Compost Characterisation
For this project, compost analysis is as specified in BS PAS 100:2002, pg 30. The analyses are being performed at Wellesbourne, with the exception of the microbial and heavy metal analyses which will be undertaken by Direct Laboratories, Wolverhampton.
i) Visual inspection
- Texture
- Colour
- Particle size
- Presence of contaminants
- Presence of oversize material
ii) Laboratory characterisation of composts
- Moisture content
- Conductivity
- Organic matter
- Bulk density
- Water-holding capacity
- pH
- Total nutrients
- Microbial analysis including coliforms, Salmonella and Escherichia coli
- Heavy metal analysis
iii) Proximate analysis
- Carbohydrates, phenolics, cellulose, lignin, ash
