Practical guides for farmers
Carrots are picky about water. Not in the way tomatoes or peppers are. Those crops wilt dramatically when they’re thirsty and you get a clear signal. Carrots punish you silently. You won’t know you got it wrong until harvest, when…
Potatoes are picky about water. Not in a dramatic way. They won’t wilt at the first sign of dry soil like lettuce will. But get the moisture wrong and the damage shows up where you can’t see it: underground, in…
Onions are one of those crops that look tough on the outside but are surprisingly needy underground. The root system is shallow. Most of it sits in the top 12 inches of soil, and it doesn’t branch out aggressively to…

East Asia has some of the most interesting drip irrigation stories on the planet, but you wouldn’t know it from the English-language coverage. China is the world’s largest agricultural producer and its biggest irrigation spender. Japan runs absurdly precise greenhouse…
I’ve watched growers blame everything but their injector when a crop goes sideways. The leaves yellow, fruit sets thin, and the instinct is to reach for more fertilizer. A lot of the time, the injector isn’t delivering what the label…
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,…
