“…The complex geochemistry of sulphate in soil, which is the form in which the nutrient is absorbed by plants, can contribute to explain this effect. Addition of sulphate as phosphogypsum can enhance formation of ionic pairs (Domínguez et al, 2001) which can affect its uptake; nevertheless, very high rates can overcome this effect, in part due to the increase in more soluble sulphates (e.g. Na sulphate) in solution.…”

“…Also, Ca is expected to interact with P by enhancing the precipitation of Ca phosphates which can negatively affect P uptake by plants (Favaretto et al, 2008). However, the use of PG in reclaimed marsh soils from SW Spain has been shown to increase P availability index in soils (Domínguez et al, 2001). Beside this, fluoride, transition metals, boron and trace elements are present in PG (Enamorado et al, 2009).…”

Phosphogypsum (PG) is a by-product of the P fertilizer industry usually valorised as amendment for acidic and sodic soils. This work was aimed to study the effects of PG on nutrient uptake by industrial tomato plants in an originally sodic soil. A completely randomized experiment was performed involving two factors: (i) acidification with nitric acid (mimics cleaning techniques in drip irrigation), and (ii) PG rate (equivalents to 0, 20, 60, and 200 Mg ha–1). The highest PG rate resulted in an increased dry matter yield, which can be ascribed at least in part to an increased water use efficiency. PG decreased K, Mg and P concentrations in shoots, and P and Cu concentrations in fruits. At the highest rate, PG increased B concentration in shoots and total B content in the aerial parts of plants when acid was applied. The highest PG rate also increased Ca concentration in fruits, which can be considered positive in view of reducing the incidence of blossom end rot. The total content of Ni and Mo in aerial parts increased with PG, probably related to a decreased adsorption of these nutrients in soils. Acid application increased the concentration of all micronutrients in shoots and the concentration of Fe, Cu and B in fruits. In conclusion, PG promoted positive effects on B, Ni, Mo, and Ca nutrition, and some negative nutritional effects through antagonisms or affecting nutrient cycling in the soils, which however did not result in decreasing yields, even at a large dose which mimics the cumulative application during 20-30 years. Acid treatments resulted in improved micronutrient nutrition of tomato plants.

“…Salinity and sodicity can affect forms and dynamics of phosphorus in soil (Dominguez et al, 2001). The increase of NaHCO 3 -extractable P with vermicompost may be attributed to the release of humic acid during organic matter decomposition, results in a convert's unavailable soil phosphate into available forms.…”

Water treatment residuals (WTR) and organic amendments can improve both organic wastes recycling and soil reclamation. The present work was carried out to evaluate the effect of vermicompost, when used alone or in combination with WTR at mixed ratios of 2:1 and 1:1 wet weight (Vermi: WTR ), on soil chemical properties of saline sodic soils, and on barley growth (Hordeum aestivm). The results showed that the soil EC, SAR, Cl -and Na + decreased significantly with the application of vermicompost alone and when mixed with WTR. Organic matter, CEC and nutrients available (N, P and K) were increased as the rate of the organic materials increased. The treatment of vermicompost: WTR (2:1 wet weight ratio) at level of 10g kg -1 soil gave the highest grain weight of barley plants compared to other treatments. Based on the results of the current study, the combinations of vermicompost and WTR can are considered as an ameliorating material to reclaim of salt-affected soils and to improve the yield of barley plants. Moreover, it can improve the efficiency of organic wastes and WTR disposal.

“…Reclamation practices involved artificial draining (tile-drains), leaching and soil amendment to reduce Na saturation. Phosphogypsum (PG), a byproduct of the P fertilizer industry, has been effective in reducing sodium saturation in marsh soils from SW Spain (Domı´nguez et al 2001).…”

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
