paddy soil, which has high fertility and good conditions in terms of irrigation and drainage, is an important sub-variety of paddy soils in China, with a total estimated area of 200 000 [km.sup.2].
The plant is susceptible to frosts and low temperatures, saline soils, boggy or hydromorphic
soils, low rainfall, coralline soils with poor water-holding capacity (http://www.fao.org/forestry).
Tenders are invited for Brush-cutting restoration and logging services on wetlands and hydromorphic
environments with a view to restoring open areas.
The second experiment with the same irrigated rice cultivars was performed in vessels with a capacity of 9L containing 7kg of a typical hydromorphic
haplic planosol soil (EMBRAPA, 2013).
About 31-35% of mineral soil cover is found in hydromorphic
soils, 0.7-3.0% in Fluvisols and 0.5-2.5% in eroded soils.
Hyland and Sheldon [23, 28] noted hydromorphic
features locally along the transect that were confirmed by rock magnetic properties as likely reflecting localized ponding or a water table that was near to the surface of soils at least seasonally during their formation.

According to Mori , two major soil types are observed in Mateur plain: fluvisol and hydromorphic
and holomorphic soils with high salinity.
Water stress is recurring environmental factors in Rio Grande do Sul since the southern zone of this state is characterized for presenting extensive areas of hydromorphic
soils, poorly permeable and with drainage problems (CUNHA and SILVEIRA, 1996).
The soil is hydromorphic
lateritic on clay sediments (reference: Carte pedologique de reconnaissance a 1/200000, Feuille de Porto-Novo 1975, Benin) and the plant adapts to this kind of soil.
