Abstract
In a survey of 32 oat fields infested with Heterodera avenae Woll. the soil factors affecting the success of the crop at various levels of eelworm density were examined. Of these, water holding capacity was found to be the most important, and after that the phosphorus status. Potassium and organic matter had little effect until they were very low, and pH had no noticeable affect. The proportion of the total soil volume with pore spaces between 30 and 100 in diameter was calculated for each soil and named the Available Pore Space (APS). Low figures for this appeared to have a limiting effect on the build up of cysts when many cereal crops were grown.
