Estimate your soil CEC rating and understand its nutrient-holding capacity to make better fertilizer decisions.
What is CEC? Cation Exchange Capacity (meq/100g) measures how well your soil holds positively charged nutrients like Ca, Mg, K, and NH4. Higher CEC means better nutrient retention and less leaching.
Source: CEC estimation based on USDA NRCS Soil Survey methods and Brady & Weil “The Nature and Properties of Soils.” Results are estimates — lab-measured CEC (ammonium acetate method) is more accurate.
