There has been an increase in fertilizer use among farmers in the semi-arid Tigray region of Ethiopia during 2006-2015. Our household panel data covering nine years show that the average fertilizer adoption rate had increased from about 31% of plots in 2006 to almost 67% in 2015. Likewise,...

The Fertilising Products Regulation (EU) 2019/1009 lays down rules on the making available on the market of EU fertilising products. The European Commission may, under certain conditions, adopt delegated acts for new to add products derived from animal by-products within the meaning of...

Clean and efficient alternatives for sustainable treatment of pig farming wastes are a priority in suburban areas located at High Mountain ecosystems. Among these technologies are anaerobic and aerobic digestion with added microorganisms (bioaugmentation) or nutrients (biostimulation) as...

Studies on improving utilization, transportation, and storage of animal manure nutrients are critical to mitigating potential adverse environmental impacts of excess manure nutrients produced in regions with high concentrations of animal production. This study investigated the potential of...

Chicken manure (CM) is of a very complex and heterogeneous nature; thus, it is essential to analyze its properties to give it proper management. Direct use in agriculture as organic fertilizer is considered a popular treatment option for CM, which causes undesirable emissions of chemicals to the...

In this study, the effects of sawdust + hulls (CK) and rice straw stalks + mushroom waste (T1) as auxiliary materials on nitrogen as well as microbial structure in the composting process when composted with chicken manure were investigated. At the end of composting, the nitrogen loss of T1 was...

Faced with the worsening of climate issues, nations are directing efforts to build renewable energy matrices. Specifically with regard to biomass, it can contribute to the creation and strengthening of green competitive advantages in terms of cost for agricultural units. Strictly, swine biomass,...

Pyrolysis is a useful alternative to the current waste management practices. Manure biochars can be used as C-rich soil amendments, reducing the risk of greenhouse gas (GHG) emissions derived from unpyrolyzed manure decomposition. In this study, two manure biochars and their feedstock were used...

This study aimed to investigate long-term inhibition of chlortetracycline (CTC) antibiotics to anaerobic digestion (AD) of swine manure (SM). Two continuous-stirred tank reactors treating SM w/wo CTC spiking (3 mg/L) were operated for 900 days. The exposure level was determined according to...
