WebAn important factor that can affect the degree of leaching is how much water a soil can hold. For example, by their nature sandy soils cannot hold as much water as clay soils. This means that leaching of nitrates will take place much more easily in a sandy soil compared to a clay soil. Often, leaching is not a significant factor in heavy clay ... WebFormation of Latosols. Formed by the process of leaching. The soluble bases, sesquioxides and silica are removed from the upper layers /A-horizon and deposited in the lower AHorizon. This occurs mainly in the savanna and equatorial areas that receive heavy rainfall. / Rainwater mixes with carbondoxide to form a weak carbonic acid that dissolves ...

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 ... WebThis spike in oxygen usage can sharply lower dissolved oxygen levels in the water and may lead to death by anoxia —lack of oxygen—for other aquatic organisms, such as shellfish and finfish. Regions of lakes and oceans that are depleted of oxygen due to a nutrient influx are called dead zones. highfield maths level 1 past papers
