Nematodes as indicators of enhanced microbiological activity in a Scottish organic farming system
1994
Griffiths, B.S. | Ritz, K. | Wheatley, R.E.
The presence of spring barley plants increased the numbers of nematodes particularly of plant-feeders compared with fallow plots in a Scottish organic farming system. The addition of farmyard manure (FYM) had no detectable effect on nematode populations but poultry manure (PM) caused a considerable increase. The application of PM also altered the types of nematode present and favoured bacterial-feeders and rhabditids in particular. These changes suggest that PM causes short-term (within a growing season) increases in microbiological activity and nutrient cycling whereas FYM is more likely to bring about long-term changes.
