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. WebJul 9, 2024 · This eutrophic nature is attributed to the protecting role of micro-aggregates in ferric red Latosols, which retard baseleaching from the inner aggregate. At the other extreme, some Brazilian Latosols are acric and positively-charged in sub-surface horizons, as revealed by the relationship pH KCl > pH H 2 O. These acric Latosols are the result ...

WebBecause of the rapid uptake of nutrients by the plants and the leaching that occurs, latosols are quite infertile. Chemical weathering of the parent rock is very strong in such a hot, wet climate. As a result, latosols lack nutrients and only iron and aluminium remain. In many places latosols are so rich in aluminium that they are termed ... WebContaminants may also be absorbed through the skin. Creosote is a common material used to preserve wood in the United States. This complex mixture of chemicals can leach out of treated wood and contaminate the soil. If creosote-contaminated soils are touched, then over time the skin may blister, peel or severely redden. 4.
