Soils Savannas are different from the others in Venezuela The forests also differ across regions, since the High Ventuari of Ocamo, Alto Orinoco, are not the same type as those located on rivers Atabapo, Temi, Guainia Pasimoni, or those accompanying them in their course to Arm Casiquiare. Neither the soils that sustain this high vegetation may be equally permeable to the savannas, but certainly not cease to be acidic. There is in Amazon a clear understanding of soil quality, it can be pointed in the general sense that they are relatively acidic, not very suitable for agriculture, being able to see that some are more suitable for livestock. So far it is considered that given the poor quality of these soils, by subjecting them to plant crops, to be complemented by minerals lacking, which is very difficult and economically unfeasible, and other technical causes. There are good prospects for testing banana crops and native plants known and used: clog, pineapple, yucca, copoazú, Merey, Coco, Cocoa, Coffee, Sugar, Loquat, Temares. We must destroy the myth created in relation to the fertility of these soils. Only in the parts where vegetation is thicker, forming a surface layer of humus that nourishes the roots. When the vegetation is destroyed to make conucos thin topsoil that was also destroyed by the action of fire, prompting a rise in temperature further and causing erosion due to soil washing, thereby encouraging climate change and ecological imbalance. According to studies undertaken so far, the land that could be classified as agricultural may occupy an area equivalent to only 19% of the territory and could be located in the upper valley of Manapiare under Ventuari, Alto Orinoco, upper arm Casiquiare a strip or elevation between Santa Barbara and San Fernando de Atabapo. This percentage noted before, is estimated to cover a little more than three million hectares, although subject to certain limitations and individuals. With reference to the savanna areas of land, regarded as potentially developable for the possible use of livestock, cover 7% of the total state area. They are flat lands near the river courses Ventuari and Orinoco, but their use is also subject to many natural physical limitations. As a large area covering nearly 54% of lands unsuitable for any development before ¬ scores two, soils must be protective for forestry and therefore its use should be spent only for recreation, wildlife , care of watersheds and aesthetic purposes as national parks, etc.. Many of these lands they give corre ¬ mountain slopes, some exceeding 30% in slope, with great dangers of erosion, because they also have thin soils, located in the foothills or high plateaus. |

and Colombia with sedimentation of the Andes. Are more extensive to the north, and the rest are state resembling spots, be characterized by sandy soil with high acidity. We note that in the driest parts, especially where there is plenty of rocks, in addition to grasses, there is an abundance and variety of bromeliads, many of which are distinguished by the quality of retaining water in large quantities.
