PulseLogic™ · Open-field irrigation

Smart irrigation for
high-value crops.

Autonomous, sensor-driven water management for berries, fruit trees, vines, and specialty crops — short adaptive pulses tuned to real fields, not ideal conditions.

Why PulseLogic™ for open-field berries and orchard systems?

High-value crops growing in open fields are exposed to changing weather, variable soil types and rolling terrain. Research has shown that shorter, more frequent irrigation pulses can increase crop production and water productivity. PulseLogic puts that science to work with precise, zone-by-zone control. [1, 2]

Sensor-driven scheduling

Replaces calendar-based irrigation with decisions based on soil water potential, moisture and temperature. The system only irrigates when and where it's needed.

Zone-specific strategies

Different soil textures, slopes and varieties can be managed with their own targets and rules, so lighter ground doesn't get treated the same as heavy patches.

Weather-aware irrigation

Live weather and crop sensors allow PulseLogic to tighten or relax pulses in response to hot spells, cool cloudy days or unexpected rain, without you constantly reprogramming.

Water and fertilizer efficiency

By matching irrigation to plant demand and soil infiltration, you reduce runoff, deep percolation and wasted fertilizer, while keeping plants in their comfort zone.

New

Frost protection for cranberries

Built for cranberry growers: Ensemble monitors canopy temperature through cold nights and controls your sprinklers for frost protection, so the crop is covered before damage starts.

How pulse irrigation works in open fields

In open fields, soils can only absorb water at a certain rate. Long runs often lead to reduced aeration and runoff at the top of the slope and water pooling at the bottom. Pulse irrigation breaks irrigation into shorter applications through the day. This helps to:

Match soil infiltration

Short pulses let water soak in to maintain aeration and reduce root rot and runoff, especially on slopes or in heavier soils.

Stabilize root-zone moisture

Avoid big swings between very wet and very dry by topping up the profile with moderate pulses, guided by soil sensors at depth.

Use every millimeter

Make better use of each irrigation event and fertilizer unit by directing water into the active root zone instead of past it.

Putting the sensors to work: PulseLogic doesn't just run pulses on a schedule. It uses soil water potential, moisture and temperature at multiple depths to decide when to start, stop or skip irrigation events, taking out the guesswork.

Operating modes that fit your season

Autonomous production mode

You set the moisture or soil water potential targets and allowed time windows. PulseLogic handles the rest, choosing when and how long to run each zone to meet those targets. Easily override automation when needed (e.g., for harvest).

Heatwave protection

On high demand days, PulseLogic can adapt by tightening pulses, adding extra runs or prioritizing sensitive fields, using weather and canopy signals to avoid stress.

Establishment & shoulder seasons

Run gentler programs for young plantings or cooler periods. Easily scale up as canopy fills and demand increases, without rebuilding your schedule each time.

What PulseLogic™ measures and controls in the field

PulseLogic connects directly to your pumps, valves and in-field sensors. It gives you a live picture of how water moves through the soil profile, and uses that information to drive irrigation decisions.

Field sensing & crop insight

Soil water potential profile

A stack of sensors typically installed at three depths (e.g. 15, 30 and 45 cm) to track how water and stress move through the root zone. Fast changes near the surface, slower movement in the main roots, and deeper reserves are all visible in one profile.

Local weather station

Tracks on-farm wind, temperature and precipitation to inform irrigation decisions. Shows the actual climate your crop is experiencing, not just the nearest forecast.

EC & soil moisture sensor

Measures electrical conductivity (EC), soil moisture and temperature in the root zone. Links irrigation, salinity and plant response so you can see when you are pushing too hard or not feeding enough.

Node with solar power

Powers local sensors and sends data securely to the cloud. Typically based on solar power and cellular connectivity, enabling true remote operation.

Irrigation & fertigation control

Irrigation controller

Runs irrigation events, coordinates pumps and valves, and communicates with the cloud platform to apply your strategies zone by zone. Includes a touch screen to schedule and monitor irrigation events.

Discuss controller options

Solenoid valves

Open and close water to each zone, enabling independent pulse patterns and run times across the field from a single platform.

Dripline pressure sensor

Confirms the dripline is properly pressurized and flags issues like line breaks, blocked filters or solenoid faults early, so you don't lose a day of irrigation.

Cloud platform & grower app

View soil profiles, irrigation events and crop response across all your fields in one place. Adjust strategies, change targets and review past seasons from your office, tablet or phone, while PulseLogic runs the day-to-day in the field.

Peer-reviewed evidence

Research behind pulse irrigation

Commercial field studies in the Pacific Northwest compared pulse drip with continuous irrigation while applying the same total amount of water.

1 · Blueberry

Weather-based Scheduling and Pulse Drip Irrigation Increase Growth and Production of Northern Highbush Blueberry

In a two-year commercial blueberry study, pulse irrigation increased average berry weight by 0.10 g and diameter by 0.4 mm in the first year, while fruit bud set increased by 3.3 and 5.1 percentage points in years one and two, respectively—using the same amount of water as continuous irrigation. The authors found the approach especially promising for light-textured soils in hot, dry climates.

2 · Raspberry

Feasibility of Using Pulse Drip Irrigation for Increasing Growth, Yield, and Water Productivity of Red Raspberry

In a three-year commercial raspberry study, pulse irrigation produced about 1,100 lb more fruit per acre in years two and three—approximately 11% and 16% more, respectively—using about the same amount of water. The authors noted that more research is needed in heavier soils.

Start with a PulseLogic™ pilot field

We typically begin with a representative field to prove the approach in your soils and climate, then scale up once you're confident in the results. Share your current setup and goals, and we'll suggest a pilot design.
