[USCC] Soil texture analysis lab procedure

[Craig Coker]

Colleagues:

 

Can anyone recommend soil texture testing procedures other than the
Bouyoucos Hydrometer method?  A client of mine is making up manufactured
specialty soils from their compost plus rock fines from a nearby quarry.
Apparently, this texture analysis procedure is giving false readings on Clay
content in the manufactured soil sample due to the turbidity of the water
(the finest of the rock fines) in the hydrometer, which is causing the soil
mix to not meet the landscape architect's spec of no more than 5% clay
content.

 

Many thanks!

Craig
