Use of cationic polymers to reduce pathogen levels during dairy manure separation

(View original article)  Various separation technologies are used to deal with the enormous amounts of animal waste that large livestock operations generate. When the recycled waste stream is land applied, it is essential to lower the pathogen load to safeguard the health of livestock and humans. We investigated whether cationic polymers, used as a flocculent in the solid/liquid separation process, could reduce the pathogen indicator load in the animal waste stream. The effects of low charge density cationic polyacrylamide (CPAM) and high charge density cationic polydicyandiamide (PDCD) were… Read More →

Calibration of Poultry Litter Applicators

Poultry litter has been used for many years in Texas as an alternative to commercial fertilizer. The poultry litter not only has the N (nitrogen), P (phosphorus), K (potassium) benefits, but it adds organic matter and all other essential nutrients to the soil. Proper precautions must be taken in order to prevent contamination of groundwater and runoff, while regulating soil P and N levels.
