In each case the turf was irrigated daily. The soil was Pompano fs. Nitrate-nitrogen at a depth of 60 cm was determined in soil water samples taken daily with ceramic cup devices. Daily moisture flux was determined as X=P+I-E-R, where X is the moisture flux, P the precipitation, I the irrigation, E the evapotranspiration and R the amount of water required to bring the 60 cm profile to field capacity. Flux calculated in this manner was compared with that calculated from tensiometer data. Daily N leaching was calculated as the product of N concentration and water flux. Nitrogen leaching during three week periods frequently ranged from 30 to 60 % of that applied. Leaching was often 50 % greater following single N applications at 3-week intervals than when applied daily through the irrigation system. The data indicated that sizeable reductions in N leaching could be achieved through thoughtful regulation of irrigation." Language: English References: 0 Note: This item is an abstract only!
