“…It can be related to the higher clay content in calcareous soil (Table 1). The edge faces of clay minerals behave similar to the Fe and Al hydroxides in the adsorption of P (Prasad and Power, 2000). Al-P concentration in acidic soil similar to the Fe-P was higher than in calcareous soil, but differences of Al-P concentration were not statistically significant.…”

“…Therefore, P is added to cultivated soils worldwide through chemical or organic (e.g., manure and sewage sludge) fertilization. When a water-soluble Phosphorous fertilizer (PF) such as triple superphosphate (TSP) or di-ammonium phosphate (DAP) is applied to soil, immediately after its dissolution the phosphate ions in solution react with Ca, Fe, or Al ions present in soil solution and are precipitated as insoluble compounds, or become adsorbed on surface of clay particles (Prasad and Power, 2000). Chemical P fertilizer is a costly agri-Fractionation of P in submerged soil cultural input for rice farmers in Iran, and sometimes the material is not available.…”

This study was conducted in order to evaluate effects of phosphorous fertilizer (PF)s from sources of triple superphosphate (TSP) and di-ammonium phosphate (DAP) and organic fertilizer (OF)s from sources of cow dung manure (CDM) and municipal solid waste compost (MSWC) on phosphorous (P) fractions include aluminium-P (Al-P), iron-P (Fe-P), Reductant soluble-P (RS-P), calcium-P (Ca-P) and available-P (Olsen-P) fractions under rice cultivation condition. The trials were carried out in calcareous and acidic soils. PFs were added at three levels (10, 20 and 30 mg kg-1) and OFs was applied at the rate of 10 t.ha -1 . Results of this study showed that Ca-P was the predominant form of P in calcareous soil while Fe-P and Al-P were predominate in acidic soils. In calcareous soil, all forms of P under submerged conditions had been increased because of using PFs both alone and in combination with OFs. In acidic soil, significant amounts of P fractions were found only in Fe-P and RS-P fractions. Accordingly, Fe-P fraction increased in 10 mg kg -1 treatment and RS-P increased in MSWC treatment. Among the inorganic P fractions in calcareous soil, only RS-P; and in acidic soil, Ca-P and Fe-P significantly correlated to Olsen-P.

“…There are several causes of soil acidity: the nitrification process, organic matter decomposition, and acid rain contribute to increased soil acidity (Prasad and Power, 1997;Sparks, 2003). Intensive and continuous crop production accelerates the acidification of soil because the conversion of ammonium-based N fertilizer sources to nitrate causes a net H + release, which lowers the soil pH in the plant rooting zone (Tang, 2004;Garvin and Carver, 2003;Prasad and Power, 1997).…”

Hard Red Winter Wheat Cultivar Responses to a pH and Aluminum Concentration Gradient

et al. 2007

Aluminum (Al) toxicity is a major yield‐limiting factor in winter wheat production in many parts of the world. The use of Al‐tolerant cultivars reduces the impact of this problem and is common to the southern Great Plains where wheat is managed as a dual‐purpose crop. However, no quantitative data exist on the Al tolerance ranking of winter wheat cultivars often grown in a dual‐purpose management system. This study was established to classify on a field scale the Al tolerance of common winter wheat cultivars (Ok101, Ok102, 2137, 2174, Jagger, Jagalene, Custer, and AP502CL). Fall forage yield of each cultivar was harvested by hand clipping. Soil samples were collected at the same time and analyzed for pH and Al saturation (Alsat). Grain was hand‐harvested in June of each year from the same rows harvested for forage. Cultivar differences (P < 0.1) were found in forage and grain yields for the Alsat > 30% range. Al tolerance based on grain yield ranked as follows: 2137 > Jagalene = Ok101 > Jagger = 2174 ≥ Ok102 > Custer = AP502CL. Al tolerance based on forage yield ranking was similar to that of grain: 2137 > Ok101 = Jagalene = Jagger > 2174 = Ok102 > Custer = AP502CL. Grain yield seemed to be less affected by Alsat than forage yields. The use of Al‐tolerant winter wheat cultivars may minimize producers' risk of crop loss; therefore, this ranking of Al tolerance should help winter wheat producers make informed decisions if they have acid soils with high Al content and no other remedies available.

“…Some crops such as cotton (Gossypium sp. ), sorghum (Sorghum bicolor) and alfalfa (Medicago sativa) are sensitive to Al toxicity and need liming to nearly zero level of Al-saturation for successful crop growth 33 . Morita et al 34,35 demonstrated that oxalate was a key compound in the Al-tolerance mechanism employed by the tea plant, which detoxifies Al 3+ externally in the rhizosphere.…”
