Abstract: Nematodes are microscopic wormlike organisms and soil is an excellent habitat for them to survive. They have different feeding types that are determined by their mouth parts. Amongst the different feeding types there are, beneficial and plant parasitic nematodes. The research focused on on identifying the different nematode feeding types in the soil. The different feeding types were extracted from soil samples from different soils from different crops at different depths. The soil samples were collected from three t different farms producing solanaceous and brassica crops at three different depths. the experiment was conducted in Randomised Complete Block Design in 2 x 3 factorial replicated three times, with farms as blocking factors. The baerman funnel was used in the extraction of the nematodes, the infiltrate was analysed under a microscope, and nematode were identified using mouth parts. however only four feeding types were identified that is the omnivore, bacterivore, fungivore and herbivore. Bacterivores, fungivores and herbivores were abundant in top soil for there is abundant organic matter. Omnivores were abundant in bottom soils, for they are sensitive to soil distubances and nitrogen. There were more beneficial nematodes in the soil samples than plant parasitic, there for that deter mine soil health.
