The most limiting factor for tree growth on this soil appears to be soil pH, as indicated by the wide variation in tree height (from 1.5 to 6 meters) despite all other factors (water, nitrogen, phosphorus) being kept constant. Soil pH outside of the optimal range can limit nutrient availability and uptake, which can in turn limit plant growth.
