Methane emissions reduced using gypsum in pilot‐scale dairy manure tanks

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Animal manure storage facilities are sources of greenhouse gas emissions in Canada, with the majority of emissions in the form of methane and nitrous oxide. This study was conducted to assess how effective adding gypsum powder to cow manure is at reducing the emissions of methane and nitrous oxide.

Soil Infiltration and Wetland Microcosm Treatment of Liquid Swine Manure [PDF]

, 2001
Management systems are needed to minimize water quality concerns associated with liquid swine manure from large swine production facilities. Experiments were conducted to investigate the removal of ammonium–N, nitrate–N, and total phosphorus from liquid ...

Swine Manure Nitrogen Availability and Carryover

, 2005
Swine manure is readily available in Iowa and is an excellent source of fertilizer for crops. Application rates are often based on the nitrogen (N) needs of the coming year’s crop. Producers often ask how much N is available the first year, and if any N carries over to subsequent years.

The role of natural savanna in maintaining dung beetle diversity and their ecosystem services in agricultural landscapes in the Brazilian Cerrado

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Low‐intensity management agriculture, such as organic agriculture, can benefit landscape permeability to key insects that provide ecosystem services to agriculture. Maintenance of natural savanna patches can increase the pool of species, benefiting local populations and the provision of their ecosystem services in agricultural landscapes.

Microbial Contamination Risks From Adjacent and Nearby Land: Evidence and Implications for Produce Safety

Journal of Food Science, Volume 91, Issue 1, January 2026.
ABSTRACT Consumers’ demand for fresh produce is rising due to dietary preferences and public health campaigns. Fresh produce is often consumed raw or minimally processed to retain nutrient content. If contaminated, fresh produce can become a vehicle for pathogen transmission and potentially cause outbreaks.

Belt separation system under slat in fattening pig housing: Effect of belt type and extraction frequency [PDF]

, 2010
The efficiency of manure separation by a conveyor belt under a partially slatted floor for fattening pigs was determined for two types of belts, a flat belt with an incline of up to 6° transversely and a concave belt with an incline of up to 1 ...

Yield From Iowa's First Commercial Miscanthus Fields: Implications of Spatial Variability for Productivity and Sustainability Beyond Research Plots

GCB Bioenergy, Volume 18, Issue 1, January 2026.
We developed, tested, and used a satellite remote sensing method to predict the productivity and profitability of sterile Miscanthus × giganteus. Using high‐resolution imagery and ground measurements from Iowa's first commercial miscanthus fields, we made a robust model that accurately estimated yield over 8 site‐years.

Advice on animal and public health risks of insects reared on former foodstuffs as raw material for animal feed

Food Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract In the coming decades, there is expected to be a sharply increased demand for dietary proteins for humans and animals. As a result, there is an increasing focus on reared insects as a new source of protein. According to the Ministry of Agriculture, Nature and Food Quality (LNV), the use of food chain residual flows such as former foodstuffs as
