Mostrainforestsoilsarethinandpoorbecausetheylackmineralsandbecausetheheatandheavyrainfalldestroymostorganicmatterinthesoilswithinfouryearsofitreachingtheforestfloor.Thismeanstopsoilcontainsfewoftheingredientsneededforlong-termsuccessfulfarming.
ButBrunoGlaser,asoilscientistoftheUniversityofBayreuth,hasstudiedunexpectedpatchesoffertilesoilsinthecentralAmazon.Thesesoilscontainlotsoforganicmatter.
Glaserhasshownthatmostofthisfertileorganicmattercomesfrom“blackcarbon”—theorganicparticlesfromcampfiresandcharred（烧成炭的）woodleftoverfromthousandsofyearsofslash-and-burnfarming.”Thesoils,knownasTerraPreta,containedupto70timesmoreblackcarbonthanthesurroundingsoil,”saysGlaser.
Unburntvegetationrotsquickly,butblackcarbonpersistsinthesoilformanycenturies.RadiocarbondatingshowsthatthecharredwoodinTerraPretasoilsistypicallymorethan1,000yearsold.
“Slash-and-burnfarmingcanbegoodforsoilsprovideditdoesn’tcompletelyburnallthevegetation,andleavesbehindcharredwood,”saysGlaser.“Itcanbebetterthanmanure（粪肥）.”Burningtheforestjustoncecanleavebehindenoughblackcarbontokeepthesoilfertileforthousandsofyears.Andrainforestseasilyregrowaftersmall-scaleclearing.Contrarytotheconventionalviewthathumanactivitiesdamagetheenvironment,Glasersays:
