'Jan Hajzler' 'Leona Kubikova' 'Vojtech Enev' 'Jianbin Zhou' 'HuanHuan Ma'] Biochar is a versatile carbon-rich organic material originating from pyrolyzed biomass residues that possess the potential to stabilize organic carbon in the soil, improve soil fertility and water retention, and enhance plant growth. For the…

As multibillion-dollar projects intended to sequester carbon dioxide (CO2) in deep geologic storage continue to seek financial support, the fertile black soils in the Amazon basin suggest a cheaper, lower-tech route toward the same destination. Scattered patches of dark, charcoal-rich soil known as terra preta…

A number of processes for post-production treatment of “raw” biochars, including leaching, aeration, grinding or sieving to reduce particle size, and chemical or steam activation, have been suggested as means to enhance biochar effectiveness in agriculture, forestry, and environmental restoration. Here, I review…

Biochar, produced via biomass pyrolysis, is an emerging method for carbon removal in agriculture. However, its uncertain environmental outcomes hinder large-scale adoption. We address this using physics-informed machine learning (ML) to integrate kinetics-based pyrolysis modeling and global datasets of field…

Biochars are porous charcoal-like materials that can enhance soil health and plant growth, but its use has not been adequately evaluated in woody cropping systems. We set up an experimental Christmas tree plantation on a Marlette series soil amended with two types of biochar and conducted two studies on the impacts of…

Soil fertility decline represents a major constraint to crop productivity in sub-Saharan Africa. Many studies have shown that addition of biochar or compost can effectively improve soil quality. Biochar produced from crop residues are often N-poor but rich in stable C while poultry manure composts, which is often rich…

Biochars are an exciting class of environmental materials with a wide range of applications, including carbon storage and sequestration, soil enhancement, and pollution remediation. However, the limited knowledge of their molecular structures and compositions and the lack of comprehensive understanding of the…

Biochar amendment can alter soil properties, for instance, the ability to adsorb and degrade different chemicals. However, ageing of the biochar, due to processes occurring in the soil over time, can influence such biochar-mediated effects. This study examined how biochar affected adsorption and degradation of two…

The purpose of this study is to measure the benefits and costs of using biochar, a carbon sequestration technology output, to reduce the B.C Wine Industry's carbon emissions. In this study, carbon sequestration refers to the process of capturing and storing atmospheric carbon dioxide in the soil. Opportunities for…

'Yibo Ma'] Toxic organic pollutants in wastewater have seriously damaged human health and ecosystems. Photocatalytic degradation is a potential and efficient tactic for wastewater treatment. Among the entire carbon family, biochar has been developed for the adsorption of pollutants due to its large specific surface…

Biochar amendment has multifaceted benefits on the soil-plant system; yet the underlying mechanisms remain poorly understood. Integrating microfluidics and multi-omics and using wheat as a model plant, we demonstrate that biochar induces differential root exudation which rewires the rhizosphere microbiome and its…

Biochars are black carbonaceous solids produced through biomass pyrolysis under conditions of little or no oxygen. Whilst their properties are well studied, and their applications numerous, the underlying molecular structures within biochars still need to be defined. This raises a substantial barrier to the molecular…

The use of biochar in combination with mineral or biological amendments in order to improve its influence on soil-plant properties has received growing attention. The changes of N, C and P content in Lactuca sativa var. capitata aboveground plant biomass and soil after the addition of beech wood biochar combined with…

In this study, a greenhouse pot experiment with maize (Zea mays L.) was conducted using treatments consisting of a control (CK), inorganic fertilizer of NPK (INF), and 1% and 3% (wt/wt) of olive mill solid waste (OMSW)-derived biochar (BC) at various pyrolytic temperatures (300–700 °C). The goal was to investigate…

Most calcareous soils have relatively low levels of organic matter. To address this issue and improve the qualitative properties of calcareous soils, soils can be treated with mycorrhizal fungi and/or exogenous organic material such as biochar or compost derived from tree pruning waste. To evaluate the effect of…

'Anssi Källi' 'Kimmo Rasa'] Abstract Pore space characteristics of biochars may vary depending on the used raw material and processing technology. Pore structure has significant effects on the water retention properties of biochar amended soils. In this work, several biochars were characterized with three-dimensional…

The effectivity of biochar as soil amendment is depending by its physical and chemical characteristics that are related to the type and the features of the thermal production process, such as peak temperature, heating rate, holding time, as well as from the used feedstocks. The textural characteristics of biochar in…

Pyrene is a polycyclic aromatic hydrocarbon (PAH) organic compound. Here we consider its Raman spectroscopy, and how it is revealing, when used to create nanograins (Gavilan et al., 2022), a spectrum which is like that we can observe when biochar is investigated. Besides the approach by Gavilan and coworkers, the…

An emerging strategy to remove CO2 from the atmosphere and compensate for the greenhouse-gas emissions of cement and concrete is based on incorporating biochar into concrete. With this approach, concrete can be turned into a functional carbon sink (C-sink). Until now, biochar has been used without modification to…
