▶️Case 1: China Henan Wheat Farm (Temperate Continental Climate)
- Background/Challenge: A 300-hectare wheat farm suffered from soil compaction and low nutrient retention, leading to uneven seedling emergence and low yield; traditional powder humic acid caused dust pollution and uneven application.
- Solution/Product Dosage: Adopted our Potassium Humic Fulvic Round Granule, 30kg/ha as base fertilizer (mechanized broadcasting), mixed with urea at 10% ratio; 2 applications per year.
- Quantified Results: Soil compaction reduced by 35%, seedling emergence rate increased from 82% to 96%; wheat yield rose by 13% (from 580kg/ha to 655kg/ha), and fertilizer usage reduced by 18%. We have maintained a 4-year long-term cooperation, with annual order volume growing by 25%.
▶️Case 2: Brazil Soybean Plantation (Tropical Rainforest Climate)
- Background/Challenge: A 400-hectare soybean plantation faced soil acidification and nutrient leaching due to heavy rainfall, resulting in poor root development and low soybean pod setting rate; irregular granules caused equipment jamming.
- Solution/Product Dosage: Used our round granule (28kg/ha) for base application, combined with drip irrigation (20kg/ha) during flowering stage; applied via automated equipment.
- Quantified Results: Soil pH adjusted from 5.2 to 6.0, nutrient leaching reduced by 28%; soybean pod setting rate increased by 15%, yield improved by 14%, and mechanized efficiency increased by 40% (no equipment jamming). We became their exclusive supplier in 2023, with 100% reorder rate.
▶️Case 2: Germany Organic Vegetable Farm (Temperate Maritime Climate)
- Background/Challenge: A 150-hectare organic vegetable farm needed an organic soil amendment that meets EU CERES certification, with no dust pollution and suitable for mechanized operation.
- Solution/Product Dosage: Adopted our round granule (32kg/ha) as base fertilizer, mixed with organic manure; applied via precision broadcasting equipment.
- Quantified Results: Soil organic matter increased from 1.6% to 3.1%, vegetable quality met EU organic standards; sales price increased by 14%, and the farm expanded its order by 30% in the second year. We have cooperated for 3 years, providing customized packaging and timely delivery.
💬Q1: Does your Potassium Humic Fulvic Round Granule meet international organic certification standards?
A1: Yes, it meets EU CERES, US OMRI, and Chinese organic agriculture certifications, supporting customs clearance for global export.
