IRDA identified microbial indicators based on data collected at 64 sampling points in 16 production zones in Québec from 2013 to 2015 as part of the project IRDA-901098 (IA116102). The microbial indicators are used to calculate a biological productivity score for soils in potato fields.
The current project is designed to check the predictability of the biological productivity score using these microbial indicators for rotation crop years and potato crop years.
Partners in the industry will help evaluate 240 new sampling points in 60 production zones. An economic analysis will be conducted to assess the farm-scale profitability of a management approach based on a combination of the validated biological score and the optimum-nitrogen-dose model.
From 2017 to 2019
IRDA offers a wide range of metagenomic analyses for the identification and characterization of soil populations.

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.
