Answer Details
An important characteristic of the B-horizon in tropical ferruginous soils is the accumulation of oxides. Ferruginous soils are those that are rich in iron, and they are common in tropical regions with a distinct wet and dry season. In these soils, the B-horizon is the layer of soil that lies immediately below the A-horizon, which is the top layer of soil where most of the organic matter is found. The B-horizon is usually less fertile than the A-horizon, and in tropical ferruginous soils, it is characterized by a high concentration of iron oxides, which gives the soil a reddish-brown color. The accumulation of these oxides in the B-horizon is often the result of leaching or eluviation of oxides from the A-horizon due to heavy rainfall, leaving behind the iron oxides in the B-horizon. This accumulation of oxides in the B-horizon can also affect the soil's pH and nutrient availability.
