  1. Grow cover crops when the field is empty

    A randomized, replicated study in 2008-2009 on a sandy-loam soil in Foulum, Denmark (Kadžienė et al. 2011), found a higher number of air spaces in the soil and how connected they are under fodder (animal feed) radish Raphanum sativus, compared to dyer’s woad Isatis tinctoria.. Root growth in the 12-16 cm layer was limited by high soil resistance in directly drilled (-100 kPa) or harrowed (-30 kPa) soil, compared to ploughed soil. A spring barley Hordeum vulgare crop was the main experimental area, replicated three times. It was part of a longer term rotation (not specified). The cover crops were dyer’s woad and fodder radish. Tillage treatments consisted of two 3 × 72.2 m plots within the crop, which were divided into smaller 3 × 13.7 m sub-plots. Tillage was direct drilling, harrowing or ploughing. Soil samples were takento16 cm depth from each sub-plot.
