Fast, Affordable Nutrient Snapshot for Acidic or Neutral Soils

A No-Frills Soil Nutrient Analysis—Done Right

Looking for a quick, cost-effective look at your soil’s basic fertility? The Mehlich III Basic Soil Test delivers a streamlined nutrient panel using the same extraction method used by university and extension labs across the country.

This is an ideal test for routine monitoring, home gardens, budget-conscious projects, or as a baseline check before diving into more comprehensive testing. While it has some limitations on high-pH (alkaline) soils, it’s a reliable choice for many standard field and garden soils.

What’s Included in Your Analysis

Tested using the Mehlich III strong-acid extraction:

• Calcium (Ca) – Essential for root strength, nutrient uptake, and soil structure
• Magnesium (Mg) – Supports chlorophyll production and photosynthesis
• Sodium (Na) – High levels can impact soil structure and crop health
• Potassium (K) – Critical for fruit quality, disease resistance, and drought tolerance
• Phosphorus (P) – Key for root development and energy transfer
• CEC- Cation Exchange Capacity
• Saturated Paste Values(calculated)

Sample Requirements & Turnaround

• Minimum Sample Size: 3–4 cups of soil
• Turnaround Time: 3–5 business days from lab receipt

Important Notes

• This test uses the Mehlich III extraction method, ideal for acidic to neutral soils.
  In alkaline soils, this method may overestimate nutrient availability, especially phosphorus and micronutrients.
• No interpretations or fertilizer recommendations are included with this test.
  It’s best suited for agronomists, consultants, or experienced growers who can interpret results independently.

Perfect For:

• Budget-conscious growers and hobbyists
• Baseline nutrient checks before planting
• DIY soil enthusiasts using third-party tools for interpretation
• Consultants or resellers needing quick, raw data for acidic soils
