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.

The fertility capability of soil classification system: interpretation, applicability and modification

Exporter la citation

This paper summarizes the first five years of testing and evaluation of the Fertility Capability Soil Classification System (FCC) and presents an improved version, examples of interpretation and its applicability. FCC is a technical system for grouping soils according to the kinds of problems they present for agronomic management of their chemical and physical properties. It emphasizes quantifiable topsoil parameters as well as subsoil properties directly relevant to plant growth. FCC-classes indicate the main fertility-related soil constraints, which can be interpreted in relation to specific farming systems or land utilization types. Since its publication in 1975, the FCC has been tested, evaluated and put to use in various countries. As a result, the definitions of several modifiers have been changed and additional modifiers have been introduced. Soil maps can be interpreted and redrawn as FCC-units when the necessary data are available. Portions of the FAO/Unesco (1971, 1974, 1977) Soil Maps of the World have been converted to FCC-units with minor difficulties. The system is directly applicable to FAO's (1976) Land Evaluation Guidelines.
