Calcium
Looking to dig even deeper into Calcium?
Calcium is a low-key essential nutrient that carries a heavy load in plant growth. Yet, too often it takes a backseat as soil fertility programs are developed for high-yield and high-quality crops. Learn more about how good calcium nutrition can have a profound effect on crops and check out the Calcium section in the complete nutrient management guide.
Symptoms
Symptoms of deficiency can vary across crop species, but similarities exist for how nutrient insufficiency impacts plant tissue color and appearance. Nutrient deficiencies are commonly associated with the physical location on the plant (i.e., whether the symptoms are primarily observed on older versus newly formed plant tissue), but these symptoms can spread as the severity of the deficiency progresses.
