The (agricultural) soil test kits offer simplified methods for determination of available nutrients found in agricultural soils. A series of rapid, accurate chemical tests use standardized reagents to produce color reactions measured against laminated color charts. Colorimetric test methods are used for most test factors. Some tests are based on turbidity measurements. A single extraction procedure (We recommend our water samplers for obtaining soil water samples from root zones) provides the liquid soil extract for all the nutrient tests. Soil pH is determined colorimetrically, covering the range of pH 3.8 to 9.6. Complete reagent refill packages are available for each outfit. All kits outfits are furnished in lightweight carrying cases with components securely mounted.
