Meet Landscape Architect Specs with Confidence—Certified, Comprehensive, and Accurate

Designed for Compliance. Trusted for Performance.

When you're working on a professional landscape project, the soil must meet specific performance standards— no guesswork, no shortcuts. Our Landscapers' Comprehensive Soil Test is engineered to meet the exacting requirements of landscape architects, engineers, and municipal planners. It includes all the most requested analyses for verifying soil quality, compliance with project specs, and long-term landscape success.

From nutrient content to texture, from Solvita maturity to particle size—this is the go-to test for specifying or approving engineered soils, compost blends, or planting media.

Why This Test Package Stands Out

• ✔️ Meets industry standards for landscape installation and soil spec verification
• ✔️ Comprehensive analysis —physical, chemical, and biological components in one report
• ✔️ Accepted by public agencies and third-party inspectors
• ✔️ Ideal for submittals, sourcing decisions, and project compliance

What’s Included in Your Analysis

Total Nutrients (Bulk Analysis)

Evaluate the full nutrient holding capacity of the material:

• % Nitrogen (N)
• % Phosphorus (P), Total Phosphate (% P₂O₅), Phosphate (ppm PO₄)
• % Potassium (K), Total Potash (as K₂O)
• Sodium (Na), Calcium (Ca), Magnesium (Mg)
• Micronutrients: Zinc (Zn), Iron (Fe), Manganese (Mn), Copper (Cu), Boron (B)
• Sulfur (S)

Available Nutrients (Mehlich III Extractable)

• Sodium (Na), Calcium (Ca), Magnesium (Mg)
• Iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu)
• Sulfur (S)

Basic Soil Properties

Verify suitability for planting and long-term plant health:

• Electrical Conductivity (EC) – Salinity measurement
• pH – Nutrient availability and root compatibility
• Total Organic Matter (LOI)
• Total Carbon (C)
• Carbon-to-Nitrogen Ratio (C:N)
• Solvita® Maturity Index – Biological stability and decomposition stage
• Texture (Bouyoucos method)
• Moisture content (%)
• Particle Size Distribution (3/8" & 5/8" sieves)
• Inert or Deleterious Materials – % Plastic, Glass, Metal

Who This Test Is For:

• Landscape Architects creating or validating project specs
• Compost & soil suppliers providing material to spec-driven projects
• Municipal planners and DOT contractors needing compliant media
• Commercial landscapers verifying site prep materials

Sample Requirements & Turnaround

• Minimum Sample Size: 1 gallon
• Turnaround Time: 5–7 business days from lab receipt
• Report Format: Clear, project-ready report with full lab data and interpretations
