A soil management technique to enhance lateral infiltration (subbing) in permanent raised beds

摘要

Permanent raised beds (PRBs) are less susceptible to poor subbing in Australian Vertosol due to prolonged irrigation times and faster subbing in cracks. In contrast, subbing was very poor in sandy clay loam soil. This study revealed enhanced lateral subbing with blade ploughing. However, additional measures of irrigation optimisation for improved infiltration opportunity time and/or water depth in furrow can be beneficial in sandy clay loam soil.
