“…Thus, both PSO and Elovich models were capable of describing the kinetics of H 2 PO 4 − adsorption on volcanic soils. Similar results have been obtained by other researchers for an acid soil [40] and for adsorbents such as biochar [38] and chitosan [41].…”

Engineered nanoparticles (ENPs) present in consumer products are being released into the agricultural systems. There is little information about the direct effect of ENPs on phosphorus (P) availability, which is an essential nutrient for crop growthnaturally occurring in agricultural soils. The present study examined the effect of 1, 3, and 5% doses of Cu0 or Ag0 ENPs stabilized with L-ascorbic acid (suspension pH 2–3) on P ad- and desorption in an agricultural Andisol with total organic matter (T-OM) and with partial removal of organic matter (R-OM) by performing batch experiments. Our results showed that the adsorption kinetics data of H2PO4− on T-OM and R-OM soil samples with and without ENPs were adequately described by the pseudo-second-order (PSO) and Elovich models. The adsorption isotherm data of H2PO4− from T-OM and R-OM soil samples following ENPs addition were better fitted by the Langmuir model than the Freundlich model. When the Cu0 or Ag0 ENPs doses were increased, the pH value decreased and H2PO4− adsorption increased on T-OM and R-OM. The H2PO4− desorption (%) was lower with Cu0 ENPs than Ag0 ENPs. Overall, the incorporation of ENPs into Andisols generated an increase in P retention, which may affect agricultural crop production.

“…In contrast, biochar addition to two acidic soils, an Acrisol and a Ferralsol with pH ( H 2 O ) 5.03 and 4.73, decreased P sorption with increasing pyrolysis temperature. These resultswere confirmed in a study by Ghodszad et al (2021), who alsoreported an increase of P sorption with increasing pyrolysis temperature in an alkaline soil (pH 7.4) after addition of 6% wheat straw-derived biochar, but a decrease in two acidic soils (pH 4.6 and 6.0). The biochars in this study were produced at 300 °C and 600 °C.…”

“…In our study, biochar addition to the Arenosol slightly enhanced maximum PO 3− 4 -P sorption capacity, whereas undiluted biochar induced release of PO 3− 4 -P . Only a few studies have conducted batch equilibrium experiments and derived sorption isotherms to examine P adsorption on biochars, and a very limited number of studies have worked on P adsorption of biochar-soil mixtures at varying pyrolysis temperatures (e.g., Eduah et al 2019;Ghodszad et al 2021). As for other nutrients, most batch experiments were conducted with pure biochars; we only found a few studies that have tested soil/biochar mixtures for their maximum P sorption capacity.…”

Tropical Arenosols may be challenging for agricultural use, particularly in semi-arid regions. The aim of this study was to evaluate the impact of the addition of increasing shares of biochar and clay on the nutrient sorption capacity of a tropical Arenosol. In batch equilibrium experiments, the sorption of ammonium-N ($$\hbox {NH}_{4}^{+}{\text{-N}}$$ NH 4 + -N ), nitrate-N ($$\text {NO}_{3}^{-}{\text{-N}}$$ NO 3 - -N ), potassium ($$\text {K}^{+}$$ K + ), and phosphate-P ($$\text {PO}_{4}^{3-}{\text{-P}}$$ PO 4 3 - -P ) was quantified for mixtures of an Arenosol with increasing shares of biochar and clay (1%, 2.5%, 5%, 10%, 100%) and the unmixed Arenosol, biochar, and clay. The mid-temperature biochar was produced from Prosopis juliflora feedstock; the clayey material was taken from the sedimentary parent material of a temporarily dry lake. Only the Arenosol–biochar mixture with 10% biochar addition and the biochar increased the $$\text {NH}_{4}^{+}{\text{-N}}$$ NH 4 + -N maximum sorption capacity ($$q_{max}$$ q max ) of the Arenosol, by 34% and 130%, respectively. The $$q_{max}$$ q max of $$\text {PO}_{4}^{3-}{\text{-P}}$$ PO 4 3 - -P slightly increased with ascending biochar shares (1–10%) by 14%, 30%, 26%, and 42%, whereas the undiluted biochar released $$\text {PO}_{4}^{3-}{\text{-P}}$$ PO 4 3 - -P . Biochar addition slightly reduced $$\text {NO}_{3}^{-}{\text{-N}}$$ NO 3 - -N release from the Arenosol but strongly induced $$\text {K}^{+}$$ K + release. On the other hand, clay addition of 10% and clay itself augmented $$q_{max}$$ q max of $$\text {NH}_{4}^{+}{\text{-N}}$$ NH 4 + -N by 30% and 162%; ascending clay rates (1–100%) increased $$q_{max}$$ q max for $$\text {PO}_{4}^{3-}{\text{-P}}$$ PO 4 3 - -P by 78%, 130%, 180%, 268%, and 712%. Clay rates above 5% improved $$\text {K}^{+}$$ K + sorption; however, no $$q_{max}$$ q max values could be derived. Sorption of $$\text {NO}_{3}^{-}{\text{-N}}$$ NO 3 - -N remained unaffected by clay amendment. Overall, clay addition proved to enhance the nutrient sorption capacity of the Arenosol more effectively than biochar; nonetheless, both materials may be promising amendments to meliorate sandy soils for agricultural use in the semi-arid tropics.

“…The former fast release was a result of more mobile P, whereas the latter fraction may be evaluated as less labile, which commensurate with the number of sites conquered by P (Kuo & Lotse, 1973). The fast-initial P desorption correlated to the fast degradation of weakly amorphous or crystalline P in the soils as described by Ghodszad et al (2021). The reaction may be decelerated as a result of desorption rate of labile surface P and reduction of crystal dissolution forms of phosphate compounds in the soils (Gorgin et al, 2011;Toor & Bahl, 1999).…”

Phosphorus (P) use in agriculture has witnessed a global increase, leading to significant environmental problems. Nevertheless, the understanding of P kinetics in saline soils amended with nano‐water treatment residuals (nWTR) remains limited. This study aimed to (1) Investigate the impact of different nWTR addition rates (0%, 0.10%, 0.20%, and 0.50%) on the adsorption‐desorption kinetics of P applied to five soils with different salinity levels (1.47–58.50 dS m−1) using batch adsorption experiments. (2) Using different optimization models via Fit Quadratic Model and principal component analysis to predict the optimal utilization of nWTR. The X‐ray diffraction and Fourier transform infrared patterns proposed that the main mechanisms controlling the process are ligand exchange and precipitation. The results revealed that the adsorption level of P in amended soils was rapid, then decreased gradually until reaching equilibrium after 24 h/25°C. The kinetics data were well described by a pseudo‐second‐order model, suggesting a chemisorption‐dependent adsorption process. Increasing soil salinity and nWTR addition led to decline the phosphorus desorption. The application of 0.5% nWTR decreased P‐desorption from 33.95% to 16.22% in the non‐saline soil and from 18.43% to 10.63% in the highly saline soil. principal component analysis distinguished a positive association between P‐adsorbed and nWTR. The optimization models predicted that applying 0.5% nWTR for 965 min maximizes the P‐adsorption rate, reaching 1041 mg Kg−1 in highly saline‐soils. Therefore, nWTR can serve as a cost‐effective and efficient absorbent for mitigating P mobility and reducing its transport in saline soils.
