Soil Analysis and Fertilization Guide

Why soil analysis matters

A soil test puts numbers on what your land can and cannot supply. Without it, fertilization is guesswork — shaped by the local supplier’s recommendation or a neighbour’s habit. Both paths lead to the same outcome: either wasted spend on nutrients the soil already holds, or a yield ceiling caused by a deficiency nobody spotted.

In field work across Turkey, the most common situation I encounter is a grower who did get the test done, but left the interpretation to the seller. Reading a report correctly — understanding the interactions between pH, EC, organic matter and individual nutrients, and mapping them to the specific crop — is itself a specialist task.

What a good fertilization programme covers

A programme brings together the soil test, the crop’s seasonal demand curve, the irrigation system and the available fertilizer sources. Nitrogen leads during vegetative growth; phosphorus and potassium take over at flowering and fruiting; certain micronutrients are only available in a narrow pH band. Getting the timing wrong matters as much as getting the quantity wrong.

For operations with fertigation, the programme is integrated with EC and pH targets in the drip line. Drain water monitoring is the feedback loop that confirms the programme is working.

What this silo covers

• Reading the soil test report: Interpreting pH, EC, organic matter and nutrient values in plain terms
• Building a fertilization programme: Step-by-step plan, source selection and seasonal scheduling
• Fertigation: Feeding through the drip line; EC-pH management and drain monitoring
• Leaf tissue analysis: Seeing what soil tests cannot — uptake barriers and hidden deficiencies
