Distribution Uniformity in Intensive Horticultural Systems of Almería and Influence of the Production System and Water Quality

The high productivity and efficiency of the use irrigation water that characterizes greenhouse horticultural crops can be affected by poor distribution uniformity. objective this work was to estimate average uniformity (DU) greenhouses in Almería, determining influence quality as well production system on A prospective study carried out which commercial farms were selected used different qualities (groundwater vs. reclaimed) with systems (organic conventional/integrated). Almería 80%. organic presented a drastic DU reduction respect conventional (48% 88%). irrigated reclaimed lower than those groundwater (76% 86%). depth showed slight variations (from 3.2 2.9 mm) depending emitter position, highest values being at head sub-main pipe dripper line lowest end line. very close theoretical 3 mm.
