Citrus
Sulfur has a direct effect on yield. In trials, S has provided yield improvements of between 23-57% on S deficient soils.

Relatively low levels of sulfur are needed in citrus production because removal is low. However, when supplies are limiting, sulfur has a direct effect on citrus yield. There is often enough sulfur in N-P or N-P-K fertilizers, micronutrient formulations or irrigation water to meet crop needs.
Sulfur deficiency symptoms are often very similar to those of N deficiency. The youngest leaves become yellow over the whole leaf. Necrotic lesions may appear which cause early leaf fall. Fruits fail to reach full size and have thicker peels than usual.
