   Govaerts et al., 2005
Mitigacion
● Gases traces = CO2 + CH4 + N2O
● No se encontró diferencia en las emisiones del
  suelo 242 kg CO2-C ha-1 y-1 máximo
● Contenido de C orgánico en el suelo (0-60 cm):
  Agricultura de conservación 40,000 kg C ha-1 >
  que convencional
● Agricultura de conservación secuestró 2,000 kg
  C ha-1 y-1
● Agricultura de conservación redujo emisiones de
  las operaciones con 74 kg C ha-1
Mitigacion
● Net Potencial de Calentamiento de la Tierra
  Agricultura de conservación neutral
   40 kg CO2-C ha-1 y-1
  Convencional es un emisor
   2,000 kg CO2-C ha-1 y-1
Literature review

 ● Govaerts et al., submitted
 ● West and Post (2002), Jarecki and Lal (2003),
   VandenBygaart et al. (2003), Blanco-Canqui
   and Lal (2008) + Literature search (Web of
   Science)
 ● Only >5y and minimum 30cm
 ● Very little research in Africa, Central- Latin-
   America, Asia
Literature review

 ● Conventional till  Zero tillage
  8/62 cases C stock decreased
  21/62 cases C stock not significant different
  33/62 case C stock increased
 ● Increased rotation
  22/55 cases C stock decreased
  5/55 cases C stock not significant different
  28/55 cases C stock increased
