ABSTRACT:
An elutriation apparatus which combines pressurized liquid jets and the low energy air bubble flotation for the separation is described. A manifolded set of multiple apparatus which increases operator efficiency is described. Quantitative separation of roots is achieved by the apparatus by a closed system of mechanical separations using water and air to isolate and deposit roots on a sieve submerged in the water. The method provides a rapid, quantitative and inexpensive method for measuring plant root responses to soil biological, chemical, and physical conditions.
