This advanced reagent system and unique extraction procedure based on the Mehlich I extraction provides fast, simple, and accurate soil testing
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, which uses a unique reading device designed to read directly in pounds per acre. A single extraction procedure, using Morgan universal extraction solution, provides the liquid soil extract for all of the nutrient tests with the exception of chloride, which is extracted with demineralized water. The humus screening test, performed on a soil sample-demineralized water suspension, uses five color standards for rapid measurement of humus content. Soil pH is determined colorimetrically using a series of pH indicators and color charts. Also included are simplified procedures for screening nitrates, phosphorus, and potassium in plant tissues.
Outfit contains 50 test of each type except pH which has 100.
A series of rapid, accurate chemical tests use standardized reagents to produce color reactions measured against laminated color charts.
Ordering information: Kit is furnished with a lightweight carrying case with all components securely mounted in removable foam trays. Each kit includes complete instructions, a pad of soil analysis report forms, and a soil management handbook containing information on interpreting test results for determining lime and fertilizer requirements.
