Erosion Control on a Steep Sloped Coffee Field in Indonesia with Alley Cropping, Intercropped Vegetables, and No-Tillage

Combined Soil Physical Stress of Soil Drying, Anaerobiosis and Mechanical Impedance to Seedling Root Growth of Four Crop Species

“…The intensity of soil drying and excess moisture will be much stronger in the compacted soil than in the loose soil. Although no-tillage is an effective sustainable cropping system to prevent soil erosion (Iijima et al, 2003a, it often affects crop root development due to the higher mechanical impedance to root elongation (Izumi et al, 2004). Water uptake under such a restricted soil physical environment will also be modified by rooting in shallow soil layer (Zegada-Lizarazu et al, 2006a;Iijima et al, 2007).…”

Water Competition of Intercropped Pearl Millet with Cowpeaunder Drought and Soil Compaction Stresses

“…The compacted soil layer shows higher penetration resistance, causing mechanical stress to root elongation . No-tillage practice also often causes an increase in mechanical stress in the top soil (Iijima et al, 2003;Izumi et al, 2004a and b;Iijima et al, 2005). Besides the negative effect on root elongation in the deep soil layer (Araki and Iijima, 1998, soil compaction hinders water movement and distribution in the soil, limiting the availability of water and nutrients to plants (Rosolem et al, 2002).…”

Productivity and Water Source of Intercropped Wheat and Rice in a Direct-sown Sequential Cropping System: The Effects of No-tillage and Drought

“…The practice of no-tillage has been extensively researched in many cropping systems (Lal, 1989;Oyanagi et al, 1989;Iijima et al, 2003;Izumi et al, 2004a and b) however, it has not yet been tested for direct-sowing rice-wheat sequential cropping. Basic information on the effects of no-tillage on the cropping system is required to solve the abovementioned problems.…”
