Effects of crop rotations of cereals with vetch and fallow on soil nematofauna in Central Spain
Nematologica 44 (1), 63-80
Abstract: The influence of the use of vetch or fallow in rotation with cereals on the dynamics of nematode populations was studied in a field experiment conducted on a luvisol in Central Spain. All the nematodes present in the trial were monitored by seasonal samplings for three consecutive years, starting one year after the first rotation cycle was completed. Vetch in rotation with cereals controlled soil populations of some virus transmitters (Xiphinema pachtaicum and Trichodorus sp.) and the cyst nematode Heterodera avenae. Fallow also controlled X. pachtaicum and H. avenae, as well as Pratylenchus thornei, Ditylenchus dipsaci, Tylenchorhynchus maximus and Tylenchus sp. Other Dorylaimidae and Rhabditidae species seemed to be influenced by vetch and fallow only indirectly. Neither rotation influenced Longidorus profundorum populations. The maturity index based on the nematode fauna was used as a measure of the disturbance in this ecosystem.
