Coir and cocopeat testing
Coir and Cocopeat Testing & Analysis Services in Coimbatore
Greenlink Analytical offers NABL-accredited, highly specialized coir and cocopeat testing services using advanced laboratory instruments and internationally accepted methods. We help manufacturers, exporters, greenhouse growers, hydroponics farms and cocopeat manufacturers ensure their growing media meets global quality standards for pH, EC, nutrient profile, physical properties and contaminants. Accurate, fast and reliable results delivered with detailed reports.
Why Coir & Cocopeat Testing is Important
Unwashed or poorly processed cocopeat can have high salt content (high EC), wrong pH and harmful levels of sodium, chloride or heavy metals that damage roots and reduce yields. Regular testing is mandatory for export consignments (EU, USA, Canada, Australia) and for growers who demand consistent performance from their substrate. Greenlink’s testing ensures your cocopeat is truly “low EC”, “buffered” and safe for sensitive crops.

Parameters and Standards for Coir and Cocopeat Testing and Analysis
| Parameter | Ideal / Permissible Range | Sources of Variation / Contamination | Impact on Plants / Usage | Standard / Reference |
|---|---|---|---|---|
| pH | 5.5 – 6.8 | Natural lignin, washing quality, salinity | Affects nutrient availability; too high/low causes deficiencies/toxicity | ISO 10390, EN 13037 |
| Electrical Conductivity (EC) | 0.2 – 0.8 mS/cm (1:1.5 or 1:5 extract) | Sea water washing residue, salts from coconut husk | High EC causes salt stress, burns roots, poor growth | ISO 11265, EN 13038 |
| Sodium (Na⁺) | < 500 mg/L | Incomplete washing of seawater-used coconuts | Causes sodium toxicity, antagonizes K⁺, Ca²⁺ uptake | FAO, RHP, Australian Standard |
| Chloride (Cl⁻) | < 400–600 mg/L | Sea water residue | Toxic at high levels, osmotic stress, leaf burn | RHP, AS 3743 (Australia) |
| Potassium (K⁺) | 200 – 800 mg/L (moderate) | Naturally high in coconut husk | High K can block Ca/Mg uptake; low K limits growth | EN 13652 |
| Air-Filled Porosity (AFP) | 15 – 30% (v/v) | Particle size, compression, buffering method | Low AFP → root suffocation; high AFP → fast drying | EN 13041, AS 3743 |
| Water Holding Capacity (WHC) | 600 – 900% (by weight) | Fiber vs pith ratio, decomposition stage | Determines irrigation frequency | EN 13041 |
| Total Porosity | > 85% | Particle size distribution | Overall aeration + water retention balance | EN 13041 |
| Bulk Density | 70 – 120 kg/m³ (dry) | Compression level, fiber content | Too high → poor root penetration & drainage | EN 13040 |
| Organic Matter | > 95% | Adulteration with soil, sand, or compost | Lower OM reduces benefits as soilless medium | EN 13039 |
| C/N Ratio | > 80:1 (ideally 100–150:1) | Degree of decomposition | Low C/N → nitrogen immobilization | Common horticultural practice |
| Lignin Content | 30 – 45% | Husk maturity, retting process | Higher lignin → slower decomposition, longer life | Research standard |
| Heavy Metals (Pb, Cd, Cr, Ni, As, Hg) | Below detectable limits or as per regulations | Industrial contamination, dumping site origin | Toxicity to plants and humans via food chain | EU Eco-label, RHP, USDA NOP |
| E. coli / Pathogens | Absent or < 10 CFU/g | Poor composting, animal waste contamination | Food safety risk in edible crops | RHP, EU Regulation 2019/1009 |
| Weed Seeds | Nil | Contamination during processing/storage | Competition with crop plants | RHP, Quality standards |
| Particle Size Distribution | <1 mm: 60–80%, 1–5 mm: 20–40% | Screening quality | Fine particles → compaction; coarse → poor water retention | Manufacturer specs / EN standards |
| Expansion Volume | 12–18 L per kg (compressed block) | Compression ratio, moisture | Indicates true yield from bricks/blocks | Commercial grading |
