An Introduction to Biochars and Their Uses in Agriculture

CharcoalBiochar, also known as black carbon, is a product derived from organic materials rich in carbon and is found in soils in very stable solid forms, often as deposits. In recent years, considerable research has focused on biochar, its nature, and its properties to explore its potential benefits and negative impacts, particularly for applying to agricultural fields as amendments. This publication provides a general description of biochar, as well as technical details, benefits, and disadvantages of biochar for agricultural and environmental uses. This 4-page fact sheet was written by Rao Mylavarapu, Vimala Nair, and Kelly Morgan, and published by the UF Department of Soil and Water Science, August 2013.

ENH1086/EP351 Mycorrhizae: Implications for Environmental Remediation and Resource Conservation

ENH-1068, a 5-page fact sheet by J. Sharma, A.V. Ogram, and A. Al-Agely, describes the symbiotic relationships between plant roots and fungi and how the resulting rhizosphere activity can lead to transformation and removal of polluting compounds from the soil, reduce the need for fertilizer in commercial nurseries, and improve soil structure and health. Includes references. Published by the UF Department of Environmental Horticulture, November 2007.
