Description
Plots were set up at the Organic Agriculture Innovation Platform in St-Bruno-de-Montarville, Québec. They included nine treatments replicated four times in a split-plot design with green manure (none, grain, and legumes) in the main plots and fertilization methods in the subplots (no fertilizer, poultry manure pellets, and composted beef manure).
Objective(s)
- Quantify the effect of different combinations of green manure and organic fertilizers on:
- Microbial populations and their activity in the soil
- Marketable carrot yields
- Nitrogen mineralization and soil and carrot nitrate, macronutrient, and micronutrient content
- E. coli persistence in the soil and on the crop
- The economic yield of these production systems
From 2014 to 2017

Potato fertigation using a drip irrigation system
The aim of this project was to leverage the efficiency of drip irrigation and splitting nitrogen inputs into multiple applications to reduce total nitrogen inputs per unit produced and provide better economic and environmental alternatives to conventional irrigation.

Evaluating the effect of seeds coated with commercial, mycorrhizal fungi inoculum on the yields of nantes carrots grown in mineral soil early in the organic transition process
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
