Manage Your Irrigation Water Irrigation increases your opportunities to manage inputs. “In areas of poor infiltration, you can use variable-rate irrigation technology to apply lower amounts of water more frequently, so more water percolates into the soil,” says Ken Ferrie, Farm Journal field agronomist. “You also can reduce the plant population on areas that supply less water. Install moisture sensors in multiple management zones to monitor the water content of various soils,” he says. “In unirrigated corners, lower your yield expectation to the soil’s water-holding capacity and reduce your plant population.” That’s the promise of Variable Input Technology—matching the right amount of inputs to every soil zone to maximize yield and ROI.
