“…Crop yields on fields irrigated with saline water would be similar to those obtained with fresh water. It was observed, however, that salt would accumulate rapidly in the surface soil and cause production losses where water contained more than 6 g of salt per liter (Yu 1990;Chen 1988;Xiao 1995;Fang and Chen 1997;Monreno et al 2001;Patel et al 2003). Kaledhonkar and Keshari (2006) simulated a 6-year period in saline groundwater irrigation under a wheat-cotton rotation to assess the sustainability of saline water use for crop production.…”

“…Also, an artificial drainage system is usually required to convert marshes to arable land (Hodgkinson and Thorburn 1995;Peck and Hatton 2003), not only to avoid flooding, but also to ensure that the highly saline water table does not encroach into the root zone (Moreno et al 1995(Moreno et al , 2001. Despite their agronomic benefits, tile drains have been found to increase losses of nitrate N through the enhancement of leaching of the soil profile (Gilliam et al 1999;de Vos et al 2000;Kladivko et al 2004).…”

Tile drainage and soil amendments have been found to affect losses of nitrate N from agricultural soils. This work was aimed at measuring nitrate N losses in a tile-drained marsh soil from SW Spain under traditional fertilization and irrigation practices, and how these losses were influenced by the application of soil amendments. To this end, a randomised block experiment with three replications was performed during two consecutive growing seasons-2003 to 2004 with cotton and sugar beet, respectivelyinvolving four different amendment treatments: (1) control without amendment, (2) phosphogypsum (PG), (3) manure, and (4) sugar factory refuse lime (SFRL). Flow-weighted (FW) nitrate-N concentrations in drainage water, estimated as the slope of the regression of the instantaneous nitrate-N flow as a function of drain flow rate, was decreased by PG in some drainage events in the 2003 season and in the four last events of the 2004 season when compared with control without amendment. The increased FW nitrate-N concentrations in drainage from SFRL in comparison to control in a drainage event of 2003 season, and in the four last events of 2004, can be explained by the contribution of N present in the amendment. These effects did not account for significant differences in nitrate-N loss among treatments over the whole season in 2003, when they ranged from 19.3 to 24.9 kg N ha -1 , accounting for 6-8% of applied N, nor in 2004, when they ranged from 4 to 6 kg N ha -1 , accounting for 3-4% of applied N. The decrease in mean FW nitrate-N concentration after the third drainage event in 2003 was not the consequence of the depletion of total soil nitrate-N because soil mineral N was increased on average by 205 kg N ha -1 during the season. The high N extractions by sugar beet and the subsequent decrease in total soil nitrate-N can contribute to explain the decrease of mean FW nitrate-N concentrations along the 2004 season. Greater absolute nitrate-N loss in 2003 than in 2004 was explained by the lower efficiency of the furrow irrigation when compared with sprinkler irrigation. Results also revealed that traditional management of N fertilizer was inadequate: rates applied to cotton were excessive, increasing the risk of N losses not only during the cotton season, but also at the beginning of the following season.Keywords Drainage Á Furrow Á Sprinkler Á Nitrate Á Phosphogypsum Á Manure María Dolores Hurtado died in February 2010.

Reclamation of Guadalquivir river marshes (SW Spain) constitutes a representative example of wetland reclamation in Southern Europe. Nowadays, this is an important area of tile-drained soils (40,000 ha) with an intensive irrigated agricultural production where high fertilizer rates are usually applied. In tile-drained soils, flow through macropores or cracks, which connect the nutrient rich topsoil with drain lines, can be an important pathway for nutrient transfer from soil. In order to study P loss in these soils and how it is affected by soil amendment usually applied in the zone (phosphogypsum and manure) an experiment was performed during two consecutive growing seasons on a reclaimed marsh soil from the Guadalquivir Valley. In the first season (1998)(1999), sugar beet (Beta vulgaris L.) was grown under sprinkler irrigation at a rate of 2.5 mm h À1 ; in the second (2000), cotton (Gossypium hirsutum L.) was grown under furrow irrigation at 8-10 mm h À1 . The amendments applied included manure (30 Mg ha À1 ), and phosphogypsum (13 and 26 Mg ha À1 ). Drainage events were recorded, and water samples collected and analyzed for total P (TP), dissolved total P (DTP), and dissolved reactive P (DRP). Total P in drainflow ranged from 0 to 0.818 mg l À1 in the 1998-1999 season and from 0 to 0.565 mg l À1 in the 2000 season. The major P form in drainflow was DRP, which accounted for about 50% of TP in the two growing seasons (the mean DRP concentration was 0.068 mg l À1 in 1998-1999 and 0.043 mg l À1 in 2000). Dissolved organic P accounted for a higher portion of DTP in the first season (37%) than in the second (13%). A larger load of phosphorus was observed on plots receiving manure. This treatment significantly increased (P < 0.05) the cumulative drainflow during the 1998-1999 growing season (sprinkler irrigation, low drainflow rates). This is consistent with the increased losses of TP, DTP, DAHP, and DRP resulting from this treatment in this growing season. In the following season, DTP loading were significantly increased by manure (P < 0.05). This seems to be related mainly to significantly increased DOP losses (P < 0.01), particularly during the first drainage event. The higher fraction of applied water was lost by drainage under furrow irrigation (high drainflow rates) is consistent with the high TP load during the 2000 growing season (199-285 g ha À1 ) relative to the 1998-1999 season (20-59 g ha À1 ). This difference in P losses was much greater than those resulting from amendment of the soil.Abbreviations: DAHP -dissolved acid hydrolyzable P; DOP -dissolved organic P; DRP -dissolved reactive P; DTP -dissolved total P; PG -phosphogypsum; PP -particulate P; TP -total P
