Full Nutrient and Salinity Profile for Regulatory & Conservation Projects

Designed for Compliance, Land Applications, and Conservation Programs

The Mehlich III Full – TCEQ / EQIP soil analysis package is tailored for use in state and federally regulated land application projects, including those under TCEQ (Texas Commission on Environmental Quality) and EQIP (Environmental Quality Incentives Program) guidelines. It provides a thorough profile of macro nutrients, soluble salts, and total vs. extractable minerals—exactly what contractors, consultants, and land managers need for permitting, reporting, or nutrient management planning.

Whether you're working on biosolid application projects, CAFO site evaluations, conservation land improvement, or NRCS cost-share programs, this package meets technical requirements for many regulatory and grant-funded applications.

What’s Included in Your Analysis

Tested using the Mehlich III strong-acid extraction method, plus key salinity and total nutrient markers:

Soil Chemistry & Salinity

• pH – Measures soil acidity or alkalinity
• Electrical Conductivity (EC) – Indicates soluble salt levels
• Sodium Adsorption Ratio (SAR) – Assesses sodium hazard to infiltration and permeability
• % Total Organic Matter – Reflects carbon content and nutrient retention potential

Nutrients (Total & Soluble)

• Nitrate-Nitrogen (N-NO₃) – Bioavailable form of nitrogen
• Total Phosphorus (P) – Required for nutrient loading calculations
• Total Potassium (K)
• Total Calcium (Ca)
• Total Magnesium (Mg)
• Total Sodium (Na)

Soluble (Plant-Available) Nutrients

• Soluble Calcium (Ca)
• Soluble Magnesium (Mg)
• Soluble Sodium (Na)
• Sulfur (as SO₄-S) – Important for salinity interpretation and crop tolerance

Who Uses This Test?

• Environmental consultants preparing TCEQ permit applications
• EQIP or NRCS participants managing nutrient plans and conservation grants
• Compost or biosolid land application contractors
• Erosion control & reclamation professionals
• Soil scientists and agronomists working with CAFO or municipal land use projects
• Engineering firms evaluating soil suitability for site development or restoration

Sample Requirements & Turnaround

• Sample Size: 3–4 cups of soil
• Turnaround Time: 3–5 business days from lab receipt
• Report Format: Lab data only – no fertilizer recommendations or interpretations included

Important Notes

• Uses Mehlich III extraction, which is ideal for acidic to neutral soils
• In alkaline soils, nutrient levels may appear inflated due to over-extraction
• Designed for projects requiring data compliance, not crop-specific management advice
