A majority of the soils in this area are Alfisols and Ultisols. These soils are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place. In the tropical rainforest, however, rainfall is year round, and can be daily. This strips out most of the nutrients.A majority of the soils in this area are Alfisols and Ultisols.

This strips out most of the nutrients.
Tropical soils are found under very hot conditions, and high yearly rainfall. They are the worlds oldest soils. They are so old, that they are RUSTY! These soils have little ORGANIC MATTER, and very little NUTRIENTS!
Over two-thirds of the world’s rainforests, and three-fourths of the Amazonian rainforest can be considered “wet-deserts” in that they grow on red and yellow clay-like laterite soils which are acidic and low in nutrients.
Soil – Many tropical rainforest soils are very poor and infertile. … 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.
One reason the rain forest soil is so poor is that most of the nutrients are stored in the plants themselves. In any forest, dead organic matter falls to the ground, providing valuable nutrients for new growth. In cooler or drier climates, the nutrients build up in the soil.
Though tropicals are a diverse group of plants, they generally prefer a loose, acidic, well-drained, fertile soil high in organic matter. Common tropical plants, like cannas and bananas, will grow in any good soil, but this mix will help them attain optimal growth.
Tropical rainforests also have high humidity; about 88% during the wet season and approximately 77% in the dry season. … In fact, rainforest soils are nutrient-poor because nutrients are not stored in them for very long. The heavy rains that occur in rainforests wash organic material from the soil.
The majority of tropical soils have shades of colour varying from yellow and brown to red. The reddish colour reflects the presence of iron oxides that form as a result of chemical weathering.
The tall trees in the rainforest often have buttress roots on their sides. Buttress roots allow a tree growing on thin soil to grow high into the air. They provide support for that tree, preventing it from falling down.
Tropical Red Soils They are found in equatorial climates and are a result of chemical weathering. … Weathering breaks down the iron oxide (rust) in the soil giving it a reddish colour. It is a very fertile soil until deforestation and heavy rainfall quickly leaches it.
The soil of temperate grasslands and savanna grasslands are usually mollisols. In the savanna grasslands, however, the soil contains more sand and water drains away quickly. Mollisols are soils with a thick, dark upper layer that is extremely fertile from the growth and death of the of grasses.
Tropical soils may often be described as being thin. This is certainly not so – did you know that tropical soils are among the deepest in the world! Many tropical soils have been under forest cover for millions of years. … So how does such a lush vegetation exist if the soils are so depleted of nutrients.
The rainforest nutrient cycling is rapid. … However, as these nutrients are in high demand from the rainforest’s many fast-growing plants, they do not remain in the soil for long and stay close to the surface of the soil. If vegetation is removed, the soils quickly become infertile and vulnerable to erosion.
Un-composted material such as saw dust or wood shavings are not recommended as they require nitrogen for decomposition and this will rob the plants of their needs. Any or all of these products make excellent soil conditioners regardless of soil type (i.e. clay or sandy):
For container planting, look for a lightweight, commercial potting mix labeled for containers. Add in earthworm castings for extra organic matter, and you’ll have a mix ideal for tropical plants. Low-phosphorus fertilizers encourage abundant tropical hibiscus blooms.
In fact, temperate clays are surprisingly common, especially in younger soils or those formed under drier conditions or where drainage isn’t good. A true tropical soil (one whose clays are mainly I:1 or hydrous oxides) requires good drainage, centuries of weathering, and lots of rainfall and leaching to form.
Because the soil in many rainforests can be poor, tree roots often grow near the ground surface in order to get the nutrients it needs to grow. … So many trees have what are called buttress roots—roots that grow out from the tree trunk and which help to support the tree.
…rainforest trees, large woody prop roots develop from adventitious roots on horizontal branches and provide additional anchorage and support. Many bulbous plants have contractile adventitious roots that pull the bulb deeper into the ground as it grows.
Examples of Plants found in the Tropical Rainforest:
Orchids, Philodendrons, Ferns, Bromeliads, Kapok Trees, Banana Trees, Rubber Trees, Bam- boo, Trees, Cassava Trees, Avocado Trees.

|Black soil||Black regur soil in Buldhana, Maharashrta|
|Red and yellow soil|
|Laterite soil||Abandoned laterite quarry in Angadipuram, Kerala|
|Arid soil||Arid land in Chandeni, Haryana|
a soil formed under broad-leaved forests in humid subtropical regions, chiefly on parent material fromclayey shales. It has an acid reaction and low humus content, and its yellow color is caused by the presence of ferric hydroxide.
Deciduous forests have soils called Alfisols. These soils do not have a bleached E horizon, but do have clays that accumulate in the subsoils. Alfisols are very common in the Midwestern region, and are the most fertile type of forest soils. In the Southeastern US, there are coniferous forests and temperate forests.
Typical temperate deciduous forest soils are mull soils, which have a high level of organic matter especially close to the surface that is well mixed with mineral matter. Variations in soil materials and fertility have a strong influence on the types of trees that will dominate the forest.
All parts of the rainforest (climate, water, soils, plants, animals and people) are all dependent on one another. … This makes the top of the soil high in nutrients so plants grow quickly; this is why many trees have their roots on the surface. 3. Plants pass on their nutrients when they are eaten by animals.
Soils in tropical rainforests are typically deep but not very fertile, partly because large proportions of some mineral nutrients are bound up at any one time within the vegetation itself rather than free in the soil.
The warm and very wet climate provides perfect conditions for plant growth. … Species have adapted to the conditions of the rainforest, eg trees and plants have shallow-reaching roots to absorb nutrients from the thin fertile layer in the soil.
