functions of sulfur in plants
It is found in plants as a building material of amino acids, proteins (eg cystine), vitamins, enzymes, some volatile compounds such as mustard oil. It is essential for chlorophyll. It adds flavor to many vegetables. It increases enzyme and vitamin development and activity. It helps to improve root growth and seed production. It helps the plant to be strong and resistant to cold. Sulfur can be in rainwater and they can take sulfur from rainwater to plants. It is also added to some fertilizers, especially low-quality fertilizers, as an additive. The use of gypsum (Gypsum) can also increase soil sulfur levels. Sulfur is an element found in the structure of organic substances. Therefore, it can be found in organic and inorganic forms in the soil. However, organic sulfur constitutes a significant part of the sulfur amount in soils.
sulfur deficiency in plants
Sulfur deficiency in plants has symptoms very similar to nitrogen deficiency. So there is a homogeneous yellowing. Light green leaves are formed in its deficiency. However, the difference is that the yellowing occurs first in the young leaves. In nitrogen, yellowing occurs in old leaves. This is because sulfur cannot be transported from old leaves to young leaves.
