Catena of Ultisols from southeastern Brazil: Assessing variation within and among pedons
2023, Geoderma RegionalDramatic shifts in fungal communities following application of hairy vetch (Vicia villosa Roth L.) in upland of Ultisol
2021, European Journal of Soil BiologyCitation Excerpt :Besides, long-term mineral fertilizers might increase abundance of soil-borne plant fungal pathogens [6]. Though the Ultisol regions have favorable natural resources such as enough light, suitable temperature and adequate moisture, the cultivated crops are associated with relatively low productivity [7]. Therefore, it is urgent to seek out new practices to achieve the sustainable development of agriculture in Ultisols of southern China [8].
Soil-geomorphology relationships of alluvial fans in Costa Rica
2020, Geoderma RegionalCitation Excerpt :Soil mapping units were mainly composed of Ultisols, represented as distinct taxonomic subgroups on soil associations established on the soil map. Occurrence of Ultisols on distinct landforms, is led by their structural stability over periods of time, allowing formation of argillic or kandic horizons (West et al., 1998; Buol et al. 2011). Pedogenesis of Oxisols can be explained by old alluvial materials deposited in the wettest periods between 85 and 45 ka reported in Costa Rica (Lachniet et al., 2009) and consistent with regional moist periods in Guatemala (Hodell et al., 2008) and Panama (Shadik et al., 2017).

2015, Science of the Total EnvironmentCitation Excerpt :We recently reported on the hydrologic impact of strip compared to conventional tillage in the Atlantic Coastal Plain region of the southeastern USA (Bosch et al., 2012; Endale et al., 2014). Ultisols, the predominant soil order in the region, have clay rich subsurface horizons that restrict internal drainage and promote lateral subsurface flow (West et al., 1997; Shaw et al., 2001). Over an 11-year period in which 7 cotton and 4 peanut crops were produced, the annual average lateral subsurface flow was 18% and 10% of rainfall plus irrigation from paired strip and conventionally tilled fields respectively.
