The distribution of Endogone spores in some Australian and New Zealand soils, and in an experimental field soil at Rothamsted

Some 250 Australian and New Zealand soil samples were examined. Endogone spores were usually more numerous and diverse in cultivated soils than under natural vegetation. It is suggested that the spores develop particularly under conditions of intermittent root growth. In a Rothamsted field soil that had received different manurial treatments (no manure, dung and mineral fertilizer) for over 100 years, spore populations differed greatly. The reliability of the sampling method is discussed. RESP-5871
