Effect of soil properties on the forms of inorganic phosphorus in alkaline-calcareous soils of different agroclimatic zones

Grain yield and phosphorus uptake by wheat as influenced by long-term phosphorus fertilization

“…It is also a structural component of metabolically active compounds present in plants. However, its concentration and solubility in soils is low due to its interacting nature, and consequently P is a critical nutrient limiting plant growth (Tekchand and Tomar, 1993;Tomar, 2000;Setia and Sharma, 2007).…”

Successive Application Impact of Some Organic Amendments Combined with Acid Producing Bacteria on Soil Properties, NPK Availability and Uptake by Some Plants

“…Hadad et al, (2015) reported that the available soil P had lowest values in the calcareous sandy soil in spite of the applied levels of some organic wastes which it may be attributed to the high fixation of the released P in the calcareous sandy soil. The soil chemical properties also play a major role for the phosphate fixation in the calcareous soil (Tekchand and Tomar, 1993).…”

A Study on Relationship between Soil and P Adsorption Parameters

“…However, the regression coefficient for clay was only found to be highly significant indicating that the clay content dominated the P adsorption of these soils, Jalali and Sharma (1987) also found 80.5% variation in P adsorption due to clay and organic matter out of which 73% was due to clay content. pH may decrease or increase or have no effect on P sorption depending upon the experimental conditions (Tomar, 2000).Positive and significant correlation between P adsorption and clay content have been reported by several workers Teckchand and Tomar, 1992, Murthy et al, 1996William et al, 1958, Udo and Uzo, 1972and Khalid et al, 1977 …”

“…Organic matter, clay (Jalali and Sharma 1987) and hydrous oxides of Fe and Al (Tekchand and Tomar 1993) in acid soils and calcite and Ca 2+ (Holford et al, 1990) in calcareous soils, play a major role in phosphate sorption. Various other factors that affect the amount of phosphate retained by the soil through adsorption process are pH (Tekchand and Tomar, 1995), temperature and time of contact of phosphorus with the soil.…”
