Four methods for extracting nematodes from soil samples were investigated, using soils ranging from predominately sand to mostly clay. These were: The Oostenbrink Flotation Apparatus III, a modified Oostenbrink elutriator, a sugar-flotation technique, and a sieving Petri-dish method. It was found that no one method can be regarded as completely satisfactory for all types of soils. The sugar-flotation technique was more effective with sandy soils, while the other three methods were more effective with clay soils. The sugar-flotation technique proved superior to the other methods for recovery of ring nematodes from all the types of soils used.
