Shengtaifert pitches water-soluble MKP for flowering and fruit set

Tianjin Shengtai Chemical Co., Ltd. is promoting its 100% water-soluble monopotassium phosphate fertilizer for greenhouse fertigation, orchards and other high-value crops. The company says the product is built for rapid dissolution, low impurity levels and reproductive-stage feeding, and is offering technical data and export pricing online.

Why it matters: - Monopotassium phosphate is used when crops need phosphorus and potassium without added nitrogen. - Shengtaifert is positioning its MKP 0-52-34 product for flowering, fruit set and fruit finishing in greenhouse and orchard systems. - The company is also targeting distributors and blenders that need export-ready, fully soluble fertilizer inputs.

What happened: - Tianjin Shengtai Chemical Co., Ltd., also known as Shengtaifert, highlighted its 100% water-soluble monopotassium phosphate on Oct. 19, 2026. - The company said it was established in 2000 and operates as a manufacturer and exporter of crop nutrition products. - Shengtaifert said the product is marketed to agricultural enterprises, fertilizer blenders and commercial distributors worldwide. - The company directed buyers to its export portal for technical data sheets, laboratory certificates and container pricing: the official Shengtaifert export portal. - Shengtaifert also listed a YouTube channel for social media updates: the company's YouTube channel.

The details: - The product is KH2PO4, CAS No. 7778-77-0, with a main assay purity of at least 99.0%. - Shengtaifert said the guaranteed analysis is P2O5 at 52.0% or higher and K2O at 34.0% or higher. - The formulation contains no nitrogen, chloride or sodium, and the salt index is listed at 8.4. - Water-insoluble matter is held at 0.05% or lower, with premium lots below 0.02%. - Shengtaifert said the product dissolves at about 226 g/L at 20°C and up to 835 g/L at 90°C. - An aqueous 1% solution has a pH of 4.3 to 4.7. - Heavy metals are controlled to meet lead at 10 ppm or less, arsenic at 10 ppm or less and cadmium at 5 ppm or less. - The company said the fertilizer is made through thermal neutralization of high-purity phosphoric acid with potassium hydroxide or potassium carbonate, followed by fractional crystallization and centrifugal drying. - Shengtaifert said the product is intended to support floral bud differentiation, blossom retention, fruit enlargement and sugar accumulation after harvest. - The company said typical foliar use rates are 0.2% to 0.5%. - Shengtaifert said the fertilizer is packaged in 25 kg and 50 kg PP bags with PE liners, plus 1000 kg and 1200 kg jumbo bags. - The company said it operates transit warehouse facilities near Tianjin Port and offers mixed Full Container Load shipments with other fertilizers. - Shengtaifert said export arrangements can include FOB and CFR pricing, Certificates of Analysis, SGS pre-shipment inspections, Letters of Credit and Telegraphic Transfer.

Between the lines: - Shengtaifert is presenting MKP as both a crop input and a logistics product, with the packaging, port access and mixed-shipment options aimed at buyers outside China. - The pitch emphasizes technical specifications that matter to fertigation users, especially solubility, low insolubles and low heavy metals. - The company is also trying to differentiate the fertilizer by linking chemistry to crop outcomes such as better bloom retention and fruit quality.

What's next: - Buyers can request technical sheets, certificates and pricing through Shengtaifert's export portal. - International distributors can also use the company's mixed-container model to combine MKP with other water-soluble fertilizers in one shipment. - Shengtaifert is signaling ongoing export sales rather than a one-time product launch.
