Abstract
Grain size analysis is performed in many soil science laboratories using the pipet method. However, it is still troublesome and time consuming to sample a suspension at a particular depth. In this paper a method is presented in which soil suspensions (clay and silt) were sampled faster and more easily with a syringe inserted horizontally into the suspension through septa. The new syringe method was compared with the pipet method. Both methods were equally accurate but the syringe method has the advantage of being easier to handle and more time efficient. This makes it especially suitable for series analysis. © Williams & Wilkins 1993. All Rights Reserved.
