The Timing of Application and Inclusion of a Surfactant Are Important

The choice of surfactant is not important for either foliar P uptake or translocation even though different surfactants reduced the contact angle of the fertilizer on the leaves to different degrees.

In agricultural production, foliar fertilization is a critical supplemental method to enhance nutrient uptake efficiency in plants. To maximize the effectiveness of foliar fertilizers, selecting the appropriate surfactant is crucial. Below is a detailed explanation of which surfactants are optimal for foliar fertilizers and how to choose them.

I. The Role of Surfactants

1. Reduce Surface Tension of Water: Surfactants alter the molecular structure of water, enabling it to penetrate plant stomata more easily. This improves the solubility and absorption rate of foliar fertilizers.
2. Increase Fertilizer Utilization: Surfactants disrupt the waxy layer on plant leaves, allowing fertilizers to adhere better to leaf surfaces and reducing runoff.
3. Improve Uniform Distribution: Surfactants help distribute fertilizers evenly across leaves, avoiding localized over- or under-concentration, which could harm plant growth.

II. Commonly Used Surfactants in Foliar Fertilizers

1. Soap-Based Surfactants: Examples include sodium dodecyl sulfate (SDS) and sodium laureth sulfate (SSL). These surfactants have low surface tension and effectively enhance fertilizer absorption.
2. Fatty Alcohol-Based Surfactants: Such as octylphenol polyoxyethylene ether (OP-10) and nonylphenol polyoxyethylene ether (NP-10). These offer good penetration and emulsifying properties, suitable for diverse foliar fertilizer formulations.
3. Non-Ionic Surfactants: Examples include polysorbate series (Tween-80) and polyoxyethylene castor oil (Span-80). These are plant-safe and minimize phytotoxicity risks.
4. Cationic Surfactants: Such as hexadecyltrimethylammonium bromide (CTAB) and hexadecyltrimethylammonium chloride (CTAC). These exhibit strong adsorption and emulsification capabilities, ideal for fertilizers requiring rapid dispersion.

III. Selecting the Right Surfactant

1. Match Surfactant to Fertilizer Type: Different fertilizers pair best with specific surfactants. For example, calcium- or zinc-containing fertilizers benefit from cationic surfactants that form complexes with these nutrients.
2. Consider Crop Type and Growth Stage: Plant species and growth stages influence surfactant needs. Choose surfactants tailored to the crop’s requirements and developmental phase.
3. Prioritize Safety and Eco-Friendliness: In agriculture, prioritize surfactants that are safe for plants, humans, and the environment. Avoid hazardous compounds.

IV. Practical Example

For nitrogen-based foliar fertilization in tomatoes, non-ionic surfactant polysorbate-80 (Tween-80) is recommended. It reduces water surface tension, boosts fertilizer solubility, and promotes absorption without harming tomato plants.

Choosing the right surfactant is vital for optimizing foliar fertilizer absorption and efficacy. By considering factors such as fertilizer type, crop specificity, and safety, farmers can achieve superior results.
