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

Assessing the potential of using granulated potato residues to produce animal feed, fertilizers, and energy

Managing potato residues is therefore a big challenge, which will only increase with the enforcement of the Québec Residual Materials Waste Management Policy.

Biological characterization of soils to increase potato productivity and soil sustainability

To increase the productivity of potato production systems and preserve soil quality, we need to enhance our knowledge of interactions among biological, physical, chemical, and agronomic characteristics of cultivated soils in various environments.

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.
