Sulfur (S) is sometimes referred to as the fourth macronutrient for its benefits next to nitrogen (N), phosphorous (P), and Potassium (K). It is a secondary nutrient that is required for various plant physiological purposes.

Increased sulfur deficiencies have catapulted the demand for sulfur in recent years, which has led to increased use of sulfur in agriculture.

In this article, we'll talk about what makes a great sulfur fertilizer, its role in plants, symptoms of sulfur deficiency in plants, and how sulfur-rich fertilizer can help.

What Makes a Great Sulphur Fertilizer

Just like nitrogen, sulfur is needed in the formation of plant protein. A good sulfur fertilizer should be quickly soluble.

However, sulfur fertilizers have a different range of solubility. For example, Ammonium sulfate and liquid sulfur fertilizer products are highly soluble.

Elemental sulfur, the concentrated form of sulfur, must be oxidized to the sulfate before plants use it.

Elemental sulfur must be finely ground for easy oxidization and high solubility.

Calcium sulfate (gypsum) is also an effective sulfur source found in concentrated and ordinary superphosphate.

The Role of Sulfur in Plants and Why it Matters

The role of sulfur in plants

Sulfur is one of the essential plant nutrients necessary for the growth and development of plants. Some of its other key functions include:

  • Formation of amino acids, proteins, and oils
  • Necessary for chlorophyll formation helps in photosynthesis by which plants produce sugars, starch, fats, oils, and other compounds.
  • It helps in the activation of enzymes which are necessary for biochemical reactions.
  • It enhances nodulation in legumes
  • Increases crop yield and quality of the produce

Nutrient Deficiency Due to Inadequate Sulfur Intake in Plants

Sulfur nutrient deficiency in plants

The plant's need for sulfur is closely related to nitrogen. The relationship between sulfur and nitrogen is evident as both are required for chlorophyll formation. They are also components of protein.

Sulfur is necessary for converting nitrate to amino acids, so crops with inadequate sulfur intake will most likely have lower nitrogen levels.

Apart from its nutritional properties, sulfur improves the soil and helps in fixing phosphorus and nitrogen. Therefore sulfur deficiency will limit crop growth, yield, and quality.

Common Symptoms of Sulfur Deficiency in Plants

Common symptoms of sulfur deficiency in plants

Sulfur deficiency in plants symptoms is similar to nitrogen deficiency. Plants that lack adequate sulfur intake will have pale-yellow or light green leaves.

Unlike nitrogen deficiency, sulfur depletion problems start showing in younger leaves, followed by the older ones.

Also, crops deficient in sulfur are small and with short and slender stalks. They have retarded growth, delayed legumes nodulation, and maturity in cereals.

How a Sulfur Rich Fertilizer Can Help

 

Generally, fertilizers help in plant growth and development. Sulfur-rich fertilizer will help in not only crop growth but also the efficiency of other nutrients.

Sulfur fertilizer can also increase plant quality and yields and result in economic returns to farmers.

Sulfur powder uses in plants go beyond providing sulfur nutrients. It can also be used as a fungicide and pesticide.

What a Quality Sulfur Fertilizer Consists of

Sulfur fertilizers can be categorized into four groups: sulfate fertilizers, fertilizers with elemental sulfur, fertilizers with elemental sulfur and sulfate, and liquid sulfur fertilizer.

Sulfur is also included in fertilizer through a range of sources that include:

  • Potassium Sulfate
  • NPK fertilizer
  • Ammonium Sulfate
  • Organic Matter
  • Phosphoric fertilizer
  • Gypsum or Calcium Sulfate

Sulfate fertilizers provide sulfur as a primary component of multi-nutrient fertilizer in the form of SO4-2. Elemental sulfur fertilizers have concentrated sulfur.

Garden sulfur is a natural and high purity mineral used as plant food and provides sulfur nutrients.

The Best Sulfur Fertilizer
