Effect of surface and porosity of biochar on water holding capacity aiming indirectly at preservation of the Amazon biome

Abstract As part of efforts to reduce pressure on the Amazon and other biomes, one approach considered by Brazilian authorities and scientists is more intensive use of the soils of the interior of the northeast of the country, which are generally sandy, with low contents of organic matter and low wa...
