What is Latosols soil?
Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. Latosols are red or yellowish-red in colour throughout and they do not have distinct horizons like a podsol.
How are latosol soils formed?
Laterisation is the dominant process in forming latosols. Laterisation is a combination of deep leaching and chemical weathering. These combine to dissolve all mineral except iron and aluminium. If soil erosion removes the loose topsoil, iron and aluminium is exposed.
What is the definition of latosol in geography?
Definition of latosol : a leached red and yellow tropical soil.
Why is soil red in the rainforest?
It is red in colour because it is rich in iron. Due to heavy rainfall the nutrients are quickly washed out of the soil.
Are Latosols acidic?
Latosol is an acidic red soil and occurs in the tropical rainforest biome. Laboratory experiments were performed by leaching the soil columns with the SAR at a pH range from 2.5 to 7.0 over a 21-day period.
Are oxisols fertile?
Oxisols (from French oxide, “oxide”) are very highly weathered soils that are found primarily in the intertropical regions of the world. Despite low fertility, Oxisols can be quite productive with inputs of lime and fertilizers.
What is arid and desert soil?
Arid soils (or desert soils) are a soil order in USDA soil taxonomy. Aridisols (from the Latin aridus, for “dry”, and solum) form in an arid or semi-arid climate. Aridisols have a very low concentration of organic matter, reflecting the paucity of vegetative production on these dry soils.
What is the litter layer of soil?
The litter layer is defined as the layer of mainly dead plant organic material present on top of the mineral soil surface (Figure 1). It is composed of debris in different stages of decomposition.
Which crop is suitable for red soil?
Crops in Red Soils The red soils, with the proper use of fertilizers and irrigation techniques, give good yield of cotton, wheat, rice, pulses, millets, tobacco, oil seeds, potatoes and fruits.
What is the meaning of latosol?
Definition of latosol : a leached red and yellow tropical soil Other Words from latosol
What are the factors affecting latosols?
Factors affecting latosols. 12. 5. Time • Deep latosols result from the rapid weathering of parent material and the fast breakdown of organic material by fungi, bacteria and other living things. • Tropical regions were not affected by the last ice age and so have had many thousands of years to develop.
What is the pH of latlatosol?
Latosol is a typical variable-charge soil, which carries comparable positive and negative charges at pH values in the range of 3–6.5.
What is the difference between latlatosols and podsols?
Latosols are red or yellowish-red in colour throughout and they do not have distinct horizons like a podsol. The red colour comes from the iron oxides in the soil. They are deep soils, often 20-30 m deep whereas podsols are 1-2 m deep.
