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
