is the staple food in Sri Lanka, with a high per capita intake (114 kg), there is a significant risk of Pb transfer through rice consumption. This study evaluated exchangeable Pb concentrations in soils and produced Pb distribution maps.

Resilience through diversity: The potential of modelling species and variety interactions to enhance resilience of production systems

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural production systems in the global North combine monocultures of specialised varieties and breeds with external interventions and inputs. Increasing the diversity of varieties, breeds and species may increase the system's resilience to external pressures through beneficial interactions.

MANURE VALUE AND LIVEWEIGHT SWINE DECISIONS [PDF]

Produced as a joint product, economic theory suggests that manure value could influence livestock management decisions such as herd size and optimal market weights. This study examines the concept of manure and its connection with optimal replacement age
