Foliar Potassium Citrate Complex is a high-purity, potassium-based fertilizer formulated for commercial foliar crop nutrition. It utilizes potassium citrate as an organic acid-chelated potassium source, designed for agricultural programs where targeted potassium is supplied through foliar application during critical crop growth stages.

Where the Product Fits in Crop Nutrition
Foliar potassium is designed as a targeted supplement within an integrated crop nutrition program. It is particularly effective during growth stages when root uptake is limited or plant potassium demand peaks rapidly.
Key Application Stages:
- Vegetative Growth: Supporting cell turgor and structural development.
- Pre-Flowering & Flowering: Enhancing energy transfer and reproductive vigor.
- Fruit Set & Fruit Development: Driving cell expansion and metabolic activity.
- Fruit Filling & Ripening: Promoting sugar translocation, color development, and uniform maturity.
Target Crop Segments
Fruit Crops (Citrus, Grapes, Stone Fruit, Orchards): Enhances fruit size, soluble solids (Brix), skin color, and post-harvest shelf life.
Vegetable Crops (Potatoes, Leafy Greens, Fruiting Vegetables): Prevents transient deficiencies during rapid growth phases and improves yield quality.
Greenhouse & Protected Crops: Ideal for controlled environments requiring ultra-low chloride, precise pH balance, total solubility, and zero nozzle clogging.
Vineyards: Supports balanced vine vigor, cluster development, and optimal berry ripening.
Technical Evaluation & Selection Criteria
Potassium Reporting Basis: Ensure clarity between elemental Potassium (K) and Potassium Oxide (K2O) equivalent when comparing commercial quotes.
Dissolution & Clarity: Test for rapid dissolution, absence of insoluble residues, and solution clarity under local water hardness conditions.
Impurity & Heavy Metal Control: Confirm strict limits on Chloride (Cl), Sodium (Na), Lead (Pb), Arsenic (As), Cadmium (Cd), and Chromium (Cr) to meet destination market regulations.
Physical & Storage Stability: Evaluate liquid grades for phase separation or crystallization at low temperatures (0 - 5 deg C). For solid grades, assess caking resistance and moisture uptake.
Tank-Mix Compatibility: Always perform a standard jar test before mixing with pesticides, biostimulants, or other secondary nutrients.
Quality Assurance & Batch Traceability
Raw Material Qualification: Testing all incoming inputs for purity, heavy metals, and physical specs.
In-Process Quality Control: Continuous monitoring of reaction pH, density, and concentration levels.
Finished Product Testing: Verification of K2O content, solubility, and heavy metal limits prior to release.
Batch Traceability: Every package is labeled with a unique Lot Number tied to complete production records, raw material inputs, and retain samples.
Certificates of Analysis (COA): Provided for every commercial shipment matching the exact batch numbers delivered.

FAQ
Q: Is Foliar Potassium Citrate Complex compatible with standard agricultural sprays?
A: Yes, it is widely compatible with most neutral and slightly alkaline pesticides and fertilizers. However, a standard jar test is always recommended prior to field-scale tank mixing, especially with high-calcium or strongly acidic formulations.
Q: How does potassium citrate compare to potassium chloride or potassium nitrate for foliar use?
A: Potassium citrate is virtually free of chlorides and nitrates, making it significantly safer for sensitive crops and reducing the risk of foliar burn under high-temperature application conditions.
Q: Can custom concentrations or OEM/Private Label packaging be provided?
A: Yes, contract manufacturing, custom nutrient formulations, and private label packaging options are available subject to minimum order quantities (MOQ).
Q: Can I request a sample for laboratory and field testing before bulk purchasing?
A: Yes, representative samples along with the batch Certificate of Analysis (COA) can be dispatched for solubility, pH, compatibility, and small-scale trial evaluations.
Q: Can foliar potassium citrate completely replace soil-applied potassium?
A: No, foliar potassium is designed as a high-efficiency targeted supplement during peak demand periods or stress conditions. It should complement, rather than completely replace, a balanced soil fertility or fertigation program.
