POZO-GALVES, Crecencio et al. Characteristics and classification of Ferruginous nodular gley soils under intensive rice crop production from Los Palacios. cultrop [online]. 2017, vol.38, n.4, pp.58-64. ISSN 0258-5936.

Soils under intensive rice crop production, for more than 50 years were studied to describe problems in physical properties and morphological characteristics and to classify the soils by the New Version of Cuban Genetic Soil Classification, American Soil Taxonomy and the Word Reference Base, taking into account the showed evidences. The results indicated soils affected by gleyzation process, observed at soil depth equal or higher than 50 cm, where iron and manganese nodules where abundant. There were evidences of not good conditions of soil physic properties, characterized by an increase of bulk density and a reduction of total porosity. In addition, it was observed poor soil fertility, in both profiles, characterized by low levels of nutrients. However, such behaviors there were not enough to define anthropic effects by the existence of an Anthraquic or hydragric horizon, due to the absences of a low pan and other diagnostic characteristics

Keywords : morphological characteristics of soil; soil fertility; physics-chemical properties of soil.
