Developing responsible, ecologically sound
The ever-growing prevalence of livestock on the Prairies in higher concentrations presents challenges of responsible, ecologically sound manure-management practices. PAMI has developed expertise in researching alternative waste-management technologies.
PAMI, in cooperation with the University of Saskatchewan, has been conducting long-term swine-manure research at various Saskatchewan locations for over seven years. Manure is injected into the soil using several different methods, applied at various times, and using different rates of application. The objective is to develop sustainable manure application technology to optimize the agronomic performance of swine manure while protecting the environment.
A Pioneer in Low-disturbance Manure Injection
PAMI pioneered the use of low-disturbance manure injection in western Canada, and this application method has now been commercially accepted.
To support the initiative, PAMI developed a manure injection truck to support the liquid swine manure research. The truck was custom built to accurately apply a wide range of application rates using low- or high-disturbance injection.
Besides swine-manure research, PAMI is also conducting agronomic research with feedlot manure, poultry manure and digester effluent.
Precision solid manure applicator prototype
In collaboration with the University of Saskatchewan, PAMI developed a prototype precision solid-manure applicator to improve the uniformity of distribution of solid manure. PAMI also modified the prototype to allow for sub-surface application of solid manure. Studies to evaluate the environmental benefits of sub-surface application of solid manure were conducted and a two year study to evaluate the effect of improving the uniformity of distribution is underway.
