SOIL TEST KIT #1: Investigates soil characteristics

•  (NPK) An economical, simple to use Soil Test Kit with step-by-step instructions supplied for testing for nitrogen, phosphorous and potassium concentration (NPK) in the soil.
•  Using the colour chart compares the colour of each sample to determine whether the concentration is low, medium or high.
•  Kit contents :
50x each of nitrate  |  Phosphorous and potassium test tabs  |  Flock test tabs  |  3x square plastic test tubes with stoppers  |  1x 30ml transparent plastic bottle for mixing  |  3ml plastic pipettors

(Wikipedia excerpt: ..."...A soil test [ST] is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted [ST] are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture. In geotechnical engineering, [ST] can be used to determine the current physical state of the soil, the seepage properties, the shear strength and the deformation properties of the soil. Other [ST] may be used in geochemical or ecological investigations.

In agriculture, a [ST] commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level. A [ST] can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals. The test is used to mimic the function of roots to assimilate minerals. The expected rate of growth is modeled by the Law of the Maximum.[1]...")
