The current trend regarding large-scale animal farming and fertilizer use is toward clarification and tightening the regulations; thus, new technologies for manure processing are needed. In 2015, Chirag Mehta and coworkers presented a general scheme for nutrient recovery from waste streams (Mehta et ...
If you live in or near farm land, there's a good chance that you've had to tolerate the incredibly putrid smell of liquid aged cow manure. It's a potent smell that can drift for miles and it's almost always spread on farm land during sunny, hot weather,
Efficiency and productivity analysis of vegetable farming within root and tuber-based systems in the humid tropics of Cameroon The study analyzes the technical efficiency of vegetable farmers in root and tuber-based farming systems within selected sites of the humid tropics of Came...

Agricultural residues (manure and straws) have been used, as a feedstock of choice for biogas production through AD [37]. By using manure as feedstock in AD, the bulk of waste from animal husbandry and dairy farming can be converted to a renewable energy while at the same time ‘cleaning ...
Antibiotics resistant genes (ARGs) are frequently detected in different media, such as wastewater, sewage sludge, and livestock manure. ARGs have been evid
The results showed that under the same experimental conditions, the furrow resistance of the bionic coupled furrow opener was obviously lower than that of the common flat furrow opener, and it can be used for high-efficiency agricultural farming. Ahmad Fiaz et al. [7] made discrete element ...
During the flooding period before mid-season drainage, flooding water depth was kept around 3–5 cm by irrigating with water from a farm pond near the experiment station and draining surface water via a drain outlet near the soil surface (mainly at the time of high water level after a ...
Introduction Swine farming forms a major part of the agricultural portfolio in many countries. For example, in the United States alone, swine farmers produced about 66 million pigs (with a value of approximately $22.5 billion), which in turn produced about 73 million tons of manure each year ...

RBC produced for this study was not an important source of potentially toxic elements, probably due to the more controlled diet of domestic rabbits compared with large-scale farming. However, this implication is important for managing the risk related to heavy metal transfer from feed to manure ...
