When the soil is acidic there is little difference and therefore little absorption of nutrients from the soil.

Tropical rainforest characteristics soil. 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. Very high annual rainfall high average temperatures nutrient-poor soil and high levels of biodiversity species richness. Climatic conditions in tropical rainforests have an average of 27 degrees annually and an average rainfall of approximately 200cm with a permanently high humidity.

The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. Some soils are also exposed. This article addresses the climate and biodiversity of one of Earths most diverse and iconic biomes.

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. Transpiration from the evergreen trees results.

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. The tropical rainforest is often in the news for various reasons. There are major concerns about deforestation of it and the consequent damage to the soil.

Characteristics of soils in the tropical rainforest biome of Biosphere 2 after 3 years. This high rate of decomposition is the result of phosphorus levels in the soils precipitation high temperatures and the extensive microorganism communities. Ground level - contains less vegetation due to the dark damp conditions a thick layer of decomposing leavesand the.
