Nutrigation™—the integration of plant nutrition with irrigation— has transformed modern agriculture by enabling precise, efficient, and sustainable nutrient management.
By delivering nutrients directly to the active root zone, Nutrigation™ supports optimal plant development, increases yields, enhances Nutrient Use Efficiency (NUE), and promotes sustainable farming practices.
Haifa offers comprehensive Nutrigation™ solutions, combining an extensive portfolio of specialty fertilizers with NutriNet™, an advanced digital tool for precision nutrient management.
What is fertigation
Fertigation is the precise application of fully soluble fertilizers through irrigation water. This method ensures that both water and nutrients reach the plant’s roots efficiently, improving nutrient uptake and reducing waste.
Fertigation is most effective with drip irrigation, where water and nutrients are delivered directly to the root zone. It is also effective in sprinkler irrigation (especially in orchards), pivot irrigation systems (center pivot or linear) and even where irrigation is delivered through flooded tunnels.
Specialty Fertigation: Nutrig
ation™ by Haifa
Unlike conventional fertigation—where fertilizers may contain non-essential or even harmful elements—Haifa’s Nutrigation™ delivers only pure, plant-available nutrients, ensuring maximum efficiency and soil health. This approach prevents nutrient imbalances and eliminates residues that can accumulate in the soil, ensuring healthier crops and long-term soil fertility.
A Powerful Tool for Precision Nutrition
Nutrigation™ enables maximum precision in plant nutrition:
- Precision Source – Using high-quality, fully water-soluble fertilizers tailored to the plant’s nutritional needs.
- Precise Rate – Adjusting fertilizer dosages based on soil analysis, crop type, and growth stage.
- Precise Timing – Synchronizing nutrient supply with plant demand to avoid deficiencies or excesses.
- Precision Place – Ensuring nutrients are delivered directly to the root zone for maximum efficiency.
Thus, Nutrigation™ fully aligns with the 4R Nutrient Stewardship principles—Right Source, Right Rate, Right Time, and Right Place.

The Benefits of Nutrigation™
- Higher Efficiency – Directs nutrients precisely where they are needed, improving absorption and minimizing waste.
- Uniform Plant Growth – Ensures equal nutrient distribution across the field, leading to homogeneous crop development.
- Superior Nutrient Availability – Nutrients are already dissolved, making them immediately accessible to plants.
- Maximum Flexibility – Easily adapted to various crops and growth stages, allowing for tailored fertilization programs.
- Increased Yields – Continuous nutrient supply eliminates deficiencies, promoting optimal growth and high yields.
- Positive Environmental Impact – Precision nutrition minimizes waste and pollution, reducing the environmental footprint of crop production and supporting sustainability.

Two Approaches to Nutrigation™
There are two main approaches to Nutrigation™:
- Quantitative Nutrigation™ delivers a predetermined amount of nutrients, independent of irrigation volume, making it ideal for medium to heavy soils.
- Proportional Nutrigation™ maintains a constant nutrient concentration in irrigation water, automatically adapting to the crop’s requirements at each growth stage—ideal for light soils, soilless cultivation, and hydroponics.
Haifa’s Specialty Products for Nutrigation™
Effective Nutrigation™ requires the precise injection of soluble fertilizers into irrigation water. This demands high-purity, fully water-soluble fertilizers that dissolve completely, ensuring clog-free irrigation systems and maximum nutrient uptake.
Haifa’s Nutrigation™ product range is designed to deliver the full spectrum of essential plant nutrients, including macronutrients (N, P, K), secondary nutrients (Ca, Mg, S) and micronutrients (Fe, Zn, Mn, B, Cu, Mo).
Key Features of Haifa’s Nutrigation™ Fertilizers:
- 100% pure plant nutrients – No fillers or unnecessary additives.
- Free from Harmful Elements – No sodium, chloride, or contaminants that could degrade soil health.
- Tailored for Every Growing Condition – Specialized grades for soilless and hydroponic systems.
