An initial evaluation of surge irrigation as a management tool for the Burdekin sugar industry : final report 89/7
MetadataShow full item record
Conventional furrow and surge irrigation were compared during the growth of second and third ratoon sugarcane crops on a duplex soil in the Lower Burdekin district. Data collection was severely hampered during this investigation by the prevailing weather. Crop yields produced by both irrigation systems were almost identical. Surge irrigation reduced pumping times by 15.7-23.5% compared with conventional irrigation, thus reducing irrigation costs directly by these percentages. Further savings would result from lower maintenance on pumping equipment. Soil moisture distribution along the furrow and 'out times' for irrigation sets were more uniform for surge irrigation than conventional irrigation.
