Is Your Irrigation Water Stealing Nutrients from Your Crops?

by ouidad laadim / 2026 November 11

A good fertigation program is not only about choosing the right fertilizer. Irrigation water quality can determine how efficiently those nutrients reach the crop.

High bicarbonate (HCO₃⁻) levels increase water alkalinity and make pH more difficult to control. Under unfavorable conditions, this can encourage nutrient precipitation and mineral deposits within the irrigation system.

When Bicarbonates Become a Problem

Bicarbonate-rich irrigation water can contribute to:

  • reduced nutrient availability;
  • precipitation of nutrients such as calcium, magnesium and phosphorus;
  • sediment formation in nutrient solutions;
  • clogging of filters and drip emitters;
  • less efficient and uniform fertigation.

This means that even when nutrients are applied correctly, water chemistry may limit the efficiency of the nutrition program.

Nutrion pH 2: Turn Water Management into Crop Nutrition

Nutrion pH 2 combines plant nutrition with water conditioning.

Its acidifying properties help neutralize bicarbonates and manage the pH of fertigation solutions, while supplying essential nutrients:

13.3% N | 1% P₂O₅ | 45.5% K₂O | pH 2.0 in a 10% solution
Nutrion K pH 2 specifications: 13.3% total nitrogen, 13.3% nitrate nitrogen, 45.5% K2O, 1% P2O5, pH 2.0, bulk density 1.1 g/cm³

The result is a single solution designed to support:

✓ Bicarbonate control
✓ Better pH management
✓ Improved nutrient solubility
✓ Reduced risk of precipitation and deposits
✓ Efficient nitrogen and potassium nutrition

Irrigation water with high bicarbonates becomes a stable solution after adding Nutrion K pH 2

Better Water. Better Nutrition. Better Fertigation.

Understanding irrigation water is the first step. A water analysis including pH, EC and bicarbonates can help growers identify the problem and adapt their fertigation strategy accordingly.

With Nutrion pH 2, FERTIMED brings water conditioning and crop nutrition together in one practical approach.

Because better nutrition starts with better water.
