Two lots the same size, planted the same year, can yield quite differently for a reason that has nothing to do with fertiliser dose or harvest timing — the soil under them holds and releases nutrients differently, and that shapes what the palm can actually use.
This is exactly why MPOB’s F-series compound fertilisers exist as separate products by soil type rather than one universal blend — see our full F-series-by-soil guide for the specific product each type calls for, and the dosage table for how much of it, once age is factored in too.
Many smallholders inherit a rough sense of their soil from how the land behaves — waterlogs easily, drains too fast, has visible peat depth — which is usually enough to pick the right product family. For a lot where it’s genuinely unclear, or where yield is underperforming without an obvious cause, a proper soil test through your nearest MPOB or Department of Agriculture office settles it more precisely than guessing.
