SOIL TEST KIT #2: Investigates soil characteristics

Students investigate the nature  of soils, observing and characterizing based on physical examination of the chemical composition and the microbial community studied. Intended for a small group demonstration, or repeated for an individual investigator. Requires two 45-minute class periods.

(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]...")
