What are the characteristics of Alfisols soil?

Alfisols are timbered, mineral soils of sub-humid and humid regions which have a high concentration of nutrient cations (Ca, Mg, K, and Na), base-rich, with base saturation of more than 35%, less acidic, high fertility. They are generally fertile and productive soils(Vipinet al, 2016).

What type of soil is Alfisols?

Alfisols are moderately leached soils that have relatively high native fertility. These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated. Alfisols are primarily found in temperate humid and subhumid regions of the world.

Is Alfisols soil good for farming?

Alfisol soil is formed beneath the forest tree cover and is common to the humid subtropical and continental climates. The porous nature, high particle surface area and the water holding capacity make it an ideal type of soil for agriculture.

What color is Alfisols soil?

gray-brown
Alfisols. In the southern part of the Lower Peninsula, the dominant soil color changes from gray to a gray-brown, because of the change in the dominant type of natural vegetation from a pine to a deciduous or broad-leaved forest—a combination of oak, beech, and hickory.

How do you identify Alfisols?

Alfisols generally show extensive profile development, with distinct argillic (clay) accumulations in the subsoil. Extensive leaching often produces a light-colored E horizon below the topsoil.

What minerals are found in Alfisols?

This region, called the argillic horizon, is characterized by a relatively high content of available calcium, magnesium, potassium, and sodium ions. Alfisols are found in the warm-summer subregion of the cool temperate zone, primarily…

What are Alfisols made of?

Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility. “Alf” refers to aluminium (Al) and iron (Fe).

What crops are grown in Alfisols?

Around the world, alfisols are used intensively for agriculture. In the United States, particularly the Midwest and Great Lakes regions, major crops include grains, corn, and hay [3]. Dairy farming is also common in these areas.

Are Alfisols acidic?

All the forms of acidity were highest in Entisols followed by Alfisols and Inceptisols.

Where do Alfisols form?

Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility.

What is Alfisol soil?

Alfisols are moderately leached soils that have relatively high native fertility. These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated.

What are the characteristics of Alfisols?

The combination of generally favorable climate and high native fertility allows Alfisols to be very productive soils for both agricultural and silvicultural use. They are divided into five suborders: Aqualfs, Cryalfs, Udalfs, Ustalfs and Xeralfs. Alfisols occupy approximately 10.1 percent of the global ice-free land area.

Where are Alfisols found in North America?

North America: Alfisols. Alfisols are found in the warm-summer subregion of the cool temperate zone, primarily in the Laurentian mixed-forest vegetation region. They are characterized by an upper horizon leached of iron and aluminum compounds, humus, and clay. These materials accumulate in the subsoil, where they form….

What is the difference between Alfisols and ultisols?

Alfisols have both: (1) a subsurface zone of clay accumulation — either an argillic, kandic or natric horizon; and (2) base saturation of at least 35 percent in the subsoil. This second criterion is what distinguishes Alfisols from Ultisols.
