A Note on Soil Type Compatibility

The Mehlich III extraction method was developed for acidic to neutral soils. In alkaline soils, it may overestimate plant-available nutrients —especially phosphorus and micronutrients. If you’re working in calcareous or high-pH soils, we recommend our Plant Natural® Soil Test for more accurate plant-available data.
