Regional differences affect soil fertility

Description
Biochar = biomass is reduced to a black, carbon-rich, charcoal-like residue
Can hold onto plant nutrients thus enhancing fertility of soil
Also effective at absorbing and holding heavy metals
May act as a long-term reservoir for carbon

Characteristics of soil and soil profiles vary
Compare tropical rain forests and temperate grasslands
In rain forests, most nutrients are tied up in plant tissue
Much less productive than soil of temperate grasslands
More leaching in rainforest
Main differences is in temperature and rainfall
