Tropical Rainforest Characteristics Soil

Due to erosion over hundreds of millions of years white and sandy soils can be found in some parts of the Amazon River Basin.

Tropical rainforest characteristics soil. 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. A thin layer of fertile soil is found at the surface where the dead leaves decompose. The type of clay particles present in tropical rainforest soil has a poor ability to trap nutrients and stop them from washing away.

This article addresses the climate and biodiversity of one of Earths most diverse and iconic biomes. The forests are located in the tropical wet humid regions with an average annual rainfall of around 200-225 cm. Many of these soils are oxisols and ultisols.

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. Some tropical trees have developed huge buttress roots to absorb nutrients from the soil. Soil - Many tropical rainforest soils are very poor and infertile.

Soils remained slightly alkaline pH 7475 with higher concentrations of calcium magnesium and potassium than in acid soils of older rainforests. From a soil point of view cutting down of the rainforest disturbs the natural soil-plant cycle and makes the soils extremely vulnerable to soil erosion and loss of this vital topsoil. A tropical rainforest is made up of the following layers.

Conducted in a natural tropical rainforest at Bukit Baka Experimental Catchment Central Kalimantan Indonesia. Tropical rainforests are characterized by rainfall and evergreen species. Climatic conditions in tropical rainforests have an average of 27 degrees annually and an average rainfall of approximately 200cm with a permanently high humidity.

Characteristics of the tropical forest. Millions of years of weathering have washed most of the nutrients out of the soil. The tropical rainforest biome has four main characteristics.
