Inherent P Supplying Ability of Organically Managed Soils

Prepared by the University of Saskatchewan, Funded by the Agriculture Development Fund

Principal Investigator Dr. J.D Knight’s  overall objective of this study was to perform soil-based and plant-based
measurements of nutrient availability on soils from organic and conventional farms to identify which measurements are best suited for each system and identify which measurements best represent the overall fertility of the soil for crop growth.

Intercropping Field Pea Varieties for Organic Production

Prepared by the University of Saskatchewan, Funded by the Agriculture Development Fund

Researchers Lena Syrovy and Steven Shirtliffe: Semi-leafless field pea varieties which have tendrils instead of auxiliary leafs have less lodging than leafed peas. Because of this semi-leafless pea varieties usually have reduced plant diseases, higher yields and much easier harvestability. However, because of reduced light interception, semi-leafless peas are usually less competitive with weeds than leafed peas. Varietal mixtures of leafed and semi-leafless field pea varieties may offer the benefits of both semi-leafless and leafed peas. However this hypothesis has not been tested. The overall objective of this research was to establish the optimum ratio of leafed and semi-leafless field pea
varietal mixtures for organic and conventional crop production.

Evaluation of Novel Crops as Green Manures in Organic Agriculture

Prepared by the University of Saskatchewan, funded by the Agriculture Development Fund

Principle Investigator Dr. JD Knight expands on research conducted by Dr. Steve Shirtliffe (Saskatchewan Ministry of Agriculture Organic Chair, Dept. Plant Science, U of S). Dr. Shirtliffe’s group is evaluating methods of termination and timing of termination of field pea (cv. 40-10) and a small seeded faba bean (cv. CDC SSNS1) on productivity and weed growth in organic systems. A main focus of the project is to evaluate the effectiveness of the roller-crimper as a termination method to reduce tillage in organic systems.

Evaluation of Soil Amendments for Increasing Nutrients in Organic Farming

Prepared by the University of Saskatchewan, funded by the Agriculture Development Fund

Principle Investigator: Dr. JD Knight seeks to evaluate potential soil amendments for their ability to supply P and N to wheat and lentil crops grown under organic management.

 

Organic/Pesticide-free Higher Value Vegetable Crops: Sustainable Production, Maintain Quality and Extend Shelf-life

Prepared by Agriculture and Agri-Foods Canada, Funded by the Agriculture Development Fund

The organic fresh vegetable and fruit production is believed to be the most rapidly expanding sector in Organic Agriculture. This project is an initial attempt to (i) screen suitable vegetable crops for organic production under irrigation in Saskatchewan, and (ii) determine suitable storage and handling practices to extend the shelf life of organic vegetables.

 

Weed Management for Organic Farmers
Literature review by Brenda Frick

This literature review was requested by the Saskatchewan Organic Development Council (now SaskOrganics).  The document summarizes the weed control literature relevant to organic farmers and provides a baseline for future research efforts.  The document may be useful in determining research priorities, assessing the tools available for weed control in organic production and to organic farmers conducting their own research.

Enviroscan – Research & Extension Resources for Organic Farmers
Prepared for the Prairie Organic Grain Initiative (POGI)

The EnviroScan identifies and analyzes the research and extension resources available to guide organic producers, enabling them to improve their production practices. We examined the scientific and extension literature for the Canadian Prairies and adjacent USA states, over the last 35 years, with a focus on nutrient and weed management, grain quality and cultivars adapted to organic production. In our data collection, we also identified systems based research. A full listing of projects included in this resource can be downloaded here.
