Automated Drip Irrigation Systems for Agriculture Compared

An automated drip irrigation system for agriculture is a drip network with electric or battery-powered valves and a controller that opens and closes them on a schedule, a sensor reading or a weather signal, so nobody has to walk the field to switch zones. Drip, trickle and other low-flow systems watered 6.43 million acres of open fields on US farms in 2023, about 12% of irrigated open-field acres, according to the USDA irrigation survey. This guide compares five farm-scale systems, shows what trials found on water and labour, and gives a payback calculator you can fill in with your own numbers.

It is written for farm owners and managers who already run drip, or plan to, and want to know which kind of control is worth paying for.

What an automated drip irrigation system for agriculture includes

Automation replaces the person who opens and closes valves. Water still moves through the same parts as in a manual drip irrigation system: a pump or pressurised supply, a filter, an optional fertiliser injector, a mainline, and drip lines with emitters in each zone. Automation adds three things:

• Valves that take a signal. Each zone gets a solenoid valve, which opens and shuts on an electrical pulse. Many existing hydraulic valves can be fitted with a solenoid instead of being replaced.
• A controller. It decides when each valve opens and for how long. It can sit in a shed, on a pole in the field, or run as a small battery unit at each valve.
• Inputs. Soil moisture probes, a weather station, flow meters or pressure sensors tell the controller what the field needs and warn of leaks or blocked filters.

A communication layer links these parts. It can be wires, radio units in the field, a mesh of wireless nodes, or a cellular or Wi-Fi link to a cloud platform that you open on a phone.

Filtration matters as much as the controller. A clogged emitter waters nothing, whatever the schedule says. University of Kentucky Extension notes that sand filters may be needed for surface water, while cheaper disc filters can work on small farms.

Four levels of control, from timers to cloud

Irrigation automation comes in four broad levels. Each one adds cost and one more thing to maintain, so pick the lowest level that solves your real problem.

1. Timer-based. The controller runs a fixed schedule. It is cheap and simple, but it waters whether the soil needs it or not.
2. Sensor-based. A soil moisture reading starts or skips a cycle, so water goes on only when the root zone dries past a set point.
3. Weather or ET-based. The controller adjusts run times from rainfall and evapotranspiration (ET) data, either from an on-farm station or a weather service.
4. Cloud-managed. Controllers connect to a phone app or web platform, so a grower can change schedules, see flow alarms and run fertigation across many blocks from one screen.

Most US irrigators still decide by eye and hand. In the 2023 survey, 164,779 of the 212,714 farms that reported a method watched the condition of the crop, and 85,093 judged the feel of the soil. Only 27,831 farms used a soil moisture sensing device, about 13% (USDA NASS, 2023). Farms could report more than one method, so the counts overlap.

That gap is the case for automation. A controller cannot judge a crop by eye, but it can act on a sensor reading at 3 a.m., and it can repeat short cycles that are hard to run by hand.

How we chose the five systems

We looked for systems sold for farm drip irrigation, not lawns, golf courses or sports fields. Each one had to be listed under the same name on the maker’s own website, control valves in the field (or, in one case, pair a controller with scheduling software), and support more than a handful of zones.

We did not test the hardware. The descriptions below come from each maker’s pages and, where one exists, an independent report or university project. None of the makers show prices on their product pages, so ask dealers for quotes. The order is not a ranking: each system fits a different farm.

Two platforms in the older version of this article were left out. Rain Bird’s IQ4 central control is aimed at commercial landscape sites such as parks, schools and housing associations, and Jain Irrigation’s international business was merged into Rivulis (announced June 2022, completed April 2023), so the Rivulis entry covers that group.

Five automated drip irrigation systems for agriculture compared

1. Netafim GrowSphere controllers

GrowSphere is Netafim’s operating system for irrigation and fertigation. It links controllers, sensors, a cloud service and a phone app, with modules for monitoring, remote valve control, alerts, reports and a Crop Advisor that suggests irrigation plans by crop stage. Netafim lists two controllers: GrowSphere MAX, for medium to large farms, handles up to 256 valves, more than 100 sensors and advanced fertigation; GrowSphere FLEX, for small to medium farms, handles 16 valves, one mainline and simple fertigation.

Best for: medium and large drip or micro-sprinkler farms with fertigation, such as orchards, field crops and protected crops, that want controller, sensors and software from one supplier.

• Pros: one platform for planning, control and reports; scales from 16 to 256 valves; fertigation built in; crop-stage plan suggestions.
• Cons: no public price list; Netafim says return on investment depends on crop, farm size and local conditions; you depend on a local dealer for setup and service.

2. Rivulis controllers with Manna scheduling

Rivulis, whose brands include Eurodrip and T-Tape, describes two steps to automation. The first is adding a controller and solenoids to a manual system; existing hydraulic valves can often be fitted with a solenoid. The controller can run only the field valves, or the whole head: pump, main valve, filter backflush and fertigation. Signals travel by wire, by hydraulic tube, or by wireless remote terminal units. The second step is decision support. Manna Irrigation Intelligence combines satellite images, local weather data and irrigation protocols to recommend how much to irrigate, without sensors in the field.

Best for: growers who already run Rivulis, Eurodrip or T-Tape drip and want to automate in stages, starting with valves and adding scheduling advice later.

• Pros: retrofit route keeps existing valves; options from field-valve control to full head control; sensor-free scheduling advice.
• Cons: the Rivulis automation guide does not name a controller model, so ask the dealer exactly which hardware you will get; Manna gives recommendations, it does not open valves by itself.

3. Toro Tempus AG

Toro announced its Tempus automation system for farm irrigation in the US in February 2022. The Tempus AG-CT field controller runs on a 9-volt battery, talks over Bluetooth and LoRa radio, and operates up to six latching solenoid valves. It can schedule by cycle, by volume or by rainfall. The AG-MV unit controls the main valve. A base station covers a radio area of up to about 5,200 feet (1.6 km) and sends data to the cloud over cellular or Wi-Fi; base stations can be solar powered or wired, and more of them extend the range.

Best for: fields with no power at the valves, where a battery unit at each valve is easier than trenching cable.

• Pros: no wiring to valves; quick install; devices support drop-a-pin geolocation; volume and rainfall-based programs.
• Cons: needs base station coverage over every block; batteries need checking; up to six valves per field unit; ask a Toro dealer for prices.

4. WiseConn DropControl

DropControl is WiseConn’s platform for monitoring and controlling irrigation and fertigation over a wireless network. WiseConn shows it on orchard crops such as almond, citrus, cherry, olive, pistachio, walnut and blueberry. The FAO Agritech Observatory listing describes solar-powered field nodes in a wireless mesh, sensors for soil moisture, flow, pressure and weather, and control of pumps, valves and fertigation equipment. The same listing says hardware is sold upfront and the software, analytics and remote control come as a subscription.

Best for: medium and large farms with many blocks, such as orchards, where solar-powered nodes can stay in place for years.

• Pros: monitoring and control on one network; solar nodes; fertigation control; open to other software through an API.
• Cons: yearly subscription on top of hardware; no public prices; WiseConn’s own crop pages show orchard and berry crops.

5. Talgil Dream 2

Talgil, founded in 1987, lists the Dream 2 as a professional irrigation controller, with filter backflush controllers and remote terminal units (RTUs) that link to valves by radio or a two-wire cable. A 2025 professional-degree thesis at the National Agrarian University La Molina in Peru describes a Dream 2 install on a 146.3-hectare farm of blueberries grown in bags in Ica, with RTUs, sensors, solenoids, fertigation tables and radio links. The thesis gives an investment of USD 915.03 per hectare (about USD 370 per acre) and an 88% cut in the manual irrigation workload.

Best for: large export fruit and vegetable farms in Latin America, Europe and Australia that need detailed fertigation and filter control and have a local Talgil dealer.

• Pros: mature controller line; radio and two-wire RTU options; fertigation and backflush control; one documented farm-scale install with costs.
• Cons: the Peru figures come from one student project, not a controlled trial; programming is detailed and needs training; no public prices.

Side-by-side comparison

What field trials say about water and labour

There is no single typical saving. It depends on the crop, the soil, the climate and the practice you compare against. University of Florida research gives a clear picture of the range. In the trials summarised in the UF/IFAS EDIS fact sheet on automatic irrigation based on soil moisture, revised in August 2024, which summarises trials from 2003 to 2005:

Chart

Water saved by soil moisture control in Florida trials

Percent less irrigation water than the comparison practice, selected trials

• Switching tensiometers on drip-irrigated tomato on a coarse soil used 70% less water than farmer practice, with similar yields.
• A dielectric-probe controller cut irrigation water by 70% on drip-irrigated tomato in south Florida.
• Sensor-controlled bell pepper used 50% less water than a once-a-day manual schedule with similar yields, but the highest yields came from the farmer treatment watered once or twice a day.
• On-demand subsurface drip in a sweet corn and peanut rotation used 11% less water than sprinklers, with similar yields.

The same fact sheet warns that sensor types do not all perform alike, and that the number and position of sensors matter because soil varies across a field.

Labour savings matter too. In a UF/IFAS assessment of nine watermelon growers on 1,883 acres in Florida’s Suwannee Valley, wireless valve automation saved an estimated 164 million gallons of water in 2024. Daily irrigation run time fell by 1.4 hours on average, and growers spent 1.7 fewer hours in the field each day. Two-thirds of the surveyed farmers said they would not have bought the equipment without cost-share help.

Where farms use drip irrigation in the US

Drip area is growing while total irrigated area shrinks. US farms watered 53.1 million acres of open fields in 2023, down from 55.9 million in 2018, but drip, trickle and low-flow acres rose from 5.86 million to 6.43 million (USDA NASS, 2023). Surface drip made up most of the gain.

Million acres irrigated in fields in the open, 2018 and 2023

California dominates. Its 4.36 million drip acres in 2023 were about two-thirds of the US total, and Texas, Florida and Washington followed far behind. If you farm outside those states, your nearest drip dealer and the nearest extension specialist who knows automation may be some distance away, so ask about service before you buy.

What automation costs, with examples

Costs vary so much by farm that a single per-acre figure would mislead you. These dated examples show the scale:

The Kentucky figure is for a simple system without a controller, so automation is an added cost on top. In the US, the Natural Resources Conservation Service (NRCS) supports drip through its Environmental Quality Incentives Program (EQIP) under practice 441, Irrigation System, Microirrigation. NRCS reports over $535 million obligated for microirrigation from FY2014 to FY2023, and California and Texas received almost three-quarters of it. The practice also requires an irrigation water management plan. Ask your local NRCS office about current payment rates; outside the US, check your regional water or farm agency.

How to choose and set up a system

1. Fix the water first. Test water quality, size the filter for your source, and check pressure at the far end of each zone. Automation will not fix poor uniformity.
2. Map your zones. Count valves, note distances from power and from a mobile signal, and mark which fields move each season.
3. Pick the control level. Start with timers if labour is the problem. Add soil moisture sensors where water cost, leaching or crop quality matter more.
4. Choose the link. Battery and radio units suit fields without power. Solar mesh nodes suit orchards and other large farms with many blocks. Wired or two-wire RTUs suit fixed blocks near a pump house.
5. Plan sensors and calibration. Place probes in representative soil at root depth, in more than one spot per zone, and check readings against a hand sample.
6. Get two quotes and a service plan. Ask each dealer for hardware, software subscription, installation and yearly service costs, and who answers the phone in peak season.

Fertigation through drip lines needs a backflow preventer, and any fertiliser or chemical you inject must be used as the product label allows; follow the label and local rules. Use a licensed electrician for pump and mains wiring where local rules require it.

Where satellite crop monitoring fits

Satellites do not open valves. What they add is a view of every block at once. Vegetation indices from satellite images show where crop vigour is lower than in the rest of the field, which can point to a blocked lateral, a zone that runs short, or a soil patch that dries faster than the one with the sensor. They show a change in the crop, not its cause, so someone still needs to check the spot on foot.

The Farmonaut Satellite + AI Farm Monitoring System gives field-level crop health maps, weather data and irrigation advisories through the Farmonaut web and mobile app. Developers can pull the same data through the API and its developer documentation. Farmonaut also offers tools for fleet management, large-scale farm management, carbon footprinting and product traceability, and satellite data for crop loan and insurance providers.

FAQ

What is an automated drip irrigation system?

It is a drip system whose valves are opened and closed by a controller instead of by hand. The controller follows a timer, soil moisture readings, weather data or a cloud schedule. In the US, drip and other low-flow systems covered 6.43 million open-field acres in 2023 (USDA NASS).

Can I automate the drip system I already have?

Usually, yes. Rivulis notes that many existing hydraulic valves can be fitted with an electric solenoid and connected to a controller. Battery units such as Toro’s Tempus AG-CT run latching solenoid valves without new wiring. Check filters and pressure first.

How much water does automation save?

It depends on what you compare it with. Florida trials from 2003 to 2005, summarised by UF/IFAS, found savings from 11% (on-demand subsurface drip against sprinklers) to 70% (sensor control against farmer practice on tomato). If you already irrigate carefully by hand, expect less.

Do soil moisture sensors need calibration?

Often, yes. The UF/IFAS fact sheet says different sensor types do not perform alike under all conditions, some need a soil-specific calibration, and the number and placement of sensors matter because soil varies across a field.

Is there cost-share for drip automation?

In the US, NRCS EQIP practice 441 covers microirrigation systems, and it requires an irrigation water management plan. In the Florida watermelon assessment, cost-share came from the state agriculture department (FDACS) and the Suwannee River Water Management District, and more than half of the surveyed growers received over $10,000 to buy equipment. Payment rates differ by state, so ask your local NRCS office.

Does satellite monitoring replace soil sensors?

No. Sensors measure water at one spot and depth; satellite images show crop condition across the whole field every few days when skies are clear. Many growers use both: sensors to trigger irrigation, images to find the blocks that need a closer look.
