Why are nematodes agriculturally very important?

Nematodes are the abundant soil microfauna. Being predatory and saprophytic in nature they cause a loss of vigour of the root system. For this reason soils rich in nematodes become liable to diseases also. The damage to crops done by them may be controlled by crop rotation, summer follow and ploughing, use of organic manures and oil cakes.
