Nitrogen content of soils at field sites
1981 - IRG/WP 1133
Nine participants in the Collaborative Field Experiment submitted samples for nitrogen analysis to this laboratory as requested by Leightley (IRG/WP/3162). These arrived in a variety of conditions e.g. wet, dried, sterilised and unsterilised and sometimes spent a considerable time in transit. Soils varied in cellular fraction organic matter content, some were obviously sieved prior to postage whil...

Chemostimulatory and chemotropic responses by fungi to preserved and unpreserved wood
1981 - IRG/WP 1134
During experiments to determine the presence of biotic connections between soil and wood at this laboratory, marked chemotropic responses to wood were demonstrated by some wood destroying micro-organism in agar culture. These were shown at some distance from bait, up to 35 mm away, and on some occasions were unaffected by the presence of toxic materials. This paper provides preliminary data on the...
