Research Projects

Each year, IRDA's R&D Team conducts more than one hundred research projects in sustainable agriculture. What's more, IRDA is working with Quebec's key agricultural stakeholders to find concrete solutions.

Results for Fruit production

Banded controlled-release and conventional fertilizer in horticultural production under plastic mulch

The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.
