This LaMotte Combination soil test kits are the culmination of over 40 years of innovations in soil nutrient and pH testing. Modern advancements in chemistry have turned a great test kit into one of the most accurate and rapid testing solutions in use.
A series of chemical tests use standardized reagents to produce color reactions measured against laminated color charts. Colorimetric test methods are used for most test factors. Tests for calcium 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. 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.
The Humus Screening Test, performed on a soil sample-demineralized water suspension, employs five color standards for rapid measurement of humus content of the soil. Soil pH is determined colorimetrically, using a series of pH indicators and color charts covering the range of pH 3.8 to 9.6. This test kit also includes simplified procedures for screening nitrates, phosphorus and potassium in plant tissues.
All test kits are furnished in lightweight carrying cases which organize and protect the testing components in foam blocks. This makes this test kit great for laboratory testing as well as work in the field. Each kit includes complete instructions, a soil management handbook and a pad of soil analysis report forms which help to keep track of soil nutrient levels. The handbook features general information on the interpretation of test results for the determination of lime and other fertilizer requirements for optimal soil quality. The user manual has been attached to this page to answer any further questions.
