Phosphorus-loaded biochar offers a sustainable alternative by improving soil structure, storing carbon long-term, and supplying plant nutrients, but many biochars remain suboptimal because the governing mechanisms of their properties and phosphorus behavior are not fully understood. This review synthesizes phosphorus-loaded biochar research using machine learning and computational chemistry, emphasizing production, loading, phosphorus release mechanisms, binding control factors, and optimization via organic acids.","Environmental Chemistry Letters  \n[https://doi.org/10.1007/s10311-023-01631-0](https://doi.org/10.1007/s10311-023-01631-0)  \nMachine learning and computational chemistry to improve biochar fertilizers: a review  \nAhmed I.

Alternatively, biochar loaded with phosphorous is a sustainable fertilizer that improves soil structure, stores carbon in soils, and provides plant nutrients in the long run, yet most biochars are not optimal because mechanisms ruling biochar properties are poorly known. This issue can be solved by recent developments in machine learning and computational chemistry. Here wereview phosphorus-loaded biochar with emphasis on computational chemistry, machine learning, organic acids, drawbacks of classical fertilizers, biochar production, phosphorus loading, and mechanisms of phosphorous release. Modeling techniques allow for deciphering the influence of individual variables on biochar, employing various supervised learning models tailored to different biochar types. Computational chemistry provides knowledge on factors that control phosphorus binding, e.g., the type of phosphorus compound, soil constituents, mineral surfaces, binding motifs, water, solution pH, and redox potential. Phosphorus release from biochar is controlled by coexisting anions, pH, adsorbent dosage, initial phosphorus concentration, and temperature. Pyrolysis temperatures below 600 􀀃 C enhance functional group retention, while temperatures below 450 􀀃 C increase plant-available phosphorus. Lower pH values promote phosphorus release, while higher pH values hinder it. Physical modifications, such as increasing surface area and pore volume, can maximize the adsorption capacity of phosphorus-loaded biochar. Furthermore, the type of organic acid affects phosphorus release, with low molecular weight organic acids being advantageous for soil utilization. Lastly, biochar-based fertilizers release nutrients 2–4 times slower than conventional fertilizers.  \nKeywords Climate change 􀀂 Machine learning and computational chemistry 􀀂 Phosphorus-loaded biochar 􀀂 Phosphorus bioavailability 􀀂 Organic acids 􀀂 Biochar-based fertilizer  \nIntroduction  \nBiochar, a carbon-rich material produced through biomass pyrolysis, has garnered significant interest as a potential agricultural amendment and other environmental applications(Farghali et al. 2023;Osmanet al. 2022). Biochar offers promising applications in improving soil quality and nutrient management as a nutrition carrier due to biochar’s unique properties, such as high porosity and surface area. Phosphorus, on the other side, is an essential nutrient required for plant growth and various physiological processes; however, phosphorus availability in soil is limited due to phosphorus’s  \nExtended author information available on the last page of the article  \nhigh reactivity and tendency to form insoluble compounds. Traditional fertilizer practices have been used to combat phosphorus deficiency but have several environmental consequences, including water pollution and soil degradation. As a result, there is a growing need to develop sustainable solutions that increase phosphorus availability while minimizing environmental impacts. The availability of phosphorus in biochar is critical for improving soil fertility and promoting plant growth. However, the phosphorus content in biochar can be relatively stable and not readily available for plant uptake. To significantly improve the bioavailability of phosphorus-loaded biochar, scientists have undertaken a pioneering approach, synergistically combining cuttingedge ","cbCaihsoL2meNE0N","https://ap.wps.com/l/cbCaihsoL2meNE0N","pdf",4462895,1,86,"English","en",105,"# Abstract\n# Introduction\n## Biochar as a soil amendment\n## Phosphorus limitations and fertilizer impacts\n## Rationale for ML and computational chemistry\n# Review Scope and Focus\n## Production methods\n## Phosphorus loading techniques\n## Factors controlling phosphorus release\n## Role of organic acids and optimization\n# Key Mechanistic Insights (from the review)\n## Binding and release control variables\n## Effects of pyrolysis temperature and pH\n## Role of coexisting anions and temperature\n## Surface and pore modifications\n## Comparative nutrient release speed","[{\"question\":\"Why are conventional fertilizers considered inefficient for nutrient use?\",\"answer\":\"Conventional fertilizers lose a major fraction of nutrients and can cause environmental pollution.
