How Water Soluble Fertilizers (WSF) Work

How Water-Soluble Fertilizers Work and Why High-Quality Chelates Make All the Difference

Water-soluble fertilizers are an exceptionally versatile choice for growers, landscapers, and horticulturists who require rapid and efficient nutrient delivery. Unlike controlled-release or slow-release products—which distribute their nutrients gradually over time—water-soluble formulations dissolve instantly upon contact with water. This immediate availability allows crops to absorb vital macro- and micronutrients without delay, promoting quick response and vigorous growth. At Mivena, we have developed our water-soluble fertilizers with meticulous attention to solubility, purity, and stability, ensuring reliable results under a wide range of growing conditions.

Benefits of Water-Soluble Fertilizers

Rapid Nutrient Uptake
Because these fertilizers dissolve completely in water, plants can access essential elements as soon as the solution reaches their root zone. This helps prevent nutrient deficiencies and supports consistent, healthy development.

Customizable Feeding Programs
Water-soluble fertilizers offer unparalleled flexibility. You can fine-tune both the concentration and the composition of your feeding solution to match specific growth stages or environmental factors. Whether you need a higher nitrogen content during vegetative growth or a balanced formula during flowering, adjustments can be made swiftly.

Reduced Risk of Nutrient Lock-Out
By supplying nutrients in a form that is immediately accessible to roots, you minimize the chance of nutrient build-up or interactions that render key elements unavailable. This translates into more efficient nutrient utilization and reduced risk of salt accumulation.

Simplicity and Convenience
Mivena’s water-soluble line is designed for hassle-free use: it dissolves readily and leaves minimal residue. This ease of application makes water-soluble fertilizers particularly suitable for fertigation systems or foliar feeding programs.

The Crucial Role of Chelates

While macronutrients—nitrogen (N), phosphorus (P), and potassium (K)—draw the most attention, micronutrients such as iron, zinc, manganese, and copper are equally essential for robust plant growth. However, these trace elements can become chemically “locked” in soils with high or fluctuating pH levels, rendering them inaccessible to plants. Enter the chelates: specialized compounds that bind to micronutrients and shield them from unfavorable soil interactions.

Several types of chelates are commonly used, each with its own advantages:

EDTA (Ethylenediaminetetraacetic Acid)
This well-known chelate is effective in slightly acidic to neutral conditions. It maintains good solubility and is cost-effective, making it a reliable choice for many standard agricultural applications.
DTPA (Diethylenetriaminepentaacetic Acid)
Offering enhanced stability at moderately higher pH levels, DTPA is especially beneficial for crops that struggle to access iron and manganese in less acidic soils.
EDDHA (Ethylenediamine-N,N′-bis(2-hydroxyphenylacetic Acid))
Renowned for its superior performance in alkaline conditions, EDDHA keeps iron soluble even in soils with significantly elevated pH. This makes it ideal where iron chlorosis (yellowing leaves) is a persistent threat.
EDDHS(A)
A variant of EDDHA, EDDHS(A) also excels at preserving iron and other trace elements in challenging conditions, providing broad-spectrum stability across a wide pH range.

At Mivena, we carefully select and blend these various chelates to create nutrient solutions that remain available to the plant rather than binding with other elements in the soil or water. This ensures that your crops receive a balanced spectrum of vital micronutrients at the precise concentration needed for optimal growth.

Compatibility of Sulfate and Calcium-Based WSF Formulations

One important consideration when working with water-soluble fertilizers involves the compatibility of sulfate and calcium-containing products. When these two components are mixed in the same solution, they can readily form precipitates, reducing both solubility and nutrient availability. To help growers avoid such pitfalls, we’ve created a clear compatibility chart outlining which Mivena WSF formulations can be safely combined for maximum efficacy and minimal risk of clogging or nutrient lock-out.

Why Pair WSF with CRF?

Although water-soluble fertilizers excel at delivering nutrients quickly and precisely, we’ve found that they often work best when integrated with a controlled-release fertilizer (CRF) regimen. The CRF ensures a steady baseline of nutrients throughout the growth cycle, while the WSF can be applied at critical stages or in response to changing conditions. This complementary approach not only enhances plant performance but also helps prevent under- or overfeeding, creating a balanced program tailored to each crop’s specific needs.
