A deficiency in sulfur will affect a plant's protein synthesis, structure, and chlorophyll production, making it an important concern for crops. In recent years, due to the widespread application of high-purity S-free or low-S fertilizers, the control of industrial S-containing waste gas emissions, and intensive agriculture, S levels in the soil have been reduced, and the problem of soil S deficiency has gradually emerged [].Due to the poor mobility of S in plants, the symptoms of S deficiency .

Corn leaves can show striping instead of an overall yellowing, especially when plants are young. 771-775. The parts underneath the leaves may take on a pinkish red or orange color. Protein synthesis requires large amounts of sulfur, which plays an important role in the formation of oils within the seed, and is a constituent of several amino acids and vitamins found in both plants and animals. Plants looks withering. Heavy rainfall and plant growth will both remove sulfur from the soil over time. Sulfur or Sulphur is a very important micronutrient. Sulphur-deficient plants often are pale green, yellowish-green to completely yellow. Other signs of sulfur deficiency include reduced plant height, slower growth rate and lower yield. Etiolation is caused in green plants when they are grown in dark. In the plant nitrogen and sulphur are both essential building blocks for proteins. Sulphur is the constituent of some amino acids and not mobile in plants. Even if a given plant can survive in areas where there's low sulfur in the soil, sulfur deficiency may cause the salinity of the soil to be high enough to impede healthy growth. when the plants are grown in the light. Anything with the words "potassium" or "potash." sulfur (S) Younger leaves turn yellow first, sometimes followed by older leaves. It is easier for the plant to take up sulphate at a lower pH level.

To correct the deficiency apply sulphur fertiliser such as sulphate of potash or ammonium sulphate rather than agricultural sulphur. Plants absorb potassium as an ion, which can be readily leached from soil.Desert soils and water generally have plenty of potassium,so deficiency problems are rare. Sulfur is an essential element in forming proteins, enzymes, vitamins, and chlorophyll in plants, and in nodule development in legumes. These characteristics, which are similar to characteristics of nitrogen-deficient plants, are first observable in the younger . Sulfur deficiency in crops has increasingly been observed over the last 50 years [3,6,7,8]. It is also used in the formation of certain oils and volatile compounds found in the onion and garlic family. 3. Answer.

In potting soil, a sulphur deficiency can occur when the pH is too high, or too much calcium is present. It is easier for the plant to take up sulphate at a lower pH level. Sulphur deficiency will severely reduce the efficient use of nitrogen and limit protein synthesis. Sulphur deficiency is uncommon, but the plant becomes lighter in colour, resembling a pale green when it occurs. Identification. This is also needed in the formation of Chlorophyll. Magnesium (Mg) A macronutrients. Upregulation of the genes for ferritin, RNase, and DnaJ in leaves of rice plants in response to sulfur deficiency. Plant Deficiency.

Sulfur is a component of proteins and bio membranes. Soil tests are valuable only if a correlation was found between the sulfur . If a plant is showing signs of nitrogen deficiencies, the lower (older) leaves will appear yellow, from the leaf tip to the base . Sulphate deficiency in young wheat plants has an early effect on CO 2 assimilation rates and on Rubisco enzyme activity and protein abundance (Gilbert et al., 1997).
