Soil, Fertilizer & WateringDoes an extractable nutrient result measure every pound of that element in mango soil?
Routine soil methods extract a defined fraction associated with nutrient availability, rather than measuring the entire mineral inventory. The interpretation depends on calibration of that method for relevant soils and crops. Do not treat a reported concentration as a complete account of what the tree can obtain over its lifetime. Ask how the result relates to an actual fertilizer decision.
