20.5% quick-acting nitrogen with three functional additives and no stone-powder filler, gentle on soil.
A nitrogen fertilizer for rice tillering and tea bud break, with potassium fulvate and other additives that support roots, leaves and looser soil.
HERMEN Jingzuan No.1 Plus supplies 20.5% quick-acting nitrogen with mineral fulvic potassium, lignin ion enzyme and lignin, and no stone-powder filler. It feeds rice tillering and tea flush while caring for roots and soil.
At rice tillering, 20.5% quick-acting nitrogen drives establishment and effective tillers while fulvic potassium and lignin-based factors support roots and nutrient retention.
After tea pruning it supports budbreak and nutrient recovery. The stone-powder-free formulation suits farms prioritizing long-term soil management.
Developed for Taiwan’s climate, soils and cropping needs. See the full stage-by-stage guide for each crop:

Jingzuan No.1 Plus is recommended at the following growth stages. Open a stage for the full guidance.
Tillering determines panicle number and needs readily available nitrogen. Nitrogen alone produces weak, lodging-prone plants, so balancing potassium and caring for the root zone matters just as much.
Full Rice guide →Pre-flush fertilization loads nutrients before buds break, aiming for even emergence. Nitrogen leads, but release must be controlled — ammonium forms leach far less than nitrate on rainy slopes.
Full Tea guide →Insufficient tillering usually reflects short nitrogen supply during the tillering window and weak root activity. HERMEN Crystal No.1 Plus delivers 20.5% premium quick-acting nitrogen for immediate growth, combined with mineral fulvic potassium, lignin ion enzyme and lignin — three functional factors that activate roots and soil biology so uptake efficiency rises and tillering increases.
Earlier closure depends on how quickly nitrogen can be absorbed during tillering. Jingzuan No.1 Plus supplies quick-acting nitrogen for a fast response, while fulvic potassium and lignin improve the root environment so roots extend further and absorb over a greater area, helping the crop cover the field sooner.
Budbreak needs quick-acting nitrogen to start, but long-term reliance on ammonium sulphate acidifies and compacts soil, ultimately impairing root uptake. Crystal No.1 Plus contains no stone powder filler and combines quick-acting nitrogen with mineral fulvic potassium and lignin, supplying nitrogen while activating soil biology — suited to gardens needing rapid flush without sacrificing soil health.
Compaction generally follows insufficient organic matter and long-term reliance on chemical nitrogen alone. Crystal No.1 Plus was designed to address exactly the blind spot of conventional ammonium sulphate — supplying nitrogen while damaging soil. Alongside quick-acting nitrogen it carries mineral fulvic potassium and lignin ion enzyme, activating soil biology and progressively improving structure as you fertilize.
Topdressing is judged on response speed, which requires nitrogen in a form roots can take up immediately. Jingzuan No.1 Plus carries 20.5% quick-acting nitrogen, so greening and growth respond quickly, suited to tillering when nitrogen is needed without delay. Unlike straight quick-release nitrogen, its three functional additives also care for the soil.
