Don't Get Clogged Up: Knowing the rules behind tank mixing can help growers avoid clogging during fertigation

摘要

INJECTING fertilizer through a drip system offers a number of important benefits. However, irri-gators should also be aware that fertilizer can interact with the irrigation water to form precipitates that may clog the drip system. Anhydrous and Aqua Ammonia Injecting anhydrous or aqua ammonia increases the pH of the irrigation water. If the pH increases to more than 7,5, and if the irrigation water contains at least 122 parts per million (ppm) of bicarbonate, calcium carbonate can precipitate.
