The Dangers of Farm Slurry and the Production of Slurry Gas
Slurry is created from cow manure and water and provides a fantastic, natural fertiliser that farmers can use to encourage the growth of grass and other crops. It is usually stored in a slurry tank or lagoon before it is applied to farmland as fertiliser. The dangers of working with slurry are well documented, as high amounts of gases can be released very quickly. How is farm slurry made? Waste ...

Acidification of slurry in barns, stores and during application: review of Danish research, trials and experience
Abstract Acidification is recognised as a method for reduction of ammonia volatilisation of manure. During the last two to three years acidification of slurry has become common in Denmark. In 2012 it has been estimated that about 11 % of all applied slurry in Denmark was acidified, and in 2013 it is expected that up to 20 % will be acidified. In all cases sulphuric acid is used for acidification, ...

Fertilizer Machine Manufacturer Introduces How to Produce Compound Fertilizer Granules
The common granulation processes of compound fertilizer include tower granulation, rotary drum granulation (NPK fertilizer production line), spray granulation and so on. As fertilizer machine manufacturer, let's introduce these production processes from the perspective of fertilizer production. 1. High tower granulation process is mainly used for the production of high concentration nitro ...

Principle and Process of Sweet Potato Starch Production
Sweet potato, also known as sweet potato, sweet potato, hawthorn, red glutinous rice, etc., is an excellent raw material for starch processing. The sweet potato starch production process is actually a physical separation process, which separates the cellulose, protein, inorganic salts and other substances in the raw materials from the starch. In the production process, starch is separated from ...

Ammonia sanitization of blackwater for safe use as fertilizer
Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris suum eggs, and treated with urea and/or lime in ...

A Bayesian network model for assessing natural estrogen fate and transport in a swine waste lagoon
Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine ...

Phosphorus distribution in untreated and composted solid fractions from slurry separation
Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

Effect of cattle slurry separation on greenhouse gas and Ammonia emissions during storage
Storage of cattle slurry leads to emissions of methane (CH4), nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2). On dairy farms, winter is the most critical period in terms of slurry storage due to cattle housing and slurry field application prohibition. Slurry treatment by separation results in reduced slurry dry matter content and has considerable potential to reduce gaseous ...

Pilot scale facility to determine gaseous emissions from livestock slurry during storage
Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

Cover crop effects on the fate of N following soil application of swine manure
Abstract Cereal grain cover crops increase surface cover, anchor corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] residues, increase infiltration, reduce both rill and interrill erosion, scavenge excess nutrients from the soil, and are easily obtained and inexpensive compared to other cover crop options. The use of cereal grain cover crops in fields where manure application occurs ...
