Managing Manure as a Fertilizer for Prairie Agriculture
Posted in: Environment by admin on January 1, 2000 | No Comments
All jurisdictions recommend manure management plans, with some requiring formal submission. This is because all manure is not created equal. Nutrient compositions vary greatly in both solid and liquid manure and are a function of livestock type, age, type of feed, composition of feed, rations climate, the presence of bedding, manure storage and manure handling. Therefore manure should be tested annually. For liquid manure (<4% solids), agitated samples should be collected as close to time of application as possible to establish nutrient levels. Solid manure (4-20% solids) samples can be taken prior to application from holding areas or manure piles. If we consider manure as a fertilizer, crop selection is unlimited. The only requirement is to balance manure nutrients against crop uptakes and residual soil N. Soil test and fertilizer recommendations should be used to calculate annual manure application rates. All fertilizers should be managed to reduce nutrient losses that occur from harvest, erosion, volatilization and denitrification. Effective manure management practices during storage, handling and application and time of application will minimize losses. Managing manure to minimize losses will indirectly address other issues like air quality, water quality, odour and human health.

Demonstration of the Performance of a Three-Stage Waste Treatment Technology. Odour Treatment Through Solids Separation with Aerobic and Anaerobic Digestion
Posted in: Environment by admin on | No Comments
The project involved evaluation of a Taiwanese three-stage hog manure treatment technology under Canadian conditions. To do so, a pilot plant treatment system was designed and built. The process involves passing the manure through a solid-liquid separator to remove the larger solids; anaerobic digestion of the liquid fraction; followed by aerobic treatment. The plant did not achieve treatment levels that would permit discharge to surface waters, as is the case in Taiwan. But was very effective for flushing the barn and produced a noticeable improvement in barn air quality. This was likely due to the differences in operational temperature between Taiwan (greater than 25A

PAMI builds tanker truck injector for research and demonstration
Posted in: Prairie Swine Centre by admin on | No Comments
The objective of this project was to develop a liquid manure application system to efficiently supply swine manure research and demonstration sites throughout Saskatchewan. The best option was to develop a truck based system with a vacuum/pressure tank capable of travelling long distances. A 1994 Mack semi-trailer truck with the fifth wheel removed was customized for liquid manure injection for both low and high disturbance plots. The truck injector system was completed in the fall of 2000 and is now used for all swine manure plot research conducted by PAMI in Saskatchewan. Further discussion with Sask Pork is underway regarding expansion of this project to swine manure application demonstrations in addition to research activities.
