Description

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.

Objective(s)

  • Validate microbial indicators of soil productivity and the predictability, in terms of potato yield and quality, of the biological productivity score developed under project 901098 (IA113102)
  • Determine through economic analysis the farm-scale profitability of a management approach based on a combination of the validated biological productivity score and the optimum-nitrogen-dose model—This approach will have an impact on inputs and potato yields and quality

From 2017 to 2019

A comparative study of organic fertilizers with a high, effective nitrogen to total phosphorus ratio (Neff / Ptot) as a basis for developing productive and sustainable market gardening fertilization strategies

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
