Alberta pulse crop growers running the OA-Ag Foliar Add-On Program saw 15–20% yield increases and enhanced nitrogen fixation. Here's the data behind the FCB Castor Bean Foliar product.
Pulse crops — lentils, peas, chickpeas — rely on rhizobial nitrogen fixation as a core part of their fertility equation. But root zone salt stress, poor soil biology, and inadequate carbon levels all suppress that fixation. OA-Ag's Foliar Add-On Program addresses this with FCB Castor Bean Foliar, a carbon-rich foliar product with a salt index below 18 that supports plant health without disrupting the root biology that pulse crops depend on.
The Foliar Add-On Program is OA-Ag's lowest-barrier entry point — no changes to in-ground fertility, no fertigation equipment required. It uses standard spray application and is compatible with tank mixes. For pulse crops where margins are tight and nitrogen input costs are significant, a 15–20% yield lift with a program that costs less than most synthetic foliar programs represents a compelling return.
"The foliar program paid for itself in the first season. We're seeing the soil biology respond in ways we didn't expect." — Alberta Pulse Farmer, Lentil & Pea Operations
