Articles about Water Conservation for agricultural irrigation
If you’ve ever walked through a citrus grove in July and seen fruit splitting on the tree, you already know what inconsistent watering does. Citrus trees are drama queens about moisture. Too dry for a week, then a heavy irrigation,…
You can drop $2,000 on a set of research-grade soil moisture sensors and still get readings that steer you wrong. A vegetable grower in central California installed six sensors across a 20-acre tomato field, followed the data religiously, and ended…
When Spain’s reservoirs hit 36% capacity in early 2024 and Catalonia declared a drought emergency, the response wasn’t panic. It was drip irrigation, and lots of it. Spain already leads Europe in drip adoption, with over 1.8 million hectares under…
Southern Africa doesn’t do things halfway. When it’s dry, it’s properly dry. South Africa’s 2015-2018 drought pushed Cape Town within weeks of running out of water entirely. Zimbabwe’s farmers have watched dam levels drop below 30% in back-to-back seasons. And…
If you grow lettuce, spinach, kale, or salad mixes and you’re still running sprinklers overhead, you’re probably burning money on water and fungicide you don’t need to spend. Leafy greens are the crop category where drip irrigation makes the most…
Most farmers I talk to think about drip irrigation in terms of water saved and yield gained. That math has been settled for decades. But there’s a third number showing up on spreadsheets now, and it’s catching people off guard:…
Soil moisture sensors aren’t new. Farmers have been sticking tensiometers in the ground for decades. What’s changed in the last few years is that you can now network a dozen sensors across a 50-hectare farm, check every reading from your…
I watched a tomato grower in Almería, Spain drain 4,000 liters of irrigation water into a gully behind her greenhouse and thought: that’s not runoff, that’s a second paycheck going down the drain. Greenhouse water recycling isn’t some lab experiment…
The Groundwater Crisis Nobody Wants to Talk About India uses more groundwater than any country on earth. About 250 cubic kilometers a year, roughly a quarter of global groundwater extraction. Most of it goes to agriculture. And the water table…
Why Drip Irrigation Is Catching on in East Africa (And Where It Still Falls Short) I spent a week last year talking to smallholder coffee farmers in Kenya’s Kirinyaga County. Most of them water by hand, carrying buckets or dragging…
