The source of sulfur that can be absorbed by plants is elemental sulfur and sulfur found in organic matter. Plants grew sulfur. They receive it in the form of SO4-2 ion. Besides, it was sulfur. With its leaves, it contains SO3 and a small amount of elemental sulfur. They can also take it. Additionally, plants can absorb this element in the form of SO2 gas.

   Sulfur is an element that enters the structure of organic matter. Sulfur is found in plants with sulfur compounds such as cysteine, cysteine ​​and methionine. It is located in the structure of amino acids and combines with them to form proteins. This cycle During this process, sulfur takes part in many enzymatic activities. Sulfur can be easily transported (mobile) within the plant body. However, it is less mobile than N, P, K as it immediately forms various compounds after entering the plant. Sulfur deficiency shows symptoms very similar to nitrogen deficiency. The difference between nitrogen deficiency and sulfur deficiency is that sulfur deficiency, unlike nitrogen, is young. It is seen in the leaves.

The Function of Sulfur in the Plant

· It is found in the structure of some amino acids necessary for protein synthesis.

· It takes part in the synthesis of energy, hormones and some enzymes.

· It accelerates nitrate and carbohydrate metabolism.

· It can be used to lower pH in high pH soils.

Sulfur Deficiency Symptoms

· Sulfur deficiency is very similar to nitrogen deficiency. The difference is that sulfur deficiency, unlike nitrogen, affects young people. It is seen on the leaves.

· The leaves fall and the bud dies.

· Protein synthesis decreases and productivity loss increases.
