Optimize product quality and ensure regulatory compliance with our Humic Acid and Fulvic Acid Testing. These essential analyses provide precise quantification of humic substances, critical for soil health, nutrient management, and agricultural efficiency.
Testing Covered:
✔ Total Humic Content – Confirms the percentage of humic substances in raw materials and finished products.
✔ % Humic Acid – Determines the concentration of humic acid in the sample for effective soil amendment application.
✔ % Fulvic Acid – Measures the bioactive fraction of humic substances that enhance nutrient uptake and plant growth.
✔ % Organic Matter – Evaluates the total organic composition, crucial for soil structure and microbial activity.
✔ % Moisture – Assesses water content to ensure product stability, consistency, and compliance with industry standards.
These tests support producers, distributors, and end-users in verifying product integrity, meeting industry standards, and optimizing formulations for agriculture, turf management, and soil remediation.Ensure your humic and fulvic acid products meet industry benchmarks—test with confidence today!

Ensure the quality and safety of your compost with the Seal of Testing Assurance (STA) Compost Test from the US Composting Council. This standardized program provides detailed analysis and certification to verify compost meets industry standards for environmental safety, nutrient content, and performance.
Our STA Compost Test evaluates key compost properties, including:
✅ Nutrient Profile – Measures nitrogen, phosphorus, potassium, and organic matter content.
✅ Maturity & Stability – Ensures the compost is fully processed and ready for use.
✅ Heavy Metals & Pathogens – Verifies compliance with safety standards for clean and safe compost.
✅ Soluble Salts & pH – Assesses suitability for plant growth and soil health.By participating in the US Composting Council's STA Program, compost producers and users can trust that their product meets rigorous scientific and environmental benchmarks. Whether you're a compost manufacturer, landscaper, or farmer, our testing helps you make informed decisions for sustainable soil management.
