FERTIGATION 🌱💧
WHEN IRRIGATION AND PLANT NUTRITION WORK TOGETHER
Can water and fertiliser be used more efficiently at the same time?
Fertigation is the application of water-soluble fertilisers through an irrigation system, most commonly drip irrigation. Nutrients are delivered directly to the root zone in small, controlled doses according to crop needs.
Fertigation can supply:
🌿 Nitrogen — urea, calcium nitrate or potassium nitrate.
🌱 Phosphorus — monoammonium phosphate or monopotassium phosphate.
🥔 Potassium — potassium nitrate or potassium sulphate.
🧪 Calcium and magnesium — calcium nitrate and magnesium sulphate.
🔬 Micronutrients — iron, boron, zinc and manganese in water-soluble forms.
Compared with conventional fertiliser application, a well-managed fertigation system provides more precise plant nutrition, reduces nutrient losses and, in some systems, may lower fertiliser use by approximately 15–25% without reducing yields.
However, successful implementation requires soil and water analysis, compatible fertilisers, correct equipment calibration and regular monitoring.
