7. Typical Application Case: Vegetable Base & Pepper Greenhouse

Project: Guangdong Province Vegetable Greenhouse, 2023
Fertilizer: 15-30-15 granular fertilizer & best organic granular fertilizer for pepper plants
Background: Soil was saline-alkali with phosphorus deficiency, impacting pepper growth.

• Initial biometric testing using 19-19-19 granular fertilizer showed a 13% increase in stem biomass over local standard NPK blends.
• Switching to 15-30-15 granular fertilizer in combination with best granular organic fertilizer for pepper plants, total fruit count increased by 27.2% (Field Data, HHF Lab 2023).
• Plant resistance to Phytophthora increased – attributed to balanced phosphorus and organic matter. No caking or root burn observed over 9 months.
• Yield per acre: rose from 9.2t→11.6t (26.1% uplift) with consistent blue granular fertilizer supplemental feeding.
• ROI improved by 18.5% (accounting for labor and product cost savings; ISO cost evaluation model applied).
