CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Relative importance of soil organic matter, soil litter and litter fall in the tropics

Exporter la citation

Organic matter in soils (SOM) is represented by plant and animal residues in various stages of decomposition, containing typically 58% of Carbon. Carbon content of soils is considered as a major indicator of soil quality, including water retention capacity. However, only organic particles passing through the 2 mm sieve are considered. Moreover, soil litter is generally given less importance in the interpretation of soil quality. Under tropical forest conditions it is not rare to find soils with less than 1% carbon although soil litter is undergoing an active humification process, continuously supplied with litter fall. Several coefficients taking both annual litter fall and soil litter into account, provide more dynamic interpretation tools of soil quality under tropical conditions as illustrated with several examples from Latin-America and Africa.
