Drip irrigation offers greater water use efficiency than conventional furrow practises, though routine maintenance is required for optimal performance. The continuous of low concentrations (10 ppm) H2O2 stabilized with hydroxyethylidene diphosphonic acid (HEDP) at two (H2O2 Low containing 1 ppb and High ppm HEDP) in drip was evaluated terms emitter, crop yield performance across three species. Emitter flow rates (EFRs) subsurface sugarcane were higher by 16% root intrusion into emitters almost halved Low. For above-ground suspended lines table grape, blockage due to biofouling reduced 50% compared the control or within second year use, extent visible even more. Soil microbiology did not differ markedly between treatments any crops, over four years use. However, soil microbial carbon trial. Yield increases 9, 25, 49% occurred chilli, sugarcane, respectively, treatment control. could be associated increased uniformity supply and/or oxygen plant roots.
