Gray hydromorphic soils are imperfectly to poorly drained soils that occur on the coastal fringes of the Hawaiian Islands on surfaces of Pleistocene to Recent age. Mottling is characteristic of the soils, and gley horizons occur in the more hydromorphic soils in the group . As the soils become hydromorphic, soil color values increase and structures deteriorate. Halloysite is the dominant clay m...

Traditional winegrowing areas are located in temperate climate zones and allow to produce grapes only once per year. Tropical wines have been elaborated in India, Thailand, Venezuela and Brazil and present another kind of viticulture, as compared with countries located in temperate climate zones. Northeast of Brazil started wine production twenty six years ago. This region vines can produce two...

The Cerrado–Amazonia transition harbors forest and savanna formations under the influence of pronounced climate seasonality; however, water use strategies this key region is not yet well understood. This study aimed at deciphering in intra- interspecific variability leaf potential regulation among species across three distinct vegetation types (typical cerrado, cerradão, semideciduous seasonal ...
