Have high pH soils?

AEA Consultant Shelley Katz explains how high pH soils limit nutrient uptake, and why she uses foliars to guarantee her plants get the nutrients they need.

Shelley's recommended reading in Marschner's Mineral Nutrition:
➡️ low availability of micronutrients in high pH soil (p. 83)
➡️ soil biology and root exudate influence on nutrient availability (p. 368)
