Smart irrigation proves its worth amid worsening drought

What makes smart irrigation different is not any single device but the way sensing, local conditions and control are fused into one operating loop. Farmers Weekly says irrigation efficiency often remains below 50% because watering is still driven by “the calendar or the clock rather than by what the crop actually needs,” whereas systems that combine root-depth soil sensors, on-site weather stations and decision-support software create a live, field-by-field picture that tells growers whether to irrigate, hold or adjust, turning scattered measurements into actionable prescriptions by crop and zone. As one example, the article says IrriSense 2 enables “up to 40% water savings under optimal conditions,” and Farmers Weekly adds that “soil-moisture-based irrigation control has been shown to cut water use by at least 20% compared with traditional scheduling.”

That convergence matters because it lets water be applied where and when plants can actually use it, instead of uniformly across uneven ground or on fixed schedules. Potato News Today, citing Defra, notes that “Heavier areas can receive too much, while sandier sections may receive too little,” so an August 2026 project at Waldersey Farms and Elveden Estate used soil conditions, crop growth and weather to determine water requirements for individual areas measuring 20 by 20 metres, while Farmers Weekly reports soil-moisture-based control cuts water use and sensor-supported decision systems do so “without sacrificing the crop.”

By late September 2026, the case for precision irrigation was no longer theoretical: it was being validated in drought-hit fields. The Better India reported that “More than half of the country’s area was under dry or drought conditions as of 16 September 2026, according to the latest assessment by IIT Gandhinagar’s India Drought Monitor,” with the share rising from 38.9 percent about a month earlier to 52.5 percent, a backdrop that made on-farm water-saving systems newly urgent and visibly relevant.

In Beed, Maharashtra, farmer Parmeshwar Thorat offered one late-September example of that shift, using drip irrigation on his 1.75-acre farm so water reached plants directly rather than being spread across the whole field. As The Better India described it, the system “delivers it directly to the plants,” helping available water reach the root zone while reducing wastage, and Thorat reinforced that strategy by storing monsoon runoff in a farm pond for the drier months, cutting dependence on groundwater when rains stopped.

The measured savings now span a meaningful range rather than a single headline result. Farms.com reported that “in many cases, farms are cutting water consumption by 20% to 40% through improved management and modern technology,” while also noting that producers are reducing water use “while maintaining or even improving yields,” establishing the lower bound of the chapter’s range and showing that efficiency gains are not necessarily coming at the expense of output.

At the upper end, Bangladeshi agricultural researchers at the Bangladesh Agricultural Research Institute (BARI) in Gazipur ran a dry Rabi-season field trial in 2023 to 2024 using an “Internet of Things (IoT) enabled, sensor-driven drip irrigation system,” where irrigation “began when soil moisture fell to 13.3 percent… and stopped once moisture reached 26.6 percent,” while fertigation on days 20, 40, 60, and 80 was skipped if “electrical conductivity exceeded 0.5 decisiemens per meter.” The trial quantified yield outcomes and reported that the precision system preserved yields with about a 3% gain: the IoT-managed plots produced “30.99 tonnes of marketable fruit per hectare,” “marginally above the 30.08 tonnes from traditional practice, a gain of roughly 3 percent,” and were “statistically similar” to “31.73 tonnes” from drip fertigation, while also cutting fertilizer use.
