“…[42] The soil available K was determined by 1 n NH 4 OAc (pH 7.0) method. [43] For assessing the interaction effects of Pb×P, an incubation experiment was conducted for each soil. 2 g soil in triplicate were taken in a series of wide-mouthed test tubes, where four Pb levels of 0, 5, 10, and 20 mg kg −1 and four P levels of 0, 10, 20, and 30 mg kg −1 were added in the form of lead nitrate (Pb (NO 3 ) 2 ) and potassium dihydrogen phosphate (KH 2 PO 4 ), respectively.…”

Phosphorus (P) plays dual role in providing plant nutrition while suppressing lead (Pb) toxicity in soil-plant system. Remediation of lead toxicity with soluble P is a promising low-cost soil rehabilitation technology. An incubation experiment is conducted for assessing the bioavailability of Pb and P under simultaneous application in Pb-laden soils. The treatments consist of four Pb levels, 0, 5, 10 and 20 mg kg −1 soil, and four P levels, 0, 10, 20 and 30 mg kg −1 soil, with five periods of incubation (0, 7, 15, 30 and 60 days) arranged in a 4 × 4 × 5 factorial design. The important physical, physicochemical and chemical characteristics of soil samples are analyzed. Bioavailable P and Pb contents of the soil samples after incubation with Pb and/or P are determined. The results indicate that Pb×P interactions significantly decrease bioavailable soil-Pb concentrations by 38.9-43.9%. Likewise, interactions of Pb×day and P×day significantly reduce soil-Pb concentrations by 33.1-35.1 and 31.8-33.6% at different levels of Pb and P spiking, respectively. A ready reckoner is developed using the antagonism manifestation of Pb and P in soil, which suggests the administration of P doses with respect to Pb-loading and time elapsed to rejuvenate Pb-contaminated soils for healthy crop production.

“…Potassium is an essential macro-nutrient in plant, animal, and human nutrition [ 1 , 2 ]. It is among the exhaustively extracted elements under intensive cropping systems [ 3 , 4 ]. The availability of native and applied K nutrients to plants depends on their buffering and adsorption capacities in the soils [ 5 ].…”
