Evaluación de dos índices de diversidad para definir sustentabilidad biológica en una finca agrícola, del cantón Urdaneta

Abstract:

SUMMARY The investigation was carried out in the properties of the property "Villa Luz" located to 3,5 km of the enclosure "Dust cloud" in the road of Ricaurte-Ventanas. He was carried out a sectorización of the property, obtaining five investigation lots: Cocoa without shade, Corn, Bean, fruit and cocoa with shade. The efficiency of two indexes of biological diversity was evaluated, on the populations of plants vascular present in the property, by means of the count and classification taxonómica of individuals of different botanical families. A sampling was used in all the properties, the selected material was classified with key taxonómicas authorized by the UICN in the laboratories of the FACIAG. The floor samples collected by each lot, they were taken to the laboratory of floors of the South Coast Station of the INIAP. The results determined an index of Margalef 2,03; the same one considered half. Also the values found in the index of Shannon-Wienner (0,68) a low variability of species and individuals showed. The number of families found in the area of the property was 17 with 26 goods, being the family Myrtaceae that of more number. You counted in total 84968 individuals, being bigger the quantity of especímenes of Corn, Cocoa and Bean. The values of Match (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Iron (Faith), Get paid (Cu), Manganese (Mn) and Zinc (Zn), they went bigger to the reference range. The Nitrogen (N) and Sulfurate (S) they had low ranges in certain lots; having the Boron (B) I lower registration in all the lots muestreados. The values of organic matter were means and first floor, with a pH among lightly sour to fairly sour.
