Substitute fluid examinations for liquid manure

Pipeline Transportation of Liquid Manure

D to transportation costs, manures can be utilized for their fertilizer value only when the hauling distance is short. However, manure cannot be applied indefinitely to a limited land area close to the manure production site without creating problems of water pollution (Patni and Hore, 1978) and excessive nutrient and salt accumulation in the soil. Therefore, using manure for crop production on...

Evaluation methods on manure exposure from liquid manure injection tools

Rahman, S., Chen, Y., Zhang, Q. and Lobb, D. 2005. Evaluation methods on manure exposure from liquid manure injection tools. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 47: 6.9 6.16. Laboratory and field studies were conducted to explore evaluation methods on manure exposure (refer as to manure being not covered by soil, but exposed to the air) for liquid manure injection...

Inactivation of viruses in liquid manure.

The stability of some viruses and methods of virus inactivation in liquid manure are reviewed. The authors discuss experimental data on the stability of foot and mouth disease virus, classical swine fever virus, Aujeszky's disease virus, African swine fever virus, swine influenza virus, porcine paramyxovirus, bovine virus diarrhoea virus and transmissible gastroenteritis of pigs virus. Recommen...

Evaluation of a Mechanical Solid-liquid Separator for Swine Manure

Enhanced solid-liquid separation of dairy manure with natural flocculants.

The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...
