text: For example, if an N fertilizer is applied to Christmas trees as ammonium sulfate, the crop will be well supplied with S, since ammonium sulfate contains 24% S. Other sulfur fertilizers that supply S as sulfate (magnesium sulfate, 14% S; potassium sulfate, 18%S; potassium magnesium sulfate, 23% S; calcium sulfate, 24% S, or gypsum, 19% S), are effective whether incorporated into the soil or applied to the soil surface.
