  1. Change tillage practices

    A controlled, replicated experiment in 1989-1995 on loam-silt loam in British Columbia, Canada (Lupwayi et al. 2001) found higher bacterial diversity under conventional tillage (4.04 H1 (Shannon diversity index) and 3.94 H1) than zero tillage (3.91 and 3.84 H1 at Rolla and Dawson Creek respectively), during barley Hordeum vulgare planting time. Diversity was higher under zero tillage (3.87 and 3.76 H1) than conventional tillage (3.37 and 3.17 H1 at Rolla and Dawson Creek respectively) during barley harvesting time. There were two sites under continuous barley from 1987 to 1988 then under a barley-barley-canola Brassica campestris rotation from 1989 to 1995. During the rotation phase there were two treatments: conventional tillage (control) and zero tillage. There were four replicates at each site. Soils were sampled during the second barley phase of the rotation in 1995 to 5 cm depth.
