An organic-matter fertilizer with 45% organic matter for rice land preparation, tea-garden soil building and recovery after heavy pruning: better soil and new roots.
HERMEN Jingzuan No.5 is an organic compound fertilizer with NPK 13-1-2 and 45% registered organic matter. Corn-sugar-derived material and sodium humate support white roots, soil structure, nutrient retention and recovery in rice paddies and tea gardens.
Applied at land preparation or as rice basal fertilizer, 45% organic matter supports aggregation, aeration, nutrient retention, white roots and the foundation for lodging resistance.
In tea gardens it supports soil building, post-pruning root recovery and older bushes, followed by a high-nitrogen tea fertilizer when bud stimulation is required.
Developed for Taiwan’s climate, soils and cropping needs. See the full stage-by-stage guide for each crop:

Jingzuan No.5 is recommended at the following growth stages. Open a stage for the full guidance.
Long-cultivated paddies harden at depth, limiting root growth and late-season nutrient uptake. Restoring organic matter at land preparation improves soil structure and aeration, helping rice root deeply.
Full Rice guide →Steep, high-elevation gardens lose organic matter quickly. An annual high-organic-matter basal application loosens soil, revives microbial life and improves nutrient retention — the foundation for vigor and cup quality.
After heavy pruning, root vigor must be restored before bud stimulation. Build soil first, then apply a high-nitrogen tea formula once buds begin to move — otherwise flush is slow and uneven.
The root cause of compaction is usually insufficient organic matter combined with long-term chemical-only fertilization. HERMEN Jingzuan No.5 is an organic compound fertilizer (NPK 13-1-2, 45% registered organic matter) made with natural materials including corn syrup and sodium humate. It is gentle on soil and improves structure by adding organic matter.
White roots indicate new growth, so few of them means low root activity — common where organic matter is depleted and aeration poor. With 45% organic matter and sodium humate, Crystal No.5 improves soil aggregate structure and aeration and activates soil microbes, helping rice root deeply and generate more new roots, which in turn improves late-season uptake and lodging resistance.
Declining budbreak in older bushes is rarely simple nutrient shortage — more often years of harvesting have depleted soil organic matter and weakened roots. Built around 45% organic matter with a gentle 13-1-2 ratio, Crystal No.5 restores soil and roots first; bud stimulation follows. It serves as the foundation for garden rebuilding and vigor recovery.
After heavy pruning most of the above-ground bush is gone, so the priority is restoring root vigor to build reserves for new shoots. The high-organic-matter profile of Crystal No.5 builds soil and protects roots, suiting it as a recovery basal application; once buds begin moving, follow with a high-nitrogen tea formula for a complete program.
The most direct route is a fertilizer high in organic matter that breaks down and is used reliably. Crystal No.5 is registered at 45% organic matter and refined from natural materials such as corn syrup and sodium humate, avoiding the odor and incomplete breakdown of some crude organic fertilizers. Apply at land preparation or as basal fertilizer to build fertility year on year.
