摘要
The process comprises infiltration of the residues into the soil to the desired depth by irrigation, followed by natural drying. In the case of aq. residues from olive oil prodn. this is followed by one or several irrigations with clean water. The process is carried out in a controlled infiltration area divided out in halves which are used alternately for irrigation and drying. Before commencing the annual infiltration, the sub-soil is cultivated, and after each cycle the surface is scarified.
