2009 Manure Phosphorus Balance Workshop
UM NCLE multidisciplinary researchers engage in whole systems manure P balance research in three key areas plus economic investigations:
Whole systems multidisciplinary projects in place for pigs,
dairy and beef. Read the summary article in the Jan/Feb Newsletter
Feed management: feed ingredients, processing, diet formulation, feeding practices (e.g. phase feeding), etc.
Kees Plaizier (dairy), Martin Nyachoti (swine), Juan Carlos Rodriguez-Lecompte (poultry), Jim House (poultry) Kim Ominski (beef)
Field management: manure form/source and (long term) in-field application practices; rotation management; P cycling, movement and plant uptake of manure P (raw, treated, processed) in agricultural soil
Don Flaten, Mario Tenuta, Wole Akinremi, Francis Zvomuya
Manure management: processing and/or treatment of liquid and solid manure; manure storage
Nazim Cicek (liquid manure treatment/processing), Francis Zvomuya (liquid manure treatment, agronomic use of manure treatment end products)
Economics: Derek Brewin
Feed Management
Swine:
Project leader Martin Nyachoti
Dietary manipulation strategies and nutrient management planning to minimize N and P in manure while maintaining pig growth and health
- Nutrient Management Planning for Sow Operations Using Extant and New Feed Consumption Models and Manure Analysis. MLMMI funded. Read the report
- Whole Farm Nutrient Balance: evaluating diets containing zero tannin faba beans and DDGS for the whole pig production and manure management system. Collaboration with the Puratone Corporation. Funded by MRAC, MPGA and Farmer's Edge. Read the summary article in the July/August Newsletter
Cattle:
Project leader Kees Plaizier
New – (Dairy) Reducing whole-farm surpluses of phosphorus and potassium in intensive livestock operations. DFM, MRAC and MLMMI funded. Read the summary article in the Nov/Dec Newsletter
Project leader Kim Ominski
(Beef) Nutrient utilization and nutrient excretion from cattle during the overwintering period: Implications for supplementation of low quality forage diets with DDGS. MCPA, BCRC, MRAC, ARDI, MITACS, Greencover funded.
Poultry:
Project leader Juan Carlos Rodriguez-Lecompte
Inclusion of DDGs in poultry diets and manure P content: Implications for feeding strategies to decrease P loading. MLMMI funded
Project leaders Jim House and Ermias Kebreab
Development of Manitoba-based computer models for nutrient management in the laying hen industry: strategies to reduce phosphorus excretion. MEF and MRAC funded.
Field Management
La Broquerie Long Term Pasture and Manure Management Study (hog manure on grasslands)
Projects leader Mario Tenuta
Long term fate of manure nutrients in soil and groundwater at the La Broquerie site. This long term study has been in place for 6 years. What were the findings? Visit the La Broquerie Project website for more on this systems-based project.
Proposed next phase - Adaptation of integrated livestock systems to high soil test phosphorus in Southeastern Manitoba: manure, forage, soil and whole system-level management
NCLE Long Term Manure and Crop Management Study
Projects leader Don Flaten
Long term nutrient cycling under different livestock manure and crop management scenarios: Nutrient movement (from solid dairy and liquid pig manure and synthetic fertilizer) and crop uptake over time under annual and annual/perennial cropping rotations. ARDI funded.
Nutrient release from solid cattle manure in a perennial forage system
Manure Behavior in Soil
Projects leader Wole Akinremi
Downward movement of nutrients for different manure sources, soil type and crop management scenarios. MLMMI, ARDI and SDIF funded.
Indirect implications for P Balance: N release from solid cattle manure with different C:N ratios: Developing a calculator for estimating the fertilizer equivalence of different manures
Manure Management & Treatment
Project leader Nazim Cicek
Literature Review: Evaluation of the opportunity for manure treatment/processing technologies to achieve manure phosphorus balance in Manitoba. MLMMI funded. Read the review
Project leader Francis Zvomuya
New - Assessing the efficacy of chemically-enhanced solid-liquid separation for management of phosphorus in hog manure. MLMMI funded
Value Added Treatment Products
Project leaderNazim Cicek
Reclaiming phosphorus from liquid pig manure: Precipitation of P as struvite (MgNH4PO4) from liquid pig manure. ARDI funded. Read the ARDI article and watch the video.
Proposed next phase- Opportunities for struvite recovery from covered and open lagoons at commercial scale operations in Manitoba.
Projects leader Francis Zvomuya
Agronomic suitability of manure processing/treatment products for use as fertilizer
- New - Anaerobically digested solid beef feedlot manure (N2O emissions, nutrient availability and release – N, P). Also temperature effects on nutrient availability. Lab scale comparison with fresh manure, digested manure, pelletized digested manure and synthetic N+P. Collaboration with Lethbridge where are running field trials.
- Future – precipitated struvite and pure struvite evaluation in MB soils
- Future – separated solids from s/l separation evaluation in MB soils
Economics
Project leader Derek Brewin
Completed (2010) - A regional dynamic assessment of emerging manure management in Manitoba.
