  1. Amend the soil with fresh plant material or crop remains

    An experiment in 1996 on sandy loam in India (Singh et al. 2005) found higher soil organic carbon under straw incorporation (0.53% of soil sampled) and burning (0.46%), compared to straw removal (0.42%). Soil porosity and soil aggregate size were also higher under straw incorporation (0.4 pores/sample, 0.34 mm) and burning (0.38 pores, 0.28 mm) compared to straw removal (0.37 pores and 0.24 mm respectively). Soil density was lower under straw incorporation (1.6 tm3) compared to straw burning (1.65 tm3) and removal (1.67 tm3). Water infiltration was higher under straw incorporation (0.57 cm/h) compared to straw burning (0.41 cm/h) or removal (0.53 cm/h). Three treatments were applied to a rice Oryza sativa-wheat Triticum aestivum rotation prior to wheat sowing: straw incorporated, straw burned, straw removed. Plot size was not specified. Soils were sampled to 15 cm depth, and soil cores were used to measure water retention.
