Review of existing and prototype manure treatment technologies to achieve phosphorus balance

Project: MLMMI 2010-05-L


  • Review existing manure treatment methods that are commercially available for all livestock types,
  • Develop an evaluation matrix to objectively evaluate the manure treatment technologies on a technical and economic basis. The matrix will include a scoring scheme based on successful implementations, energy input intensity, estimated capital and operating costs, complexity of operation, ability to handle fluctuations in manure composition and temperature, etc.,
  • Recommend potential manure treatment technologies for future evaluation in Manitoba�s conditions (climate, soil types, crop production practices, etc.) based on the results of the evaluation,
  • Develop a list of essential test methods and evaluation test methods to include in a test protocol for the technologies identified as being potentially suitable for Manitoba to allow an unbiased evaluation, and
  • Identify gaps in research, whether they are at the entire livestock operation level including optimization of barn configurations, development of novel manure treatment technologies, or implementation of existing waste treatment technologies into livestock operations. Research gaps will be identified according to their ability to be filled in either the short term or long term.
