What does the soil test in the Natural Plant Selector Kit test analyze?
The analysis, from an accredited university lab, gives results for soil particle size (texture) and the degree of acidity or alkalinity (pH). Additional data specific to your objectives may include either macro nutrients N (Nitrogen), P (Phosphorus) and K (Potassium) or balance of sodium, magnesium and calcium ions (SAR) and electrical conductivity (EC).
