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.

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
