WebFeb 24, 2024 · Abstract. Oxisols are extremely weathered soils that are predominantly found in intertropical regions throughout the globe (from the French word "oxide,"). These soils … WebGenerally lacking in development, they are not extensively weathered, forming in deposits from geologically recent events. Usually of high natural fertility, they tend to accumulate organic matter readily and are of a ‘light’ nature (low bulk density) that is easily tilled. These soils generally have a high productivity potential.
