Tropical Rainforest Characteristics Soil

A thin layer of fertile soil is found at the surface where the dead leaves decompose. Millions of years of weathering have washed most of the nutrients out of the soil. Ground level - contains less vegetation due to the dark damp conditions a thick layer of decomposing leavesand the.

Only about 20 of tropical soils are suitable for agriculture.

Tropical rainforest characteristics soil. The recurring features of rainforests are basically the following. Characteristics of the tropical forest. Due to the high humid temperatures in tropical rainforests it speeds up and has a rapid fast growing.

Climatic conditions in tropical rainforests have an average of 27 degrees annually and an average rainfall of approximately 200cm with a permanently high humidity. Despite the amount of vegetation in the rainforest the soil contains less organic matter than that of temperate forests because the warm humid conditions encourage faster decay and recycling of nutrients back into living forest. Tropical rainforests are characterized by rainfall and evergreen species.

Some tropical trees have developed huge buttress roots to absorb nutrients from the soil. Most of the soil is not very fertile. There are 4 layers of soil in the tropical rain forest.

In the soil in a tropical rainforest there is usually a low level of minerals nutrients and organic matter present. 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. Due to heavy rainfall.

It is red in colour because it is rich in iron. Characteristics of the tropical forest. 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.

Because of the lack of seasonal differences due to the geographical location of the forests and the high humidity level the vegetation is luxuriant here. Some soils are also exposed. When the soil is acidic there is little difference and therefore little absorption of nutrients from the soil.
