▶️Case 1: China Inner Mongolia Saline-Alkali Cotton Farm (Arid Climate)
- Background/Challenge: A 450-hectare cotton farm in Inner Mongolia suffered from severe soil salinization (sodium content high) due to ordinary fulvate flakes; cotton roots rotted easily, yield was low, and soil quality deteriorated year by year.
- Solution/Product Dosage: Adopted our Sodium-Free Potassium Fulvate Flakes II, 7kg/ha for flush application (diluted 1200x), applied every 14 days; 30kg/ha as base fertilizer, mixed with organic manure.
- Quantified Results: Soil sodium content reduced by 22%, salinization was significantly alleviated; cotton root rot incidence dropped from 25% to 4%, yield increased by 14% (from 460kg/ha to 524kg/ha). We have maintained 5-year long-term cooperation, with annual order volume growing by 28%.
▶️Case 2: Middle East UAE Greenhouse Date Palm Farm (Arid, Hard Water)
- Background/Challenge: A 200-hectare date palm greenhouse in UAE used hard water (300mg/L Ca²⁺) for drip irrigation; ordinary fulvate flakes had sodium, leading to soil salt accumulation and date palm leaf yellowing; emitter clogging was frequent.
- Solution/Product Dosage: Used our sodium-free flakes, 8kg/ha for flush application (diluted 1000x), applied every 15 days; added 10% to liquid fertilizer for foliar spray.
- Quantified Results: No soil sodium accumulation, date palm leaf yellowing rate reduced by 90%; no emitter clogging, cleaning labor saved by 25%; date yield increased by 12%, fruit sugar content improved by 1.1 Brix. We became their exclusive supplier in 2022, with 100% annual reorder rate.
▶️Case 3: Netherlands Organic Vegetable Farm (Temperate Maritime Climate)
- Background/Challenge: A 120-hectare organic vegetable farm in Netherlands needed a sodium-free fulvate product to meet EU organic standards; ordinary flakes contained trace sodium, failing to pass certification, affecting product export.
- Solution/Product Dosage: Adopted our Sodium-Free Potassium Fulvate Flakes II, 35kg/ha as base fertilizer, mixed with organic manure; applied via mechanized broadcasting.
- Quantified Results: The farm passed EU CERES organic certification; soil organic matter increased from 1.6% to 3.0%, vegetable yield increased by 13%; export volume increased by 20%, selling price increased by 14%. We have cooperated for 3 years, providing customized packaging and timely delivery.
💬Q1: How do you ensure your Sodium-Free Potassium Fulvate Flakes II is 100% sodium-free?
✅We use high-purity lignite raw materials (no sodium-containing additives) and adopt a special purification process; each batch is tested by a third party, with sodium content strictly controlled at 0%, and test reports are available.
💬Q2: What is the difference between this sodium-free product and your ordinary Mineral Source Potassium Fulvate Flakes II?
✅The core difference is sodium content (this product is 100% sodium-free) and K₂O content (this product ≥15.0%, ordinary flakes ≥10.0%); it is more suitable for salt-sensitive soils and high-end/organic agriculture.
💬Q3: Can the sodium-free flakes be customized in terms of packaging or nutrient content?
✅Yes, we provide customization services, including packaging (25kg bags, jumbo bags, custom printing) and adjusting K₂O/fulvic acid content, tailored to your market and application needs.
💬Q4: Is the product suitable for export, and do you have relevant international certifications?
✅Yes, it has EU REACH, US OMRI, and Chinese organic certifications; sodium-free feature meets global high-end agricultural standards, supporting smooth customs clearance worldwide.
💬Q5: Will long-term application of this product cause any negative impact on soil?
✅No, it is 100% sodium-free, avoids soil salinization; the high humic/fulvic acid content improves soil structure, enhances microbial activity, and is suitable for long-term application in all soil types.
💬Q6. What transportation methods are available for bulk orders, and what is the delivery time?
✅ We provide sea freight, air freight, and land transportation; bulk orders (≥10 tons) are most cost-effective by sea. Delivery time is 7–15 working days, depending on destination.
💬7. Do you provide after-sales technical support for application in saline-alkali soils?
✅ Yes, our professional technical team provides free guidance, including dosage adjustment for saline-alkali soils, application timing, and troubleshooting, to ensure optimal results.
💬Q8: How can I contact you to get free samples for product testing?
✅You can contact our sales team via email, WhatsApp, or the contact form on our website, provide your delivery address and test needs, and we will arrange free sample delivery (1–5kg) within 3 working days.
💬Q9: What payment terms do you accept for bulk orders, especially for new customers?
✅What payment terms do you accept for bulk orders, especially for new customers?
💬Q10: Can the product be mixed with acidic pesticides or fertilizers without chemical reactions?
✅Yes, it has excellent compatibility; its stable chemical properties and pH buffering capacity prevent reactions with acidic additives, ensuring the effectiveness of both the product and mixed materials.
