| Resumo: | A geographic-genetic study of soils located at the northern coastal plain in Nayarit state was conducted, considering as a reference more than 100 profiles gathered from different studies and classified by the World Reference Base. Results proved that in this region there are seven referential groups of soils. The formation of these soils is related with the fluvio-marine influence as well as the leaching of salts and bases, under a current sub-humid tropical climate. Therefore, it is shown that at the upper and medium fluvial coastal plains, the most common soils are Cambisols, Fluvisols and Phaeozems, with a high base saturation without salts, but with a small exchangeable sodium accumulation (hyposodic); whereas the lower fluvial coastal plain, with marine influence, Cambisols are transitionals with Fluvisols (fluvic Cambisols), and these soils and even Fluvisols are mostly affected by salts (salics) and/or exchangeable sodium (sodic and hyposodic). Today, on the fluvial coastal plain, there are only Fluvisols. The area affected by tides, with marine influence, is representative of the saline soils or Solonchaks; however, in the zone of parallel bars to the coast, there are Arenosols and Regosols. These results will serve as a future base for the agricultural and forestry management of this region, in search for a sustainable agriculture. |
