Tropical Rainforest Characteristics Soil

Characteristics of the tropical forest.

Tropical rainforest characteristics soil. The soils of tropical rainforests are characterized by rapid recycling of fallen leaves and other organic matter due to the large biomass of the rainforest. Soil in the tropical rainforest is particularly very poor because the soil is more than 100 million years old. In the Amazon tropical rainforest the soil are mostly several metres deep.

The second level which in also semi small is called the Topsoil this layer of soil is semi poor in nutrients because of plants growing above them taking in all the nutrients as it is produced. Transpiration from the evergreen trees results. Due to heavy rainfall.

Climatic conditions in tropical rainforests have an average of 27 degrees annually and an average rainfall of approximately 200cm with a permanently high humidity. During the 100 million years rain wash the minerals of the soil out which make the soil acidic and poor in nutrients. The recurring features of rainforests are basically the following.

Ground level - contains less vegetation due to the dark damp conditions a thick layer of decomposing leavesand the. The forests are located in the tropical wet humid regions with an average annual rainfall of around 200-225 cm. It is red in colour because it is rich in iron.

The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. Many of these soils are oxisols and ultisols. The tropical rainforest is often in the news for various reasons.

The tropical rainforest biome has four main characteristics. Runoff and soil erosion characteristics were investigated in three small catchments a virgin forest catchment C1 a 10-year-old line plantation catchment C2 and a 1-year-old line plantation catchment C3. Some soils are also exposed.
