Biochar, a form of pyrogenic carbon, can contribute to agricultural and environmental sustainability by increasing soil reactivity. In soils, biochar could change its role over time through alterations in surface chemistry. However, mechanistic understanding the aging process ionic nutrient adsorption supply remain unclear. Here, we aged wood (550 °C) chemical oxidation with 5-15% H2O2 investigated changes chemistry behavior ammonium phosphate. Oxidation changed functionality introduction...
Fulvic and humic acids have a large variability in binding to metal (hydr) oxide surfaces interact differently with oxyanions, as examined here experimentally. Pyrogenic acid has been included our study since it will be released the environment case of large-scale application biochar, potentially creating Darks Earths or Terra Preta soils. A surface complexation approach developed that aims describe competitive behavior natural organic matter (NOM) soil well model systems. Modeling points...
Abstract Biochar is a pyrolysed biomass and largely consists of pyrogenic carbon (C), which takes much longer to decompose compared the it made from. When applied soil, could increase agricultural productivity through nutrient retention changing soil properties. The biochar‐mediated capacity depends on biochar properties, change with time, Here, we examined effects wood (20 t ha −1 ), that has aged (21 months) in grassland field, gross nitrogen (N) mineralization ( GNM ) 15 N recovery using...
Biochar is a carbonaceous material produced from the slow/fast pyrolysis of biomass under limited or no supply oxygen. It has diverse uses climate change mitigation to contaminant remediation environment. However, biochar's role in bringing these changes depends on its physicochemical properties, suggesting use function-specific biochar for achieving specific target. This review summarizes basic properties and how they are affected by different modification strategies. also looks at heavy...
Although its mechanism of action, particularly under wetland condition, is not clearly understood, vermicompost, a good source humus and plant nutrients, has been used as organic manure in many parts the world order to increase crop production. Here, an anaerobic incubation study field were conducted observe nutrient release pattern from vermicompost influence on performance uptake rice. Two contrasting soils, viz. highly weathered terrace soil very young floodplain soil, subjected...
Climate change contributes to a rise in salinity levels the coastal regions of Bangladesh, notably impacting agricultural productivity. Therefore, crop-level adaptation strategies against are crucial increase In this study, our objective is explore farm-level climate change-induced south-central area considering farmers' perception and ingress as well their strategies. Subsequently, we compare findings with climatic data acquired from secondary sources. The study was partitioned into three...
Soil acidity is a major problem of agriculture in many parts the world. causes multiple problems such as nutrient deficiency, elemental toxicity and adverse effects on biological characteristics soil, resulting decreased crop yields productivity. Although number conventional strategies including liming use organic inorganic fertilizers are suggested for managing soil but cost-effective sustainable amendments not available to address this problem. Currently, there increasing interest using...
Salinity varies with location and time of the year. It can significantly impact crop production. The level negative impacts depends on salt concentration its occurrence, which, however, has not been studied for many crops, especially rice grown in coastal area Bangladesh. Our study explored spatio-temporal fluctuations soil water salinity boro production south-central coast Here, we simulated from November 2020 to May 2021 fourteen locations classes using SWAP-WOFOST model. model was...
Maize is an important cereal in many developed and developing countries of the world. One primary challenges for maize cultivation soil acidity. Acidic a major constrain achieving food security requiring sustainable solutions. Biochar, pyrogenic carbon-rich material, carries reactive surfaces (i.e., high surface area variable charges). Therefore, it facilitates nutrient retention gradual release to plants, thereby supporting crop growth. However, combine effects functionalized biochar with...
The coastal regions of Bangladesh host a rich diversity Aman rice landraces, which are crucial for local agriculture but highly vulnerable to natural disasters like cyclones and floods. Specifically, landraces often experience flooding during grain filling maturation stages, sprouts in the field lead severe loss yield. Seed dormancy, delays germination, is key trait escaping sprouting harvesting. However, there lack information on genetic variability existing grown area Bangladesh. This...
Salinity in soils and water of coastal tracts Bangladesh, one the major challenges for agriculture, varies significantly due to multiple stressors, including consequences rapid changes climate pattern. However, their dynamics has not been studied detail accentuating its importance management agriculture. Here, we examined such along zones - defined by spatial proximity from seafront towards inland south-central coast Bangladesh. Samples soil were collected at single-month intervals between...
Biochar, an ecologically friendly soil amendment, is suggested for large-scale field application its multiple potential benefits, including carbon sequestration, crop yield improvement, and the abatement of greenhouse gas emissions. However, it unknown how effective in changing properties associated improvement when biochar co-applied with lime acidic soil. Here, we examined effects two different biochars, i.e., rice husk (RHB) oil palm empty fruit bunches (EFBB), on nutrient availability,...
