Abstract

The dynamics of mycorrhizae under disturbance created by crop production is not well understood. A 3-year experiment was undertaken on a nutrient-poor and acidic land that had last been cultivated in the early1970s. We observed the effects of cropping spring barley (Hordeum vulgare L,) under four P-fertilizer levels and four levels of lime, in a minimum (rototillage), a reduced (chisel), or a conventional tillage system, on the mycorrhizal receptiveness of the host (maximum level of mycorrhizal colonization, as measured at harvest) and soil infectivitymost probable number method. The host receptiveness decreased with time, while crop yields and soil infectivity increased simultaneously with time. Liming increased mycorrhizal colonization of barley roots andsoil infectivity. P additions decreased root colonization but did notsignificantly affect the most probable number values. Slightly highersoil infectivity estimates were found under reduced tillage.
