Practical guides for farmers
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…
Watermelons are 92% water. That fact alone should tell you something about how much irrigation matters for this crop. But plenty of melon farmers still run furrow irrigation and call it good enough, or switch to drip without adjusting their…

Mexico is the world’s largest exporter of avocados, the second-largest exporter of tomatoes, and a powerhouse in berry production. But here’s the problem: the country’s biggest growing regions are running out of water. Michoacán, where roughly 80% of Mexico’s avocados…
