Albert Howard and the mycorrhizal association

► I examine the imperial agricultural science of Albert Howard in India and England. ► Howard emphasised symbiotic association between mycorrhizal fungi and plant roots. ► Howard naturalised his imperial project in his descriptions of mycorrhizal fungi. ► Howard's use of human and fungal intermediaries reveal intercultural discontinuity. ► A focus on discontinuity can reveal limitations in Gieryn's hybrid framework.
