Abstract
An engineered soilless plant cultivation medium for potting applications includes specific balanced amounts of nutrient additives. Major nutrient cations (Ca, Mg, K, Na, H) are balanced according to optimal base saturation percentage ranges. Nutrient levels, namely, the amount of major nutrient cations, major nutrient anions and minor nutrients satisfy desired ranges for both standard Mehlich III soil extraction tests and saturated paste tests.
