Landscapers' Comprehensive Soil Test
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
