Potassium Carbonate 99.5% Min (K2CO3 / Potash Carbonate) 25kg Bag

Potassium Carbonate K₂CO₃ 99.5% Min Fine Powder – Premium Soluble Potassium Fertilizer Raw Material (25Kg Bag Korea)

Potassium Carbonate 99.5% Fine Powder (chemical formula K₂CO₃) is a high-purity alkaline mineral compound directly imported from South Korea (Made in Korea). Delivering an exceptional soluble potassium nutrient concentration equivalent to approximately 68% K₂O with a minimum purity assay of ≥ 99.5% Min, fertilizer-grade K₂CO₃ 25kg bag is an ideal potassium raw material for modern agriculture. Formulated as an ultra-fine crystalline powder that dissolves 100% clear without residue, it is engineered specifically for premium foliar fertilizer blending, automated fertigation, greenhouse hydroponics, and soil conditioning. It provides crops with immediate, bioavailable potassium nutrition to stimulate blooming, boost fruit enlargement, enhance sugar accumulation (Brix), and ensure uniform crop coloring.

Technical Specification Standards – K₂CO₃ 99.5% Fertilizer Raw Material (Specifications)

Technological Advantages in Fertilizer Blending & Crop Nutrition

• High Potassium Density (~68% K₂O): Supplies an exceptionally high concentration of active, plant-available potassium per unit weight. This saves freight expenses, reduces storage footprint, and optimizes formulation headroom in high-grade liquid and powder fertilizers.
• Alkaline Buffering – Soil De-acidification: Dissolved K₂CO₃ provides gentle alkaline buffering. Upon root-zone application, the carbonate anion (CO₃^2-) neutralizes soil acidity, helping elevate soil pH toward the ideal neutral range to facilitate balanced nutrient uptake.
• Complete 100% Water Solubility: The ultra-fine crystalline powder dissolves rapidly in ambient water to form an optically clear solution with zero insoluble residues. This prevents clogging in precision fertigation injectors, drip emitters, and modern agricultural drone spray nozzles.
• High Purity Profile: Manufactured under rigorous quality control standards, ensuring consistent batch-to-batch chemical performance without heavy metal contamination.

Agricultural Applications & Fertilizer Manufacturing Roles

• Soluble Foliar Fertilizers & Liquid Blends: Acts as the primary soluble potassium source in foliar formulations applied during flowering, fruit development, color maturation, and Brix enhancement stages.
• Drip Fertigation & High-Tech Hydroponics: Supplies bioavailable K⁺ ions through automated irrigation networks for commercial greenhouse crops (melons, strawberries, tomatoes) without leaving chemical scaling on drip lines.
• Soil pH Adjustment Formulations: Applied as a soluble conditioning agent to counter soil acidification in intensively managed agricultural soils.
• Synthesis of Soluble Organic-Potassium Chelates: Reacts smoothly with organic acids (Humic Acid, Fulvic Acid, Amino Acids) to produce fully water-soluble Potassium Humate and Fulvate complexes.

Technical Handling, Blending Guidelines & Storage Protocols

• Tank-Mixing Guidelines: Potassium carbonate solutions are naturally alkaline. Avoid direct concentrated blending with high-ammonia nitrogen compounds or unchelated calcium salts that could form insoluble carbonate precipitates. Always pre-dissolve and dilute in water before mixing with tank additives.
• Hygroscopic Storage Handling: K₂CO₃ absorbs ambient moisture if exposed to air. Partially used bags must have their inner polyethylene liner tightly folded and sealed to maintain a free-flowing powder habit.
• Warehouse Storage Standards: Store in a cool, clean, well-ventilated dry warehouse on elevated pallets away from moisture and isolated from strong mineral acids.

Frequently Asked Questions (FAQ) for Fertilizer Formulators

1. What are the key advantages of using K₂CO₃ in crop nutrition?

K₂CO₃ delivers an exceptionally high potassium concentration (~68% K₂O) and dissolves completely in water without sediment. Furthermore, its mild alkaline buffering property helps condition acidic soils and optimizes the root-zone environment for nutrient uptake.

2. Can K₂CO₃ be safely applied as a foliar spray?

Yes. Due to its high solubility and clean chemical profile, K₂CO₃ is rapidly absorbed through leaf tissues. Because of its alkaline nature, foliar applications should follow agronomic dilution guidelines or be buffered to a physiological pH range prior to field spraying.

3. Does THP Chemical provide trial samples for R&D evaluation?

Yes. THP Chemical provides laboratory testing samples alongside verified batch COAs to fertilizer manufacturers and research facilities to verify solubility and blending compatibility.
