Biochar is a carbon-rich material that is distinct from charcoal and other similar materials dueto its use as a soil conditioner to improve soil quality. One factor limiting understanding andvalidation of biochar as a soil conditioner and carbon sink is the lack of long-duration studies inthe field. Such studies are essential, since biochar can be produced from a wide variety of rawmaterials and thermic processes, leading to very diverse products. Most studies are done ingreenhouses; due to cost

According to data from the IPCC (2007), agriculture is one of the economic sectors accountingfor the most greenhouse gas emissions. Conventional nitrogen-based fertilizers are mostcommonly used in agriculture, and nitrogen is lost very quickly as their componentsdecompose. The generally low efficacy of nitrogen-based fertilizers not only leads to technicaland economic losses, but also contributes to higher concentrations of greenhouse gases in theatmosphere by releasing nitrous oxide (N 2 O), a

Amazonian dark earths are highly rich soils that resist degradation. They have an extraordinarycapacity to sequester carbon and are known to augment agricultural production. Because ofthese characteristics, these dark earths have been proposed as a model for sustainableagriculture. But most attempts to recreate them have been unsuccessful, with little research ordata on the role of soil biota in the productivity and resilience of this ecosystem. An initialassay in a greenhouse simulated dark ear
