ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(8), P. 2054 - 2067

Published: July 16, 2024

Herein, a ball-milled composite mineral derived from shell powder and phosphate rock (BSPR) was innovatively coupled with smooth vetch (SV) planting to remediate Cd-polluted soil. The results showed that BSPR SV could reduce the bioavailability of Cd in soil by 68.1%, which 2.2 3.4 times those (31.1%) (20.0%) alone, respectively. outstanding passivation performance confirmed be due synergistic effect SV. Specifically, employment not only increased biomass but also promoted its decomposition, directly led conversion into more humic acid (HA). Under action HA, calcium phosphorus were released combined form stable compounds (e.g., Cd3(PO4)2, Cd5(PO4)3Cl, CdnCa5–n(PO4)3OH). Amazingly, excellent synergetic on improvement, content pepper fruit decreased 38.2% (6.3 SV), fresh weight Ca enhanced 28.2% 43.4% (6.7 22.8 SV, respectively). Overall, this study provided novel strategy, i.e., green manure mineral, for simultaneous remediation Cd-contaminated farmland enhancement pepper's yield quality, thus achieving "killing three birds one stone".

Machine learning and computational chemistry to improve biochar fertilizers: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(6), P. 3159 - 3244

Published: Aug. 17, 2023

Abstract Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded phosphorous is sustainable fertilizer that improves soil structure, stores carbon in soils, provides plant the long run, yet most biochars not optimal because mechanisms ruling properties poorly known. This issue can be solved by recent developments machine learning computational chemistry. Here we review phosphorus-loaded emphasis on chemistry, learning, organic acids, drawbacks classical fertilizers, production, phosphorus loading, release. Modeling techniques allow for deciphering influence individual variables biochar, employing various supervised models tailored to different types. Computational chemistry knowledge factors control binding, e.g., type compound, constituents, mineral surfaces, binding motifs, water, solution pH, redox potential. Phosphorus release from controlled coexisting anions, adsorbent dosage, initial concentration, temperature. Pyrolysis temperatures below 600 °C enhance functional group retention, while 450 increase plant-available phosphorus. Lower pH values promote release, higher hinder it. Physical modifications, such as increasing surface area pore volume, maximize adsorption capacity biochar. Furthermore, acid affects low molecular weight acids being advantageous utilization. Lastly, biochar-based 2–4 times slower than conventional fertilizers.

Ecological and sustainable implications of phosphorous-solubilizing microorganisms in soil

Deleted Journal, Journal Year: 2024, Volume and Issue: 6(2)

Published: Jan. 26, 2024

Abstract Phosphorus (P) is a macronutrient that plants need to grow. However, most of the soil’s phosphorus still insoluble, making it difficult for absorb. This creates barrier ecologically responsible farming methods and calls innovative approaches solubilization. Solublizing microorganisms improve availability phosphorous in soil. The term “phosphorus-solubilizing microorganisms” (PSMs) describes various fungi or bacteria divide into more soluble forms. It shows how PSMs interact with their processes solubilize phosphorus. Soil pH, temperature, nutrient are only few parameters affecting its activity. investigated potential increase plant absorption use, thereby boosting agricultural yield usage efficiency. use effects on environment also evaluated. By using PSMs, farmers may less chemical fertilizers contribute runoff eutrophication waterways. Furthermore, soil structure, decrease losses, cycling, all which health long-term viability systems. Phosphorus-solubilizing have enormous promise environmentally land management. Better availability, greater output, pollution, better possible outcomes PSMs. further study required determine best application strategies, formulations, choices Incorporating operations can potentially environmental sustainability resilience. article will explore addressing critical challenges, including erosion, runoff, sustainable practices, resource conservation.

Abstract Cd contamination, especially in farmland soil, can pose serious threats to human health as well ecological security. Stabilization is an important strategy for agricultural soil remediation. In this study, a Cd-resistant strain ( Cupriavidus B-7) was isolated and loaded onto cow manure (CDB), rice straw (RSB) pine wood biochar (PB) investigate its effects on stabilization by 60-day pot experiment. Results indicated that the B-7-loaded (labelled CDBB, PBB RSBB) reduced CaCl 2 -extractable 43.06–59.78%, which significantly superior individual applications of B-7 biochar. Likewise, physicochemical properties, urease, catalase phosphatase activities were improved, indicating improved health. Consequently, dry weights pakchoi’s shoot root increased 938.9–1230.9% 149.1–281.2%, respectively, applying RSBB. Meanwhile, accumulation pakchoi shoots decreased 38.06–50.75%. Notably, RSBB exhibited optimal performance growth promotion alleviation. The structural equation model synergistic effect between B-7.
