Water-Soluble Fertilizers and Specialty Fertigation Planning
Grade selection, chelates, acid dosing and recipe design — how the fertilizer programme is derived from the water analysis rather than from a catalogue.
Can SeedMatch recommend a fertilizer recipe?
No. SeedMatch is not an agronomy provider and does not issue agronomic recommendations. It sources and compares supplier proposals; the recipe should be set by a qualified agronomist working from your water analysis and crop plan.
Key takeaways
- Start from the water: Bicarbonate determines acid dosing.
- Grade selection: Fully water-soluble grades cost more per tonne than commodity fertilizers but dissolve cleanly, protect emitters and reduce filter maintenance.
- Chelates and specialty products: In high-pH or high-bicarbonate water, EDDHA or DTPA-chelated iron holds availability where sulphate forms do not.
- Recipe stability: Stock-tank separation (calcium apart from sulphate and phosphate), correct dilution ratios and channel accuracy prevent precipitation.
- Plan it numerically: All SeedMatch calculators are indicative only.
A fertigation recipe is not a product list. It is the difference between what the crop needs and what the water already contains — which is why the water analysis, not the catalogue, is the starting document.
Start from the water
Bicarbonate determines acid dosing. Calcium and magnesium already present reduce what must be added. Sodium and chloride set the leaching fraction. Iron and manganese affect both clogging and micronutrient strategy.
Grade selection
Fully water-soluble grades cost more per tonne than commodity fertilizers but dissolve cleanly, protect emitters and reduce filter maintenance. In drip and hydroponic systems the cheaper product is frequently the more expensive decision.
Chelates and specialty products
In high-pH or high-bicarbonate water, EDDHA or DTPA-chelated iron holds availability where sulphate forms do not. Specialty products are justified by chemistry, not by marketing.
Recipe stability
Stock-tank separation (calcium apart from sulphate and phosphate), correct dilution ratios and channel accuracy prevent precipitation. Most "fertilizer quality problems" are actually mixing and dosing problems.

SeedMatch Group is an independent agricultural project sourcing and RFQ platform. We do not operate farms, produce seeds, manufacture fertilizers, manufacture irrigation systems, build greenhouses, provide regulated finance, or connect buyers directly to suppliers through an unmanaged marketplace. Supplier outreach happens only after a commercial project brief is reviewed.

Frequently asked questions
- Can SeedMatch recommend a fertilizer recipe?
- No. SeedMatch is not an agronomy provider and does not issue agronomic recommendations. It sources and compares supplier proposals; the recipe should be set by a qualified agronomist working from your water analysis and crop plan.
- How does SeedMatchGroup handle a requirement like "Water-Soluble Fertilizers and Specialty Fertigation Planning"?
- A buyer submits one private brief through the RFQ builder. Grade selection, chelates, acid dosing and recipe design — how the fertilizer programme is derived from the water analysis rather than from a catalogue. A dedicated sourcing specialist normalises it into a single technical specification, issues it to qualified international manufacturers, integrators and EPC contractors, and returns offers that can be compared line by line on the same scope, lead time and delivery terms.
- What size of project does the platform serve?
- SeedMatchGroup works on commercial agricultural projects from USD 250K upward — greenhouses, irrigation and fertigation, seed processing and production facilities, nurseries, packhouses, cold chain, water treatment, agricultural solar and related infrastructure. Smaller retail or hobby requirements are outside the platform's scope.
- Does the buyer pay anything to use SeedMatchGroup?
- No. Buyers pay no platform fee, subscription or success fee. The platform is compensated by the supply side once a buyer selects a supplier, which is why the shortlist is assembled on technical fit rather than on who pays the most.
