Sulfur in agriculture

Sulfur (S) is an essential micronutrient for plant development. Although traditionally classified as a secondary nutrient, its fundamental role in both plant physiology and sustainable agronomic management is now recognized.

Sulfur as a nutrient and its deficiency

Sulfur is essential in determining crop yield and quality. It directly contributes to plant metabolism by being part of essential sulfur-containing amino acids such as cysteine and methionine, which are essential for the synthesis of proteins, enzymes, and vitamins responsible for balanced and healthy plant growth.

In addition, sulfur indirectly contributes to chlorophyll synthesis, improving photosynthetic efficiency. This process promotes greater accumulation of sugars and dry matter in plant tissues, which translates into better yield, texture, and sweetness in fruits.

Sulfur deficiency causes chlorosis in young leaves, delayed growth, and a reduction in the crop protein content. It is important to know that, as a nutrient that is mobile in the soil but immobile in the plant, its deficiencies are not always easy to detect visually without a foliar analysis.

Sulfur as a tool in biotic stress management

Sulfur is an essential ally in modern agriculture, not only for its role in plant nutrition but also for its ability to strengthen the natural defenses of the crop.

Applied in highly soluble and stable forms, it improves nutrient absorption and activates mechanisms such as the production of phytoalexins and lignin, key to resistance to pests and diseases.

Sulfur is essential in the synthesis of phytoalexins, which are antimicrobial compounds produced by the plants in response to pathogen attacks.

This nutrient is essential for the biosynthesis of sulfur amino acids such as cysteine and methionine, direct precursors of the phytoalexins involved in plant defense. By increasing the availability and production of these amino acids, it promotes the fast and efficient synthesis of phytoalexins, thus strengthening the plant induced defensive response to external attacks.

Sulfur also plays a crucial role in the synthesis and accumulation of lignin, which is an essential component of plant cell walls and acts as a physical barrier to pathogen invasion.

When cysteine is degraded by specific enzymes, it generates a gas called hydrogen sulfide (H?S), which works as a signaling molecule in plants. Under biotic stress conditions, hydrogen sulfide (H?S) induces the accumulation of lignin in cell walls, improving the mechanical resistance of tissues and modulating the defensive gene expression.

Sulvian, high-quality sulfur

Plants have natural defense mechanisms to cope with biotic stress, but these may be insufficient against repeated or intense attacks. Therefore, it is crucial to improve their ability to resist damage by using specific products as a preventive measure to strengthen these natural defenses and reinforce these mechanisms.

This is why at Herogra Especiales we offer the fertilizing product Sulvian, that promotes vigorous and healthy crop growth thanks to its high sulfur content, in combination with high absorption nitrogen.

Sulvian leverages these properties, offering an efficient solution that is compatible with sustainable practices, ideal for those seeking yield and plant health by enhancing plant defense mechanisms.

It is an advanced solution designed to provide a high concentration of essential nutrients with a chloride-free, highly stable, and easy-to-use formulation. Its excellent compatibility with other products and the absence of residues makes it an efficient and safe tool for farmers.
