Red soil is a type of soil that typically develops in warm, temperate, and humid climates and comprise approximately 13% of Earth's soils. It contains thin organic and organic-mineral layers of highly leached soil resting on a red layer of alluvium. Red soils contain large amounts of clay and are generally derived from the weathering of ancient crystalline and metamorphic rock. They are named after their rich red color, which can vary from reddish brown to reddish yellow as a result of their high iron content. Red soil can be good or poor growing soil depending on how it is managed. It is usually low in nutrients and humus and can be difficult to cultivate due to its low water holding capacity; however, the fertility of these soils can be optimized with liming and other farming techniques.

- Un sol rouge (terre rouge) est le nom générique d'un type de sol qui se développe généralement sous un climat chaud ou tempéré et humide. Environ 13 % des sols de la Terre sont des sols rouges. Il ne contient que de fines couches organiques et organo-minérales en raison d'un fort ou long lessivage. Cette couche (horizon superficiel) repose sur une couche rouge d'alluvions. Ils sont riches en argile et dérivent généralement de l'altération d'anciennes roches cristallines et métamorphiques. Leur couleur rouge, brun-rougeâtre à jaune-rougeâtre est due à une forte teneur en fer. (fr)

| - Un sol rouge (terre rouge) est le nom générique d'un type de sol qui se développe généralement sous un climat chaud ou tempéré et humide. Environ 13 % des sols de la Terre sont des sols rouges. Il ne contient que de fines couches organiques et organo-minérales en raison d'un fort ou long lessivage. Cette couche (horizon superficiel) repose sur une couche rouge d'alluvions. Ils sont riches en argile et dérivent généralement de l'altération d'anciennes roches cristallines et métamorphiques. Leur couleur rouge, brun-rougeâtre à jaune-rougeâtre est due à une forte teneur en fer. C'est un bon ou mauvais substrat de croissance pour les cultures, selon la façon dont il est géré. Souvent acide, pauvre en nutriments et en humus et vulnérable à l'érosion, il peut être difficile à cultiver en raison de sa faible capacité de rétention d'eau. Sa fertilité peut être optimisée avec un chaulage, l'apport de matière organique, et d'autres techniques agricoles. Dans des pays comme la Chine, l'Inde et la Grèce où il y a de grandes quantités de terre rouge, la compréhension des propriétés du sol est cruciale pour une agriculture durable et soutenable. Les propriétés du sol rouge peuvent varier d'une région à l'autre et peuvent nécessiter des pratiques de gestion différentes. (fr)

It is usually low in nutrients and humus and can be difficult to cultivate due to its low water holding capacity; however, the fertility of these soils can be optimized with liming and other farming techniques. Red soils are an important resource because they make up such a large portion of farmland on the earth. In countries such as China, India, and Greece where there are large amounts of red soil, understanding the soil's properties are crucial to successful agriculture. Red soil properties can vary across regions and may require different management practices to achieve the best results. (en)
