Biochar from date palm and conocarpus waste for improvement of soil quality and biomass production

Biochar is a solid fine-grained material obtained from the carbonization of biomass under oxygen-limited conditions.‎ Biochar may be applied directly to soils to improve soil functions and to reduce emissions from biomass.‎ Due to its stability, biochar has an important role in carbon sequestration (the process of capturing CO۲ before it escapes into the atmosphere).‎ This 2,000 year-old practice converts agricultural waste into a soil enhancer that can hold carbon, boost food security, increase soil biodiversity, and discourage deforestation.‎ The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water.‎ Biochar is found in soils around the world as a result of vegetation fires and historic soil management practices.‎ Intensive study of biochar-rich dark earths in the Amazon (terra preta), has led to a wider appreciation of the unique properties of biochar as a soil enhancer.‎
