Practical guides for farmers
What satellite NDVI actually tells you that soil sensors miss Soil moisture sensors tell you what’s happening at one point. A tensiometer buried 12 inches deep in row 47 tells you about row 47. Nothing about row 52, the low…
A greenhouse without ventilation is an oven. A greenhouse with the wrong ventilation is an expensive oven. I’ve walked into polytunnels in July where the temperature hit 52°C. Plants weren’t growing, they were cooking. The owner had spent serious money…
The Mendoza River in January runs at about a quarter of its December flow. That’s not a problem you can solve by drilling deeper. It’s just how Andean meltwater works. The snowpack that accumulated from June through September melts fastest…
A soil moisture sensor sitting in the ground is about as useful as a thermometer you never look at. The whole point of buying sensors and hooking them up to a controller is that the system makes decisions for you.…

If you farm anywhere between Bangkok and Bali, you know the rhythm: five months of rain that would drown a cactus, then five months of dry that turns clay into pottery. Nobody installs drip irrigation in Southeast Asia because they…
Turkey grows a lot of things the rest of the world eats. About 75% of the world’s hazelnuts come from its Black Sea coast. It leads global production of cherries, figs, and apricots. It’s the seventh-largest agricultural economy on the…
If you’ve walked through a commercial greenhouse lately, you know the irrigation isn’t one-size-fits-all. Some growers run thin films of nutrient solution down sloped channels. Others pump it through spaghetti tubes to individual pots. A third group fills buckets with…
Blueberries are the diva of the fruit world. They want acidic soil. They want shallow, consistent moisture. They want water that won’t push the soil pH up. And if any one of those things goes wrong, they punish you with…
India pulls more groundwater than any other country on earth, roughly 250 cubic kilometers a year, more than the US and China combined. Most of it goes to agriculture. Wells across Punjab, Rajasthan, and Tamil Nadu are running dry at…
