Potassium lignohumate grade GAC-KLHA-S should be evaluated through its documented composition and the intended agricultural formulation. This guide explains the supplier-reported data and the checks needed before irrigation, foliar or soil-use trials. For current supply options and enquiries, use the potassium lignohumate product page.
Grade identity and document scope
The source for the table below is Green Agrochem Potassium Ligno Humate Technical Data Sheet, document GAC-KLHA-S, Rev. 1.0. The corresponding PDF and Word versions contain matching property entries. This table does not describe a separate Grade One or dedicated granule grade; confirm the product code on the quotation, sample and batch documents.
Supplier-reported technical data
| Parameter | TDS value | How to interpret it |
|---|---|---|
| Appearance | Black granules and powder | Confirm the quoted physical form. |
| Water-solubility | 100% | Supplier-reported typical value; test conditions are not stated. Confirm dissolution and filtration in the intended water. |
| Lignohumate content | 75% min | Confirm analytical method and reporting basis. |
| Potassium, as K2O on a dry basis | 12.0% min | K2O-equivalent value, not elemental potassium or an as-supplied assay. |
| Fulvic acids, dry basis | 1.0% min | Confirm the agreed analytical method. |
| Moisture | 15.0% max | Use actual batch moisture for dry-matter calculations. |
| pH | 9–10 | Confirm test concentration, temperature and method. |
Evidence status: the TDS labels these entries as typical production results for reference, not binding specifications, even where it uses minimum or maximum notation. Obtain an agreed current specification and an actual shipment COA before acceptance. Do not treat a typical value as a guaranteed batch result.
Keep potassium and product addition on separate bases
When comparing nutrient contribution, retain the stated dry-basis K2O convention. Do not compare it directly with an as-supplied or elemental-potassium result. Use the batch moisture and verified potassium analysis on consistent bases for formulation calculations. Product addition, nutrient contribution and crop availability are separate questions; a composition table does not establish a field rate.
Plan compatibility and crop-use trials
Start with the intended function, crop-input formulation and application equipment. Use the actual water source and co-formulants. Record dissolution, pH, precipitation, sediment, filtration and storage behaviour. For foliar or irrigation concepts, check the complete diluted mixture and equipment compatibility before expanding the trial.
Request a written starting trial recommendation for this exact grade, including the calculation basis, dilution, application volume and intended crop or soil conditions. Compare with an untreated control and the current practice where appropriate. If evaluating nutrient effects, consider a nutrient-matched comparison. Record adverse crop responses as well as the intended endpoint.
Evaluate performance claims separately from composition
No fixed yield increase is established by this data sheet. The current TDS lists intended soil-conditioning and fertilizer-related applications, but provides no crop-specific protocol, control or numerical yield result. Claims about yield, nutrient retention, stress tolerance, soil pH or crop quality require evidence for the tested formulation and conditions.
For a practical evidence framework, see the plant-growth evaluation and trial guide. Broader process selection is covered in the fertilizer formulation guide. These resources do not establish equivalence between lignohumate and lignosulfonate grades.
Packaging and storage information
GAC-KLHA-S TDS Rev. 1.0 lists 25 kg lined woven bags and 500 kg or 600 kg FIBCs, with other packaging subject to agreement. It states a shelf life of 24 months from production in original unopened packaging, with cool, dry, well-ventilated storage away from moisture and heat. Confirm these terms for the supplied grade and review its current SDS for handling requirements.
Request the matching documents
Send the product code, physical form, intended formulation, water quality, application method, destination market and required tests to info@greenagrochem.com. Request the current TDS, SDS, actual batch COA and representative sample together so the trial and commercial supply use the same grade.
