When chloride is a critical MKP purchasing requirement, request an explicit specification and appropriate test evidence. Do not translate a marketing description such as “chloride-free” into an analytical assertion of absolute zero.
Separate ingredient design and analytical reporting
The Haifa MKP product page describes a particular phosphorus-and-potassium fertilizer. Its product claims apply to that offering. For an ENVO candidate, request the actual composition statement and chloride specification rather than transferring another producer’s wording.
A method reports within a stated analytical scope. “Not detected” means below the applicable detection criterion under that method, not proof that no chloride exists anywhere in the lot. Record units, sampling, method and reporting limit alongside the result.
| Statement | Evidence to retain |
|---|---|
| No intentionally added chloride source | Defined composition or manufacturing declaration |
| Chloride below an agreed limit | Method-specific specification and relevant result |
| Not detected | Method and applicable detection or reporting threshold |
Choose a limit appropriate to the actual need
The responsible agronomic or formulation team should define the chloride requirement for its water, complete nutrient system and intended use. This article does not prescribe a crop tolerance or legal limit. Avoid demanding an undefined “zero” when a measurable agreed criterion is what the procurement decision requires.
Send ENVO the required chloride expression, method and acceptance threshold with the destination and grade analysis. Confirm what evidence is available before shipment. A precise requirement is more useful than an absolute claim that no laboratory result can support.
