What Is Driving the Price

Turkish mine production

Eti Maden (Turkey) controls majority of global boron mining; supply is relatively stable.

Alfalfa and canola demand

Boron-responsive crops (alfalfa, canola, sunflower) drive regional demand spikes.

Soil pH and texture

Sandy, acidic soils leach boron rapidly, requiring more frequent application.

Foliar vs. soil application

Foliar boron costs more per unit but requires less product and corrects faster.
