High pH levels key to spotting micronutrient deficiency

Ontario’s relatively youthful soils are less prone to micronutrient deficiencies, but there are situations where soil characteristics can lead to low levels of key micros in farm fields, says University of Guelph associate professor Dr. John Lauzon. Speaking at the Ontario Soil and Crop Improvement Association’s MicroSmart Deep Dive meeting in Kingston, Ont., Lauzon noted…
