if your crop is fruit trees, our irrigation system(the buried diffuser) could be a good solution because it delivers the water 50cm below the soil suface respecting the heavy soil(50% of clay) water absorption rate(4 litters per hour) . Test have been done during 52 days none stop(days and nights) in a thick heavy soil(4 meters ) to deliver 10 cubic meters of water. the moistened soil bulb has 3 meters diameter . what is important is that the roots system will occupy this bulb and aerate the deep soil layers . The top 50 cm of the soil during the dry season will dry and crack allowing more aeration of deep soil layers. for more information on the buried diffuser visit: www.chahtech.com
