Summary
An inoculation trial with S.100 and S.184 white clovers on blanket peat in Wales is described. The scores for clover vigour showed that the establishment and early development of inoculated plants were far superior to the uninoculated. Inoculation increased plant density recorded 2 months after sowing. A technique of nodule sampling and testing isolate effectiveness is described. The counts of nodules and their size distribution indicated a low indigenous rhizobial population with a high proportion of ineffective and intermediate strains. The application of lime encouraged the multiplication of effective strains and increased nodule size. The practical implications of inoculation and the use of such a survey technique is discussed.
