SCAN

SCAN IS A NEW PLATFORM THAT CALCULATES THE OPTIMAL DOSE OF NITROGEN FOR CORN WHEN APPLYING IT POST-EMERGENCE.

According to tests* conducted with more than 100 producers in Quebec over the past four years, SCAN enables potential gains of between $35 and $50 per hectare, versus doses evaluated by the producers and their consultants during corn fertilizer tests.

SCAN was developed by researcher Nicolas Tremblay and his team at the Agriculture and Agri-Food Canada Research Centre in Saint-Jean-sur-Richelieu. The calculation for the optimal dose of nitrogen takes into account the specific conditions of a management zone (soil texture, previous crop), meteorological conditions during the application period and economic parameters (cost of nitrogen, potential sales price of corn and yield potential).

The agronomic principles behind SCAN are explained in the technical information sheet “Aim for the optimal dose of nitrogen to reconcile profits and the environment. (https://www.craaq.qc.ca/Publications-du-CRAAQ/viser-la-dose-optimale-d_azote-pour-concilier-profits-et-environnement-pdf/p/PSOL0106-PDF#tab_tab3).

*The meta-analyses of historical databases of corn fertilization tests in North America, and the validation tests conducted with more than 100 producers in Quebec over four years demonstrated that the approach advocated by SCAN allows to determine the optimal economic dose post-emergence with the best possible accuracy for practical applications.
