LAMOTTE 5173-N

The Modifed Morgan Universal Extraction Solution is the standard soil extracting solution for many professional soil labs and universities for finding the nutrients that will dissolve and be available for your plants. The extraction solution was developed at the University of Connecticut in the 1930's for use on acidic New England soils. Most New England State Universities including University of Maine and Cornell University still use the (modified) Morgan extract. The Morgan extract is a "universal" extractant, meaning all major nutrients (including phosphorus) and many micronutrients can all be measured in the one extract. A single extraction procedure, using Morgan Universal Extraction Solution, provides the liquid soil extract for all the nutrient tests with the exception of chloride, which is extracted with demineralized water. For Lamotte Chemical test kits, Colorimetric test methods are used for most test factors. Tests for calcium, sulfate and chlorides are based on turbidity measurements. Potassium analysis also employs a turbidity measurement, using a unique reading device designed in LaMotte laboratories to read directly in pounds per acre.
