  author={Bruno Glaser and Johannes Lehmann and Wolfgang Zech},

Abstract. Rapid turnover of organic matter leads to a low efficiency of organic fertilizers applied to increase and sequester C in soils of the humid tropics. Charcoal was reported to be responsible for high soil organic matter contents and soil fertility of anthropogenic soils (Terra Preta) found in central Amazonia. Therefore, we reviewed the available information about the physical and chemical properties of charcoal as affected by different combustion procedures, and the effects of its…

Physical and Chemical Properties of Pinus ponderosa Charcoal: Implications for Soil Modification
Abstract Charcoal is the result of incomplete combustion of plant material. It is common as residue from wild and prescribed fires in many soil surface horizons, including those of the extensive
Use of pyrolysis char as an amendment in soils of the Southeastern United States
Soils in the southeastern United States are characterized by low natural fertility, low soil organic carbon (SOC), and low activity clays. Climate and a history of poor soil management in the region
Effects of biochar on soil fertility and crop productivity in arid regions: a review
Biochar, carbon-rich materials produced during the thermochemical processing of biomass, are receiving increased attention given their potential value as soil amendments. Biochar are formed through
Ameliorating chemical properties of acid soils with biochar-A review
Amelioration of acid soil is a challenging task for the scientific community to mitigate the rising concentration of H and Al ion. Biochar used as a liming material in acid soil due to its high soil
Effects of charcoal production on soil biodiversity and soil physical and chemical properties in Togo, West Africa.
In Togo, traditional energy sources including charcoal represent 80% out of total household energy requirements. The techniques of charcoal production in earth kiln are quite common. During
A review of biochar and its use and function in soil
Abstract Agricultural activities and soils release greenhouse gases, and additional emissions occur in the conversion of land from other uses. Unlike natural lands, active management offers the
Role of charcoal addition on infiltration processes and soil water content characteristics of a sandy loam soil
Terra preta (TP) is a soil amendment which is enriched with powdered charcoal, with nutrient sources from organic residues, and that constitutes a resource to improve soils for sustainable land use
Co-Application of Charcoal and Wood Ash to Improve Potassium Availability in Tropical Mineral Acid Soils
Potassium (K) is a macronutrient required by plants for energy production, enzyme activation, formation of cell wall, production of protein, and photosynthesis. However, K in the soil solution is
Biochar: Agronomic and environmental potential in Brazilian savannah soils
A B ST R A C T Due to the high activity of microorganisms, the loss of soil organic matter is high in tropical regions. This loss becomes even greater if the soil is managed improperly or when there
Manioc peel and charcoal: a potential organic amendment for sustainable soil fertility in the tropics
The application of a mixture of manioc peel and charcoal, by improving crop production and soil fertility and enhancing earthworm activity, could be a potentially efficient organic manure for legume production in tropical areas where maniOC is cultivated under slash-and-burn shifting agriculture.


Slash-and-char : a feasible alternative for soil fertility management in the Central Amazon ?
The application of charcoal to nutrient-poor upland soils of the central Amazon was tested in lysimeter studies in comparison to unamended control to evaluate the effects of charcoal on plant
Potential of Pyrolyzed Organic Matter in Soil Amelioration
To secure food supply for the increasing population there is an urgent need to intensify the agricultural production especially in less developed countries of the tropics. There, soils are frequently
Factors controlling humification and mineralization of soil organic matter in the tropics
Abstract The first part of this review focuses on the chemical composition and morphological features that characterize primary and secondary organic resources for humification. The chemical pathways
Charred organic carbon in German chernozemic soils
Summary Burning vegetation produces partly charred plant material which subsequently could contribute to the highly refractory proportion of soil organic matter. The presence of charred organic
The role of soil organic matter in sustaining soil fertility
MANY tropical soils are poor in inorganic nutrients and rely on the recycling of nutrients from soil organic matter to maintain fertility. In undisturbed rainforests such nutrients are recycled via
