Irrigation and Fertigation

Fruit quality improves when water and nutrients reach the tree at the right time and in the right amount. We design your drip irrigation and fertigation system and stay with you through installation and day-to-day operation.

Why it matters

In modern orchards, especially high-density plantings on dwarfing and semi-dwarfing rootstocks, the root zone is small. Trees react quickly to even short periods of water stress. Too much water, on the other hand, encourages root disease, leaches nutrients and lowers fruit quality. In cherries, the weeks before harvest drive fruit size. The weeks after harvest are when next year's flower buds form. Irrigation has to continue with care after the fruit is picked.

Drip irrigation and fertigation deliver water and nutrients to the root zone in a controlled way. A well-built, well-run system uses less water, makes fertilizer work harder and supports sustainable orchard management.

What we assess

  • Water source and capacity: Well, reservoir or canal water; flow rate, storage and pressure.
  • Water quality: EC, SAR, pH, bicarbonate, boron, chloride, iron and suspended solids. These shape both the filtration choice and the nutrient program.
  • Soil: Texture and water-holding capacity, which set dripper spacing and flow rate.
  • Orchard layout: Row length, slope, irrigation zones and single or double lateral lines.
  • Crop water demand: Local reference evapotranspiration (ET), crop coefficients and seasonal needs by tree age.

Our process

  1. Survey and analysis: We study the water source, water quality and soil.
  2. System design: We specify pump, filtration, mainlines, zones, dripper type and spacing. We add fertilizer tanks, injection equipment and, where needed, acid dosing.
  3. Installation support: We work alongside the installer and check on site that the build follows the design.
  4. Commissioning: We run pressure and flow tests and measure how evenly the drippers deliver water.
  5. Irrigation schedule: We build a weekly plan using ET data and soil moisture sensors.
  6. Fertigation program: We link a seasonal nutrient plan, based on soil and leaf analysis, to the irrigation schedule.
  7. Monitoring and maintenance: We set up routines for filter cleaning, line flushing and preventing dripper clogging.

Sensors and data-driven irrigation

We recommend irrigating by measurement, not by calendar. Soil moisture sensors show when water in the root zone is running low and how deep each irrigation reaches. Combined with ET calculations, they make it much easier to avoid both under- and over-watering. We also train your team to read the data and act on it.

Getting fertigation right

Fertilizer compatibility matters. Calcium fertilizers, for example, should not be mixed with sulfate or phosphate fertilizers in the same tank. They form precipitates that block drippers. Regular checks of solution EC and pH protect both the trees and the system.

We also recommend injecting fertilizer in the middle of the irrigation cycle. The lines fill with water first and are flushed with clean water at the end. Nutrients spread evenly through the root zone and no fertilizer residue builds up in the lines. Simple rules like this keep a system running well for years.

Who is it for?

  • Investors installing drip irrigation and fertigation in a new orchard
  • Growers who are not getting results from their current system
  • Corporate farms that want to measure and manage water and fertilizer use

Frequently Asked Questions

There is no fixed calendar. The interval depends on soil water-holding capacity, tree age, rootstock and weather. That is why we build schedules from ET data and soil moisture sensors. Keep irrigating after harvest, because next year's flower buds form during that period.

Fertigation delivers nutrients with the water, directly to the active root zone and in small doses. Trees get what they need when they need it, and losses from leaching drop. A good program should always rest on soil and leaf analysis.

Yes. We measure pressure, flow and dripper uniformity and review filtration and zoning. We then report the problems and improvements in order of priority.

High EC or SAR can cause salinity and damage soil structure. High bicarbonate, iron and suspended solids clog drippers. Water analysis guides the choice of filters, acid treatment and fertilizers.
