Farm nitrogen (N) fertilization practices are receiving major attention across Canada, stimulated by the combination of very high prices for N materials and concerns over fertilizer-linked nitrous oxide (N2O) emissions – N2O being a powerful greenhouse gas.
The 4R approach promoted by the North American fertilizer industry (reference here ) – Right Material, Right Timing, Right Placement and Right Rate – has been featured in many discussions, and rightly so. It’s a good approach.
Of the four Rs, we have good guidance from research on three. The use of urease and nitrification inhibitors and polymer-coated urea means better N-use efficiency in many cases and less N2O. Soil incorporation is usually better than non-incorporation. And split applications, with some N applied near planting time followed by more 4 to 10 weeks later for corn is usually better than all applied at planting.
