Tropical Rainforest Characteristics Soil

The last layer of soil is made up of rock and this makes up the majority of the soils content almost half.

Tropical rainforest characteristics soil. High animal and vegetal biodiversity. The soil is highly acidic. Very high annual rainfall high average temperatures nutrient-poor soil and high levels of biodiversity species richness.

When the soil is acidic there is little difference and therefore little absorption of nutrients from the soil. Due to the high humid temperatures in tropical rainforests it speeds up and has a rapid fast growing. This high rate of decomposition is the result of phosphorus levels in the soils precipitation high temperatures and the extensive microorganism communities.

Soils remained slightly alkaline pH 7475 with higher concentrations of calcium magnesium and potassium than in acid soils of older rainforests. The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. Ground level - contains less vegetation due to the dark damp conditions a thick layer of decomposing leavesand the.

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. During the 100 million years rain wash the minerals of the soil out which make the soil acidic and poor in nutrients. Soil - Many tropical rainforest soils are very poor and infertile.

A tropical rainforest is made up of the following layers. Due to erosion over hundreds of millions of years white and sandy soils can be found in some parts of the Amazon River Basin. The top layer is made up of a thin layer of mulch like substance layered in organic matter from animals above it.

In the soil in a tropical rainforest there is usually a low level of minerals nutrients and organic matter present. Conducted in a natural tropical rainforest at Bukit Baka Experimental Catchment Central Kalimantan Indonesia. 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.
