| Abstract: | Populations of soil amoebae were estimated throughout two wheat crops and a fallow from wheat rotations suppressive and non-suppressive to take-all. The suppressive pasture-pasture-wheat plot showed higher rhizosphere populations of mycophagous amoebae and higher associations of mycophagous and other amoebae with wheat roots throughout the crop period than the non-suppressive continuous-wheat plot. Populations of mycophagous amoebae were positively and significantly (P = 0.05) correlated with populations of the take-all fungus in both soils, and with soil moisture in the non-suppressive soil. The possible role of mycophagous amoebae in the wheat rhizosphere in suppressive soil is discussed. |
