Biochar as Soil Amendment: Impact on Soil Properties and Sustainable Resource Management

The role of biochar in improving soil fertility is increasingly being recognized and is leading to recommendations of biochar amendment of degraded soils. In addition biochars offer a sustainable tool for managing organic wastes and to produce added-value products. The benefits of biochar use in agriculture and forestry can span enhanced plant productivity an increase in soil C stocks and a reduction of nutrient losses from soil and non-CO2 greenhouse gas emissions. Nevertheless biochar composition and properties and therefore its performance as a soil amendment are highly dependent on the feedstock and pyrolysis conditions. In addition due to its characteristics such as high porosity water retention and adsorption capacity there are other applications for biochar that still need to be properly tested. Thus the 16 original articles contained in this book which were selected and evaluated for this Special Issue provide a comprehensive overview of the biological chemicophysical biochemical and environmental aspects of the application of biochar as soil amendment. Specifically they address the applicability of biochar for nursery growth its effects on the productivity of various food crops under contrasting conditions biochar capacity for pesticide retention assessment of greenhouse gas emissions and soil carbon dynamics. I would like to thank the contributors reviewers and the support of the Agronomy editorial staff whose professionalism and dedication have made this issue possible.
