Field Evidence · Made in China
Real Trial Results — Not Catalog Promises
Data from demonstration sites in Guangdong, Hainan and Yunnan — tropical & subtropical regions with climate close to southern Vietnam. Every figure comes from trials repeated across seasons.

Three Regions, Three Results
Field Data by Crop
Guangdong · 5,000+ ha demo
🍊 Citrus (Mandarin & Pomelo)
Demo areas in Guangdong's main citrus belts (Zhaoqing, Qingyuan, Yunfu). Seaweed actives drive root development and nutrient uptake; polysaccharides & betaine improve drought and cold resilience.
| Indicator | Result |
|---|---|
| Fruit sugar (°Brix) | Up 1.2–1.8 |
| Weight per fruit | Up 8–12% |
| Fruit cracking rate | Down more than 40% |
| Soil organic matter (2 years) | 1.8% → 2.3% |
Hainan · Tropical acidic red soil
🌿 Areca Palm & Tropical Crops
Hainan: tropical climate, heavy rain — acidified soil, nutrients leached. The low-chloride SOP series + seaweed organic matter corrects acidic soil. Extended to pepper, mango and banana.
| Indicator | Result |
|---|---|
| Yellow leaves (chlorosis) | Down more than 60% |
| Yield per tree | Up 15–20% |
Yunnan · Highland vegetables
🥬 Vegetables & High-Value Crops
Yunnan highland vegetable belts (Tonghai, Yuanmou, Chenggong): high-tower organic water-soluble fertilizer + clear liquid granular for precision fertigation.
| Indicator | Result |
|---|---|
| Fertilizer use efficiency | 40% → 65% |
| Vegetable vitamin C | Up 15–20% |
| Nitrate content | Down 30% — meets green food standards |
📉 Chemical Fertilizer Down 20–30%, Yield Stable or Up
Trials in Guangdong, Hainan and Yunnan: chemical fertilizer dose cut 20–30% combined with seaweed biostimulants + microorganisms — yield held or up 5%+, soil organic matter up 0.15–0.3 points/year. Savings of 80–150 yuan per mu (a significant saving per hectare).
For the Vietnam Market
Initial Recommendations for Vietnam's Key Crops
Recommendations based on product characteristics and climate similarity — final verification through joint field demos.
☕ Coffee (Central Highlands)
Seaweed NPK as base fertilizer early season + low-chloride SOP series during fruit filling — Hainan's acidic-soil correction experience maps directly onto acidified basalt soils.
🍈 Durian & Tropical Fruit Trees
High-potassium formulas 13-5-27 / 16-6-28 for flowering & young fruit stages; fully water-soluble 18-6-18 / 15-6-24 through drip systems in intensive orchards.
🌶️ Pepper & Spice Crops
Chelated zinc-boron at 4–5× national standard prevents micronutrient decline in long-term plantations; low-chloride formulas suit chloride-sensitive crops.
🌾 Rice
Balanced NPK for vegetative stage + Blue-Silicon microbial granules for low-organic-matter paddy soils — Hainan's continuous-rice-soil restoration experience fits the Mekong Delta.
