  1. Grow cover crops beneath the main crop (living mulches) or between crop rows

    A controlled experiment in 1991-2000 on a sandy loam in Champagne, France (Goulet et al. 2004) found that soil particle stability was highest in the topsoil under a grass cover (index rating (K) = 21.7), followed by coniferous bark mulch (rating = 15.2) and poplar bark mulch (rating = 13.6), compared to the control (rating = 10.5). The conifer bark layer also increased stability in soils to 20 cm depth. Three treatments and a control were tested, comprising: a bluegrass Poa pratensis cover between vine rows only; organic mixed mulch of coniferous silver fir Abies alba, Norway spruce Picea excelsa and Scots pine Pinus sylvestri bark between and in vine rows (61 t/ha applied every three years); organic mulch of poplar Populus spp. bark (67 t/ha applied every three years); and bare soil between rows (control). Treatments and controls were tested in 35 x 8 m and 15 x 8 m plots, respectively. Soil under the grass cover was sampled in and between vine rows while the mulch and control treatments were sampled between vine rows only. All soils were sampled to 20 cm depth.

  2. Add mulch to crops

    A controlled experiment in 1991-2000 on a sandy loam in vineyards in Champagne, France (Goulet et al. 2004) found higher soil particle stability in the topsoil under coniferous bark mulch (soil stability index of 15.2) and poplar bark mulch (soil stability index of 13.6) compared to an unmulched control (soil stability index of 10.5). The highest stability was found under a grass cover (soil stability index of 21.7). The conifer bark layer also increased stability in soils. Four treatments were tested, of which three were in 35 x 8 m plots: a bluegrass Poa pratensis cover between vine rows only, organic mixed mulch of coniferous Abies alba, Picea excelsa, Pinus sylvestri bark between and in vine rows (61 t/ha applied every three years), organic mulch of poplar Populus spp. bark (67 t/ha applied every three years), or bare soil between rows (15 x 8 m control plot). Soil under the grass cover was sampled in and between vine rows; the mulch and control treatments were sampled only between vine rows. All soils were sampled to 20 cm depth.
