Alisol | Soil Classification, Soil Structure & Soil Texture
网页Alisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Alisols are highly acidic, poorly drained soils prone to aluminum toxicity and water erosion. Liming and fertilization are essential to …
Alisol - Wikipedia
网页An Alisol is a Reference Soil Group of the World Reference Base for Soil Resources (WRB). [1] Alisols have an argic horizon, which has a high cation exchange capacity. In the subsoil, the base saturation is low. There exist mixed forms, for example 'Stagnic Alisol', that are mainly Alisol, but also contain components that are found in Stagnosols.

ALISOLS (AL) - ISRIC
网页ALISOLS (AL) The Reference Soil Group of the Alisols comprises strongly acid soils that have accumulation of high activity clays in the subsoil. They occur in humid (sub-)tropical and warm temperate regions, on parent materials that contain a substantial amount of unstable Al-bearing minerals. Ongoing hydrolysis of

Alisols - ISRIC
网页Alisols occur in the tropics and subtropics, and in the warm temperate regions of the world in relatively young landscapes. The high level of exchangeable aluminium in these soils is caused by rapid weathering of secondary high-activity …
Alisols - Oxford Reference
网页A reference soil group in the soil classification scheme used by the FAO. Alisols have an argic B horizon (see argic horizon) with a cation-exchange capacity of more than 24 cmol c /kg clay and a base saturation of less than 50% within 100cm of the soil surface.
Alisols - SpringerLink
网页2016年1月1日 · Alisols are traditionally used in shifting cultivation and for low volume production of undemanding crops. In the past decades, Alisols have increasingly been planted to Al‐tolerant estate crops such as tea and rubber, and also to oil palm.
Alisols - an overview | ScienceDirect Topics
网页Alisol A ( 16 ), which is a protostane-type triterpene, is also a natural product that comprises 0.05%–0.1% of rhizomes of Alisma orientalis Juzep ( Murata et al., 1970 ). It carries four hydroxyl groups, providing the opportunity to have a large number of derivatives.
Alisols-Acrisols - SpringerLink
网页2017年10月1日 · Alisols and Acrisols are acidic soils with lower pH in their surface horizons compared to the deeper ones. However, in some cases, their pH varies in the profile depending on the organic matter content. The same is true for their CEC and base saturation. Many factors contribute to the acidification in these soils.
网页Alisols are typical soils of the humid tropics and subtropics where they occur on younger geomorphic surfaces such as the hill region of Yanshan, Eastern China. Here the soil comprises of two parent
