1、Use of water soluble fertilizer preservatives

In particular, those liquid fertilizers rich in organic matter and trace elements are more susceptible to microbial contamination and destruction, so preservatives need to be added for protection.

Preservatives are typically added to either minimize microbial growth, as is the case with oral liquids, topicals, and the like, or to prevent microbial growth, as is necessary for sterile preparations such as parenterals, ophthalmics, and oral inhalation solutions.

What Are Water Soluble Fertilizers? All Products and Resources

Water-soluble fertilizers are a highly efficient, fast-dissolving, and 100% water-soluble source of essential plant nutrients. Available as safe powder-blend or liquid fertilizers, precise formulations effectively deliver the nutrients required for optimum growth, yield, and quality.

Water Soluble Fertilizers (WSFs)

Water soluble fertilizers are based on the three essential plant macronutrients: nitrogen (N), phosphorus (P), and potassium (K). Out of the total of sixteen elements necessary to sustain plant life, N-P-K will always be the leading ingredients of water soluble fertilizers.

Preserving Fertilizers and Additives – How to Keep them from Going Bad

The most common explanation to this problem is that your nutrient solution contains a chelating agent – such as EDDHA, EDTA or DTPA – which are organic molecules that wrap themselves around ions.

Water-soluble fertilizer is an efficient and eco-friendly agricultural product that dissolves rapidly in water, allowing plants to absorb its nutrients. To maintain its quality and safety, preservatives are typically added to extend its shelf life.

The primary role of preservatives in water-soluble fertilizers is to inhibit microbial growth and reproduction, thereby ensuring product stability and safety. Commonly used preservatives include:

1. Benzoic Acid Derivatives: Benzoic acid is a widely used preservative that effectively suppresses microbial growth and prevents spoilage. It is often formulated as sodium benzoate, a white, crystalline powder with a strong odor and bitter taste. The typical dosage of benzoic acid preservatives in water-soluble fertilizers ranges from 0.05% to 0.2%.

2. Sorbic Acid Derivatives: Sorbic acid is another common preservative that inhibits microbial proliferation. It is frequently used in the form of potassium sorbate or calcium sorbate, both of which are white, crystalline powders with a slightly sweet taste. The usual concentration of sorbic acid preservatives is 0.05% to 0.3%.

3. Acrylate Esters: Acrylate esters are highly effective preservatives that prevent microbial contamination. They are typically applied as acrylate salts, which appear as colorless or pale yellow, oily liquids. The recommended dosage for acrylate preservatives is 0.01% to 0.03%.

4. Nitrate Salts: Nitrates, such as sodium nitrate or potassium nitrate, are also employed as preservatives. These colorless, crystalline compounds help inhibit microbial growth. Their typical usage level is 0.01% to 0.1%.

In addition to these common preservatives, others like sulfites and phosphates may be used at lower concentrations to partially suppress microbial activity.

the main preservatives in water-soluble fertilizers are benzoic acid derivatives, sorbic acid derivatives, acrylate esters, and nitrate salts. These ingredients effectively extend the product’s shelf life while safeguarding quality and safety. it is crucial to note that excessive use of preservatives may pose health risks. users should follow the guidelines provided in product manuals to ensure the rational application of preservatives.
