Sulfur granules is an essential element for plant nutrition and its role is superior to phosphorus. Also the role of sulfur in plants, mainly the production of protein, oil and improve the quality of agricultural products. The fourth essential element for nitrogen plants is phosphorus and sulfur potassium. With the difference that plants need this element even more than phosphorus.
Sulfur granules benefits in agricultural soils
The results of the experiments have shown that if sulfur is incorporated with organic matter and thiobacillus bacteria with the correct method and the moisture content is optimal, it can increase up to 60% of the yield of agricultural products. The form of sulfur used by plants is ion sulfate. Therefore, oxidation conditions in the soil should be provided to convert sulfur to sulfate.
To use sulfur, it is necessary to prepare four conditions (moisture, organic matter, deep deposition, and sulfur oxidizing microorganisms) by converting it to sulfate.
Studies also have shown that irrigation water bicarbonate reduces yield. When sulfur is added to the soil, oxidizing bacteria oxidize sulfur to sulfate. This process produces acid and ultimately produces sulfuric acid, and the sulfuric acid proton causes acidification of the soil. The amount of sulfur and its conversion rate to sulfuric acid depends on the amount of moisture, population, and oxidative power of microorganisms in the soil and temperature. The speed of this reaction is slow. Sulfur is an element that requires at least two years to completely convert to sulfuric acid. In this reaction, the solubility of iron, zinc and manganese increases and the yellowish content decreases.
Another role of sulfur granules is to use it to modify salt and alkaline soils. Types of sulfur entering the soil include the use of various fertilizers containing sulfur (enriched fertilizer), sulfur minerals, the use of sulfur-containing modifiers, the addition of organic residues to the soil, and the introduction of sulfur through the atmosphere, pesticides and irrigation water. Sources of sulfur removal from the soil include sulfur uptake by plants and microorganisms, leaching, soil erosion, burning of plant remains and sulfur sublimation from soil.
The role of sulfur in soil and agriculture
The fourth essential element for nitrogen plants is phosphorus and sulfur potassium. With the difference that plants need this element even more than phosphorus. Sulfur is deliberately “involved in the production of amino acids and proteins. And its shortage reduces the product’s quantitative and qualitative performance. On the other hand, the lack of organic matter and the bicarbonate of most irrigation water limits the solubility of high-energy nutrients and micronutrients. And practically, the absorption of these elements is slow. So, the nutrition of sulfur in plants and their consumption is very important.
Benefits of Sulfur Use in Crops and Gardens
- Increasing the solubility of nutrients especially phosphorus, iron, zinc, manganese and, on the other hand, reduction in phosphate and micronutrient fertilizers
- Improving the quality of irrigation water
- Fulfilling the required sulfur content of the plant and increasing yield per unit area
- Correction of PH salts and alkali and calcareous soils
- Reduced nitrate accumulation in agricultural products
- Avoid the spread of soil fungi in terms of the fungicidal properties of sulfur
- Gradual soil sterilization and contributing to environmental health and reducing agricultural use.
Symptoms of sulfur deficiency in plants
In plants, sulfur deficiency appears as pale and jaundice in young leaves and the plant’s lateral parts. Sulfur deficiency also has important effects on plant growth, stems are thin and leaves are complicated. In plants, sulfur deficiency causes the accumulation of non-protein nitrogen, and the use of these plants is harmful and harmful to ruminants. Sulfur deficiency also causes nitrate accumulation in plants that are toxic to animals.
