Practical handling: what the label governs, why measuring by eye goes wrong, and how storage conditions change a product before it ever reaches a plant.

The decision not to feed is a real decision, and often the right one. Seven situations where adding fertiliser wastes money, does nothing, or actively harms...

Too much fertiliser produces symptoms that read as starvation — so the instinctive response is to add more. Recognising the pattern breaks a loop that kills...

Two separate analyses answering two different questions. Without them, every fertiliser decision is a guess — and in a region irrigating with possibly-saline water, the water...

Fertilisers are salts. On a soil already carrying a salt load, an application meant to help can push the plant further into the condition it is...

The same nutrient behaves differently depending on how it reaches the plant. Placement, dilution and irrigation all decide whether an application works or is wasted.

One gives a fast response and leaches fast. The other releases gradually and is harder to over-apply. On sandy soil under frequent irrigation the difference is...

Not a contest between good and bad. They differ in concentration, speed and what they do to the soil itself — and on low-organic-matter sandy soil...

On alkaline calcareous soil, the commonest nutrient problem is not absence but unavailability. Understanding pH explains why adding more of a nutrient sometimes changes nothing.

How to turn a declared percentage into a real quantity of nutrient — and why the oxide-to-element step matters. Method and worked examples, not a dose.

The three figures on every fertiliser bag are not a quality score. They are three different jobs, declared as percentages by weight — and two of...
