Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Anaerobic co-digestion of potato tuber and its industrial by-products with pig manure

, 2005
The possible use of potato tuber and its industrial by-products (potato stillage and potato peels) on farm-scale co-digestion with pig manure was evaluated in a laboratory study.

Experimental study on gas production optimization of pig manure and wheat straw under different pig manure levels

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In order to explore the optimal ratio of pig manure and wheat straw mixed fermentation process, the experiment controlled the temperature of the fermentation control fermentation process to 35 °C, the total mass of the fermentation liquid was 700 g, and the total soild (TS) was 8%.

Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union: characterization, safety, and efficacy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The re‐evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expressed no interest.

Dehydrated Mink Manure as a Protein Source for Growing Pigs [PDF]

Acta Veterinaria Scandinavica, 1978
The use of dehydrated mink manure as a protein source for growing pigs was studied by substituting 7.5 and 15 % (w/w) of the complete feed with manure and a corresponding amount of barley. The manure used had a poor feed value as compared to the values obtained earlier in digestibility tests in minks. The crude protein content was 21.3 %.

Manure Composting as a Strategy to Mitigate Antibiotic Resistance Dissemination in Agricultural Systems

Land Degradation &Development, EarlyView.
ABSTRACT Livestock manure is a valuable agricultural resource but may introduce antibiotic residues and antibiotic resistance genes (ARGs) into the environment. This review critically evaluates the fate of antibiotics and ARGs during manure composting and identifies the principal factors controlling their attenuation.

Reference life cycle assessment scenarios for manure management in the Baltic Sea Regions - An assessment covering six animal production, five BSR countries, and four manure types:Baltic Manure Report

, 2013
One major pre-condition for assessing a manure management technique in a whole system or LCA-approach is to define a reference system against which this technique can be assessed.

Business Model and Sustainable Development Goals for an Innovative Agricultural Waste Management: Distributed Biogas Production

Sustainable Development, EarlyView.
ABSTRACT Technological progress and population growth have increased global pork demand; leading to a rise of methane emission from pig farming, a key contributor to climate change. Anaerobic digestion offers a sustainable solution by converting manure into biogas.

Opportunities for Australia Amid China's Carbon‐Neutral Transition: Input–Output Approach With Analysis of Australian Renewable Potential

Sustainable Development, EarlyView.
ABSTRACT A major transformation in China's energy mix is underway as the country pursues carbon neutrality by 2060, posing significant structural challenges for Australia as a major exporter of carbon‐intensive resources. This study examines the economic impacts of China's decarbonisation on Australia by applying static and dynamic input–output (IO ...

Monitoring rodents' life history by body temperature and activity

Wildlife Biology, EarlyView.
European hamster populations are rapidly declining all over their distribution area. One of the suggested reasons is a strong and ongoing decrease in the reproductive output of about 77% since the nineteen twenties. The cause of this decline is, however, unknown.
