“…It is also possible that phosphorus anions are desorbed to the soil solution by sulfate anions which take their place on the binding sites (Jaggi et al 2005). The application of nitrogen fertilizers into the soils enhances the activity of microorganisms which increases excreting of organic acids leading to improve the dissolution of insoluble phosphate compounds (Jing et al 2021) as well as the production of phosphatase enzyme which in turn increases phosphorus release resulting from phosphorus mineralization (Horner 2008). The quantity of phosphorus solubility in the presence of ammoniacal nitrogen fertilizers is high in comparison with nitrate nitrogen fertilizers (Sharan et al 2008).…”

“…The distribution of inorganic phosphorus forms is greatly affected by several physical and chemical properties of the soil such as pH, texture, organic matter, calcium carbonate, competing ions, moisture content, and redox potential (Shao et al 2019). Nitrogen applications can have a considerable impact on the transformations and turnover of phosphorus in the soils (Chen et al 2018;Jing et al 2021). The application of nitrogen fertilizer had a greater effect on phosphorus fractions in soil than tillage practices (Zhang et al 2021a, b).…”

The vision of this study is to find a way for increasing phosphorus release from bone char. An incubation experiment was conducted to study the effect of co-applying different nitrogen fertilizer types with bone char (BC) on the availability and distribution of phosphorus in calcium carbonate-rich soil. The experiment contains the following treatments: soil without any nitrogen fertilizer (BC only), soil + ammonium sulfate (BC + AS), soil + ammonium nitrate (BC + AN), and soil + urea (BC + U). Bone char was added to all treatments at a dose of 4 g kg−1 soil. Co-applying bone char with all nitrogen fertilizers caused a significant decrease in pH and increased significantly phosphorus availability in the soil. The concentrations of soil available phosphorus increased from 8.05 mg kg−1 soil for BC treatment to 8.99, 8.90, and 10.16 mg kg−1 soil for BC + AS, BC + AN, and BC + U treatments, respectively, at the end of incubation. Significant increases in soil available phosphorus were observed with increasing incubation periods in all treatments. The effectiveness of the treatments on the soil available phosphorus increase was in the order of BC + U > BC + AS > BC + AN > BC. Nitrogen fertilization treatments significantly increased the NaHCO3-Pi concentrations compared to the BC treatment. Urea application to the soil increased significantly the NaOH-Pi fraction compared to other treatments at day 10 of incubation. Changes in HCl-Pi and Res-P fractions were non-significant in all treatments under nitrogen fertilization. According to the findings, co-applying bone char with nitrogen fertilizers is an agronomic practice that improves phosphorus availability in calcium carbonate-rich soil, thence it is preferable to add urea rather than other nitrogen fertilizers. This study explores a sustainable management strategy to find cost-effective and environmentally friendly alternatives to phosphate fertilizers.

“…These findings suggest a synergistic effect of N fertilization on P uptake by maize. Studies have shown that N application enhances plant P availability and utilization, including stimulating the conversion of organic P forms into inorganic P forms that are more readily taken up by plants [46], reduce the amount of soil iron (Fe) and aluminum (Al) oxides, which are known to adsorb P and make it unavailable to plants [47], and improve P utilization efficiency, P translocation and P translocation efficiency [46]. A field experiment with maize in Zimbabwe demonstrated that increasing N application rates from 0, 40, 80 to 120 N kg ha -1 led to higher total plant and grain P accumulation [48].…”

Crop production in Afghanistan suffers from limited phosphorus (P) availability, which severely hinders national agriculture sustainability. This present study hypothesized that deep fertilizer placement could significantly enhance uptake of immobile P and thus tissue P accumulation and crop yield. A two-year pot experiment growing two maize (Zea mays) hybrid cultivars (Xida-789 and Xida-211) was therefore conducted to test these hypotheses under three contrasting fertilizer placement methods (broadcast, side band, and deep band). In doing so, P concentrations in both maize tissues and soils were compared at 45, 60, and 115 days after sowing (DAS) under nine combinations of nitrogen (N) and P fertilizer rates (kg ha-1: N112P45, N112P60, N112P75, N150P45, N150P60, N150P75, N187P45, N187P60, N187P75). Results have shown that deep band placement significantly increased P uptake efficiency, leading to greater P concentration and accumulation in maize tissues compared to other two fertilization methods. This improved P uptake was attributed to several factors associated with deep placement, including reduced P fixation, enhanced root access to P, and moisture availability for P uptake. Additionally, deep band placement combined with higher N application rates (N187 and N150) further enhanced plant P uptake by promoting P availability and utilization mechanisms. Deep band placement also resulted in significantly higher total soil P, Olsen-P, and P use efficiency than broadcast and side band methods, indicating a more efficient P fertilization strategy for maize that can improve growth and yield. This present study also found positive correlations between P concentration in plant organs and soil Olsen-P, highlighting the importance of adequate soil P levels for optimal plant growth. Overall, our results have showed that deep band fertilizer placement emerged as a superior strategy for enhancing P uptake efficiency, utilization, and maize productivity compared to broadcast and side band placement. This approach can potentially optimize P fertilizer utilization, improve maize growth and yield, while minimizing environmental P losses associated with broadcast applications.

“…At the same time, compared to labile and moderately labile P, non-labile P fractions are less affected by N input (Chen et al, 2018;Liu et al, 2022;Guan et al, 2023). Additionally, while some studies suggest that N input generally increases soil inorganic P and reduces soil organic P fractions (Jing et al, 2021), there are also reports to the contrary . Such variation could be attributed to the different N forms used in these studies (Hu et al, 2022).…”

The availability of soil phosphorus (P), a crucial nutrient influencing plant productivity and ecosystem function, is impacted by continuously increasing nitrogen (N) enrichment, which changes the soil P cycle. The effect of varying forms of N input on soil P dynamics in P-limited karst grassland ecosystems remains unclear. To address this knowledge gap, we conducted a greenhouse experiment to explore the effects of various forms of N addition [Ca(NO3)2, NH4Cl, NH4NO3, Urea] on soil P fractions in these ecosystems, applying two levels (N1: 50 mg N kg−1soil, N2: 100 mg N kg−1soil) of N input in two soils (yellow soil, limestone soil). Results indicated that P fractions in both soil types were significantly affected by N additions, with yellow soil demonstrating a higher sensitivity to these additions, and this effect was strongly modulated by the form and level of N added. High N addition, rather than low N, significantly affect the P fractions in both soil types. Specially, except for Ca(NO3)2, high N addition significantly increased the available P in both soils, following the order: Urea and NH4NO3 > NH4Cl > Ca(NO3)2, and decreased NaHCO3-Pi in both soils. High N addition also significantly reduced NaOH-Po and C.HCl-Po fractions in yellow soil. Additionally, the response of root biomass and alkaline phosphatase activity in both soils to N input paralleled the trends observed in the available P fractions. Notably, changes in soil available P were strongly correlated with plant root biomass and soil alkaline phosphatase activity. Our study highlights that the N addition form significantly influences soil P availability, which is closely tied to plant root biomass and alkaline phosphatase activity. This finding underscores the importance of considering N input form to boost soil fertility and promote sustainable agriculture.
