Complete specifications of sulfur fertilizer
Complete specifications of sulfur fertilizer show that besides nitrogen, sulfur is another substance that is quite important in plant growth. However, knowing about its forms and usage can help farmers to pick and use this fertilizer efficiently.
In this article, we review the complete specifications of sulfur fertilizer to help us in agriculture.
What is sulfur fertilizer?
Sulfur has been essential for plants since its use in the mid-1800s for controlling powdery mildew in vineyards. In 1974, the USA used it to manage fungi in beet crops.
Sulfur, based on the complete specifications of sulfur fertilizer, supports nitrogen metabolism, enzyme activity, and the production of proteins, oils, and vitamins. It helps form amino acids needed for protein, and adequate sulfur use ensures efficient nitrogen use, preventing waste and environmental issues.
Plants absorb sulfur as sulfate (SO₄²⁻), which can leach during heavy rain. To ensure optimal plant health, farmers should supply sulfur as sulfate and elemental sulfur throughout the season.
Key Roles of Sulfur in Plant Growth
- Chlorophyll Formation: Supports photosynthesis and essential compound production.
- Protein & Oil Synthesis: Vital for amino acids and oilseed crops.
- Enzyme Activation: Facilitates biochemical processes.
- Boosting Yields & Quality: Enhances crop output, quality, and market value.
- Crop-Specific Benefits: Improves quality in cereals, tobacco, and forage.
Different forms of sulfur fertilizers
Sulfur fertilizers, like other fertilizers, come in various forms and play a vital role in agriculture. They protect crops and support agronutrition. As a macronutrient, sulfur enhances crop quality and maximizes agricultural benefits.
There are five main types of sulfur fertilizer according to the complete specifications of sulfur fertilizer.
- Sulfate-Sulfur Fertilizers
Quickly dissolve and provide readily available sulfur. Ammonium sulfate (e.g., 20-0-0-24) is common. - Ammonium Sulfate
Can be mixed with other fertilizers but needs uniform blending. - Potassium Sulfate
Ideal for crops like alfalfa needing potassium and sulfur, but not nitrogen. - Elemental Sulfur
Contains 90%-99% sulfur and must be converted to sulfate by soil microbes. Useful for long-term sulfur management when mixed with other fertilizers. - Liquid Sulfur Fertilizer
Acts as both a fertilizer and pest control, managing fungal diseases, repelling pests, and improving saline soil structure.
Sulfur fertilizer chemical properties and specifications
In the complete specifications of sulfur fertilizer, we need to know about sulfur fertilizer technical specifications and its properties. So, they are listed below.
Elemental Sulfur Contains 90–99% sulfur, insoluble in water, and requires microbial oxidation (weeks to months) to become plant-available. It acidifies alkaline soils and oxidizes faster with fine particles. Bulk density: 1.2–1.8 g/cm³.
Ammonium Sulfate (NH₄)₂SO₄ Provides 21% nitrogen and 24% sulfur, dissolves quickly in water, offering immediate sulfur availability, and gradually lowers soil pH. Available in granular or crystalline forms, with a solubility of ~754 g/L at 20°C.
Potassium Sulfate (K₂SO₄) Contains 50% potassium (K₂O) and 18% sulfur, is water-soluble, provides instant sulfate sulfur, and minimally affects soil pH. Solubility: ~110 g/L at 20°C.
Calcium Polysulfide (Liquid Sulfur) in complete specifications of sulfur fertilizer, Calcium polysulfide contains 20-30% sulfur in a liquid form. It acts quickly, serving as both a fungicide and soil amendment. It provides immediate sulfate sulfur and is typically alkaline.
Advantages of sulfur fertilizers
According to the complete specifications of sulfur fertilizer, 5 main benefits of using sulfur fertilizer are listed along with its benefits as top-dressing. Sulfur plays a vital role in plant and soil health by:
- Supporting amino acid, chlorophyll, and vitamin (B1) synthesis.
- Enhancing soil fertility and nutrient availability.
- Promoting crop growth, fruiting, and high-quality seed production, like increased oil in rapeseed.
- Aiding organic matter conversion into humus.
- Boosting microbial activity and acting as a soil conditioner, especially in wet environments.
- Serving as a nutrient, biostimulant, and defense against powdery mildew and pests.
Benefits of Sulfur in Top-Dressing
- Improves Soil: Lowers acidity and prevents erosion.
- Strengthens Roots: Boosts nutrient uptake and resilience.
- Supports Microbes: Enhances soil health and disease protection.
- Adds Resilience: Aids plants in extreme conditions.
- Boosts Yields: Improves crop health and productivity.Bottom of Form
Sulfur fertilizer usage guideline
The complete specification of sulfur fertilizer shows that the best practices for sulfur fertilization are for crops like Alfalfa, canola, corn, cotton, soybean, wheat, and barely.
Sulfur can be applied as foliar sprays, granules, liquids, or mineral fertilizers, tailored to crop needs. Plants absorb sulfur as sulfate (SO₄²⁻), which is soluble but prone to leaching, risking deficiencies.
Elemental sulfur, being water-insoluble, gradually oxidizes into sulfate, providing a steady release. This process lowers soil pH, mobilizes nutrients like phosphorus, iron, and copper, and reduces sodium, improving conductivity and mitigating plant water stress.
Smaller particle sizes and thorough soil mixing accelerate sulfur conversion to sulfate. Broadcast applications are faster than banded ones. Freeze-thaw and wet-dry cycles on the soil surface help break granules, aiding microbial sulfur conversion, while cold, dry soils slow this process.
