A collaborative trial on the determination of particle size distribution in soil is described. The analytical method used was that of Avery and Bascombe. Twelve laboratories participated, all of which had considerable experience of the method. Eight soils were collected, divided and distributed by one of the laboratories. The variation in the results is due to errors arising both from the sampling technique and from the analytical method. Estimates of the within and between laboratories variation for the values found in each particle size class for the eight soils are given. Those analyses with high loss are found to give, on average, almost the same particle size distribution as those with low loss.
