Soil, Fertilizer & WateringHow should soil sampling depth be chosen for a mango?
Use the laboratory's crop-specific protocol and record the depth so later samples can be compared fairly. A surface fertility sample and a deeper investigation of salinity or restricted drainage serve different purposes. Keep depths separate when investigating a soil profile rather than mixing everything into one bag. Consistent sampling is more useful than collecting an arbitrary handful from whichever spot is easiest to reach.
