These soils belong to Alfisols, Vertisols, Aridisols and Entisols
. For each soil series, a composite soil sample (~50 kg) was collected randomly from eight points by an auger at depth of 0-30 cm (Ap horizon).
According to Luciano (2012), the Entisols
and Inceptisols of the Southern Plateau of Santa Catarina have physico-hydrical and chemical restrictions for the implantation of altitude vineyards, since they have low effective depth of the profile, great stoniness and rock outcropping.
Samples were drawn from 18 high silt-soils, under a no-tillage system from the state of Rio Grande do Sul and categorized as Litholic and Regolith Entisols
The soils of this catchment were classified as Ultisols, Oxisols, Entisols
Ichauway is situated within the Dougherty Plain physiographic district, which is characterized by marine and fluvial deposited parent materials that have developed into Entisols
and Ultisols over highly fractured Ocala limestone with a flat to rolling karst topography (Beck and Arden, 1983; Hayes et al, 1983; Couch et al.
The soils of the experimental areas are classified as Entisols
according to the United States Department of Agriculture (USDA) taxonomy.
Pedogenic factors, especially the varying climate and topography, have caused the formation of various soil orders including Alfisols, Mollisols, Aridisols, Entisols
, and Inceptisols.
It is located in the Major Land Resource Area 40 of the Sonoran Desert (Natural Resources Conservation Service, 2006) and has soils that are primarily classified as Aridisols, with small areas of Entisols
[5.] Eden T Uptake and Response of Haricot Bean (Phaseolus vulgaris L.) Varieties to Different Levels of Phosphorus Application on Entisols
The soils of the studied fields were entisols
, and they were classified as Fluvent and Orthent at the suborder level, following the Soil Survey Staff .
Four types of soils, i.e., entisols
, inceptisols, alfisols and vertisols, are present in the study area.
