Biogas slurry and residue contaminated with antibiotics are widely used as fertilizers in vegetable crop planting. However, their impact on the spreading of antibiotic resistance genes (ARGs) in vegetable fields is still largely unknown. In the present study, antibiotic resistant bacteria (ARB), ARG …
The biogas slurry originated from the pig manure anaerobic fermentation tank on the Shanghai farm and was stored and precipitated in the storage pool. The supernatant of the biogas slurry entered the paddy field through the cement irrigation ditch with irrigation water. The total water volume was also consistent for each treatment.
The application of biogas slurry as an organic fertilizer is a promising method for utilizing breeding manure wastewater. At present, the impact of biogas slurry on the properties of organic matter in soil is not clear. In this study, a pot experiment in which chemical fertilizers were replaced with …
Bio-slurry is a waste of biogas with various benefits. Even though it is called dregs, bio-slurry still has many nutrients that are useful for agriculture and can also be used as a natural fertilizer. Just like biogas, the composition of bio-slurry is a combination of manure and water. To become bio-slurry, it has passed the process in the tank ...
Biogas fertilizer has the characteristics of a wide source of raw materials, low cost, full nutrients, long efficiency, and soil improvement. Biogas slurry is a quick-acting fertilizer, which is suitable for vegetable fields or dry land with irrigated conditions for topdressing.
Biogas Slurry Solid Fertilizer Technical Difficulties and Solutions The first technical difficulty of biogas waste fertilizer production is the fermentation effect. Using dry-wet method, water content in biogas residues can rapidly meet the requirements. In the process of fermentation, use biological method to make it hest up and then achieve ...
Biogas slurry in fish culture by S.D. Tripathi and B. Karma Cow dung is commonly used as a fertilizer for fishponds in India but fish production is limited to 1 500-2 000 kg/ha.
Biogas slurry is an anaerobic digested organic material released as byproduct from the biogas plant, which has been used as a fertilizer in agricultural production to maintain soil fertility, enhance crop production, and reduce the probability of diseases (Wang et al., 2018).
Bio-slurry untuk pertanian yang lebih berkelanjutan. Biogas adalah energi terbarukan yang membantu masyarakat agar mampu mengakses energi hemat, ramah lingkungan, dan bersih. Selain itu, biogas juga merupakan salah satu penghubung rantai keberlanjutan lingkungan yaitu dengan cara mengubah kotoran ternak–yang menyumbang gas emisi ke atmosfer–menjadi energi sehari-hari hingga …
All materials in contact with the manure or biogas should be corrosion resistant. For instance, PVC plastic was used for the slurry handling pipes in the Penn State digester. The design should incorporate alternative methods of moving slurry or biogas through the system. A blocked pipe could result in backed up slurry spilling from the digester.
Biogas slurry is a by-product of anaerobic digestion that pro-. duced from biogas plant and also produces biogas (combustible. methane gas) that is used for cooking, lighting and running en ...
Biogas slurry is a secondary product produced by anaerobic fermentation of bio-materials, which has been widely used as a fertilizer in agricultural production. Biogas slurry is not only an environmentally friendly organic fertilizer, but …
Study area and biogas slurry collection. A field experiment was established in April 2013 at the Ecological Experimental Station of Red Soil, Chinese Academy of Sciences, which is located in Yujiang County, Jiangxi Province, southern China (28°12′N, 116.5°5′E), with a peanut (Arachis hypogaea)—fallow cropping rotation system.The climate is tropical and subtropical monsoon with …
Biogas slurry and residue can be used as good fertilizers due to their high contents of organic matter and nutrients . However, whether long-term application of biogas slurry and residue would impact the abundance of ARGs and mobile genetic elements in vegetable soil remains unknown and further research should be conducted on this topic.
