Total Nutrient Digest (TND) - Complete Soil Nutrient Analysis
Know Your Soil's True Nutrient Potential The Total Nutrient Digest (TND) reveals your soil's complete nutrient net worth—not just what's available today, but the total nutrient reserves your soil holds. While standard extract tests show you what's immediately accessible to plants, TND gives you the full picture of your soil's long-term fertility capacity. Complete 13-Element Analysis: Macronutrients: Carbon, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur Micronutrients: Zinc, Iron, Manganese, Copper, Boron, Molybdenum Why TND Matters Understanding your soil's total nutrient reserves helps you make smarter fertilization decisions. Instead of chasing short-term availability numbers, you'll know the true mineral wealth locked in your soil—and whether you need to build reserves or simply unlock what's already there through biological activity and proper pH management. The Difference Between Available vs. Total Most soil tests measure what's plant-available right now. TN
