Like any essential nutrient, sulphur also has some key functions in plants: 1 Formation of chlorophyll that permits photosynthesis through which plants produce starch, sugars, oils, fats, vitamins and other compounds. 2 Protein production. Sulphur is a constituent of three S-containing amino acids (cysteine, cystine and methionine), which are the building blocks of protein. About 90% of plant S is present in these amino acids. 3 Synthesis of oils. This is why adequate sulphur is so crucial for oilseeds. 4 Activation of enzymes, which aid in biochemical reactions in the plant. 5 Increases crop yields and improves produce quality, both of which determine the market price a farmer would get for his produce. 6 With reference to crop quality, S improves protein and oil percentage in seeds, cereal quality for milling and baking, marketability of dry coconut kernel (copra), quality of tobacco, nutritive value of forages, etc. 7 It is associated with special metabolisms in plant and the structural characteristics of protoplasm.

What is sulfur?
Sulfur is a chemical element of atomic number 16, a yellow combustible non-metal that’s widely found in nature. It’s used in a variety of everyday items — like black rubber, fertilizers, and gunpowder. Sulfur compounds are also responsible for certain foul odors — like the odors that stem from rotten eggs and even skunks. Despite these interesting uses, however, sulfur is still needed by all living things. For example, sulfur is involved in your metabolic processes and is also found in insulin. But why exactly do plants need sulfur?

Secondly, soil tests are designed to tell you what nutrients are in the soil, but it won’t tell you what (or how much) nutrients are in a plant-available form. It would be something like the difference between cows and hamburgers. We eat hamburgers — not cows. This same concept holds true with the nutrients in your soil. Many can be in a form that plants simply can’t absorb. Needless to say, soil tests don’t always give us the information we are looking for.
