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
