“…Exchangeable Al was determined by the titration method after Sokolov ( Jakovljevic et al 1985). Speciation of phosphorus was done using sequential extraction procedure: a modified Chang and Jackson method (Manojlovic et al 2007): step I -water soluble P (NH 4 Cl mol/L); step II -Al bound P (NH 4 F 0.5 mol/L); step III -Fe bound P (NaOH 0.1 mol/L); step IV -reducible P (Na dithionite, Na citrate 0.3 mol/L); step V -occluded P (NaOH 0.1 mol/L) and step VI -Ca bound P (H 2 SO 4 0.25 mol/L).…”

Irreplaceability of phosphorus as a necessary macroelement in crop production is due to limited resources and costly processing of ores and immobilization in soil, which force for seeking an alternative sources or the use of waste materials. In this paper, the waste aluminum phosphate from pharmaceutical factory used as phosphate fertilizer and its effects were compared with other phosphorus fertilizers (superphosphate and rock phosphate). Except the analysis of available phosphorus (AL-method) the sequential extraction of phosphorus (modified Chang and Jackson) and sequential extraction of aluminum (modified Tessier) were performed. The experimental plant was mustard (Sinapis alba). The pot experiment was carried out on two soil types: Stagnosol and Vertisol. Application of phosphorus with aluminum phosphate had the same effect as the application of other phosphatic fertilizers in both soil types. In Stagnosol Al-phosphate directly influenced the increase in plant fresh weight by 39% and dry weight by 43% compared to the control, and also decreased the content of mobile Al for 40% and Pb for 47% in plant biomass. Based on these results, the use of waste aluminum phosphate has a potential to be used as a phosphorus fertilizer under given conditions.

“…In acid mineral soils, such as Podzols, P is mostly retained by A l a n d F e o x i d e s b y the ligand exchange mechanism where the OH -or H 2 O groups of sesquioxides surfaces were are displaced by dihydrogenphosphate anions (Simard et al, 1995). In certain soils, this bound is not strictly confined to Al but can bound bind to Si, as well (Manojlovic, et al 2007). However, in the studied Stagnosol, the strong correlation of Al-P with Al extracted in the step 2 (Al II) could be attributed to carbonates and alumosilicates (r=0.998**).…”

“…Fraction of soil P isolated by such a strong reagent may have a high content in soil and mainly is greater than that bound to Al (Manojlovic et al, 2007, Mustapha et al, 2007, ranging between few hundred mg per kilogram. From the chemistry viewpoint, such bounded P is characteristic for the slow-flowing processes involving formation of covalent Fe-P or Al-P bonds on Fe and Al oxide surfaces (Willett et al 1988) which can be an additional source of available P (Beck & Sanchez, 1994).…”

“…Thus, in the conditions determined by reduction processes the reduction of iron Fe 2+ and the breakage of the earlier formed bounds take place, which makes this form of P available for plants. Although this fraction is small compared to other fractions of P in soils, under the oxidized conditions Fe-P represents the dominant fraction (Manojlovic et al, 2007, Mustapha et al, 2007. But under the conditions of soil Al bound P, mg kg -1 applied MAP, kg P ha -1…”

“…The P tied in this manner might be increased in quantity by constant addition of mineral phosphate fertilizer where its total content ranges between few milligrams to tens of milligram per kg soil; i.e. in small amounts from 1% to about 10% from the total mineral P (Manojlovic et al, 2007, Mustapha et al, 2007. Under the alteration of reduced and oxidized conditions that predominate in Stagnosol, this form is chemically tied to the reducible form of P, especially, in the upper soil layer (r=0.890 ** ).…”

AimsBiochar has been used as an amendment to improve soil fertility and increase crop yield. A pot trial and incubation experiment were conducted to evaluate the effects of combined biochar and phosphate fertilizer applications on changes in soil physiochemical properties, photosynthetic parameters, and plant growth of Brassica napus L. in acidic soil.MethodsBiochar (B) was applied at rates (B0: 0%, B1: 2%, and B2: 4% w/w) to the soil, while phosphorus (P) as KH2PO4 was added at P0: 0 mg kg–1 soil, P1: 100 mg kg–1 soil, and P2: 150 mg kg–1 soil. Non‐amended soil served as the control (Ck).ResultsThe study found that the maximum photochemical quantum yield of photosystem II (Fv/Fm) and non‐photochemical quenching were affected by biochar and P fertilizer treatments. The Fv/Fm was significantly lower in the Ck while the highest in B2P1. Compared to the Ck treatment, the electron transport rate and photosynthetic rate were significantly increased under the application of biochar with P fertilizer. Additionally, malondialdehyde content declined by 68.9% when biochar was added with P fertilizer treatments. Furthermore, the plant P content and plant growth parameters were significantly increased. Biochar with and without P fertilizer treatments increased soil pH significantly, compared to the application of P fertilizer alone. Water‐soluble P decreased with incubation time, while Al‐P decreased significantly by 69.9% and 76.4% under B1 and B2 treatments, respectively, compared to CK.ConclusionThe findings revealed a positive effect of the combined application of biochar with phosphate fertilizer on the growth of oilseed rape in acidic soil.
