WebMar 13, 2024 · This process is called leaching. Under normal circumstances, minor levels of leaching occur with typical rainfall, and the breakdown of organic materials on the surface resupplies the soil. In the case of excessive rainfall or irrigation, the effects of soil leaching can be more dramatic. WebChemical weathering reactions (especially the formation of clay minerals) and biochemical reactions proceed fastest under warm conditions, and plant growth is enhanced in warm climates. Too much water (e.g., in rainforests) can lead to the leaching of important chemical nutrients and hence to acidic soils.

Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. They are typically classified as oxisols (USDA soil taxonomy) or ferralsols (World Reference Base for Soil Resources). It is largely correct to say that latosols are tropical soils, but the reverse is not true because there are many soils in the tropics that are not latosolic. Latosols are red or yellowish-red in colour throughout and they do … Webgeneous class. In particular, the agricultural potential of latosols ranges from high to very low. The main types of latosols are ferruginous soils, leached ferrallitic soils, weathered ferrallitic soils and ferrisols. The properties of each of these are described and illustrated and their agricultural potential compared. Some common misconceptions biometric picture for german passport
