Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated during the composting process. As a result, the moisture content of gasification coke increased from 0… 

Effects of biochar amendments on soil microbial biomass and activity.

This study shows that biochars produced at 700°C, regardless of feedstock source, do not enhance soil microbial biomass or activity, and indicates that production of biochar at this high temperature eliminated potential substrates.

Effect of biochar amendment on compost organic matter composition following aerobic composting of manure.

Physio-Chemical Characterization of Biochar, Compost and Co-Composted Biochar Derived from Green Waste

Organic wastes are naturally biodegradable, but they contribute to environmental pollution and management issues. Composting and pyrolysis are widely used technologies for recycling these wastes into

Greenhouse gas production in mixtures of soil with composted and noncomposted biochars is governed by char-associated organic compounds.

Changes of organic matter associated with two biochars after 175 d of composting and the resulting effects on GHG emissions during a 150-d incubation period are examined.

Straw biochar hastens organic matter degradation and produces nutrient-rich compost.

Role of biochar on composting of organic wastes and remediation of contaminated soils—a review

An overview on the impact of biochar on the chemical characteristics (greenhouse gas emissions, nitrogen loss, decomposition and humification of organic matter) and microbial community structure during composting of organic wastes and related mechanisms is provided.

Effect of biochar on leaching of organic carbon, nitrogen, and phosphorus from compost in bioretention systems.

Plant growth improvement mediated by nitrate capture in co-composted biochar

It is demonstrated that co-composting considerably promoted biochars’ positive effects, largely by nitrate (nutrient) capture and delivery, and hypothesize that surface ageing plus non-conventional ion-water bonding in micro- and nano-pores promoted nitrate capture in biochar particles.



Characterisation and evaluation of biochars for their application as a soil amendment

Biochar properties can be significantly influenced by feedstock source and pyrolysis conditions; this warrants detailed characterisation of biochars for their application to improve soil fertility

Sorption of copper (II) and sulphate to different biochars before and after composting with farmyard manure

Biochar application has been suggested for reducing toxic levels of metals in contaminated soils and enhancing nutrient retention in agro‐ecosystems. We studied sorption of copper (Cu(II)) and

A glasshouse study on the interaction of low mineral ash biochar with nitrogen in a sandy soil

The effect of a low mineral ash biochar on biomass production and nitrogen (N) uptake into plants was tested with wheat and radish in a Yellow Earth used for commercial vegetable production. The

Influence of Pecan Biochar on Physical Properties of a Norfolk Loamy Sand

Because the southeastern US Coastal Plain has high temperatures and abundant rainfall, its sandy soils have poor physical characteristics and low carbon (C) contents. To increase soil C, we added

Because biochar lability was found to be strongly controlled by the relative amount of a more aliphatic and volatile component, measurements of volatile weight content may be a convenient predictor of biochar C longevity.

Effect of Charcoal Quantity on Microbial Biomass and Activity in Temperate Soils

Wildfi re-produced charcoal is a common component of soils, affecting a range of important abiotic and biotic soil processes. Our ability to predict the effects of charcoal addition to soil is

Bio-char Sequestration in Terrestrial Ecosystems – A Review

The application of bio-char (charcoal or biomass-derived black carbon (C)) to soil is proposed as a novel approach to establish a significant, long-term, sink for atmospheric carbon dioxide in
