Does Biochar Improve All Soil Ecosystem Services?, Humberto Blanco-Canqui
Does Biochar Improve All Soil Ecosystem Services?, Humberto Blanco-Canqui
Department of Agronomy and Horticulture: Faculty Publications
Biochar is considered to sequester C and deliver other soil ecosystem services, but an overview that synthesizes the current knowledge of biochar implications on all essential soil ecosystem services is difficult to find in the ample biochar literature. Most previous research and review articles on this topic focused on a single ecosystem service and did not integrate all essential soil ecosystem services. This overview paper (1) synthesizes the impacts of biochar on water and wind erosion, C sequestration, soil water, nutrient leaching, soil fertility, crop yields, and other soil ecosystem services based on published literature and (2) highlights remaining research …

Applying biochar to agricultural soils has been proposed as a means of sequester-ing carbon (C) while simultaneously enhancing soil health and agricultural sustain-ability. However, our understanding of the long-term effects of biochar and annual versus perennial cropping systems and their interactions on soil properties under field conditions is limited. We quantified changes in soil C concentration and stocks, and other soil properties 6 years after biochar applications to corn (Zea mays L.) and dedicated bioenergy crops on a Midwestern US soil. Treatments were as fol-lows: no-till continuous corn, Liberty switchgrass (Panicum virgatum L.), and low-diversity prairie grasses, 45% big bluestem …
Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli
Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli

Intensive agriculture practices often results in decomposition of organic matter, thus causing soil CO2 emissions. Agro-ecological service crop could be profitably cultivated to improve soil characteristics and reduce CO2 emissions under Mediterranean environment. Two-year field trials were conducted in central Italy. The treatments were three agro-ecological service crops (hairy vetch, oat, and oilseed rape) and a no-service cover. Plant development, soil characteristics, and CO2 emissions were measured. Oat and oilseed rape showed a rapid growth, while hairy vetch started to grow rapidly only after the cold period. Soil CO2 emissions trend was similar among the agro-ecological …
