Caracterización edafológica de los suelos El Triunfo, San Carlos y Alto Humayacu para plantaciones de balsa (Ochroma pyramidale Cav.ex Lam) provincia de Orellana.

Abstract

The Environmental Management Department of the Decentralized Autonomous Government of the province of Orellana lacked technical information on pedological studies of the productive area. It difficulted to make decisions regarding forestry use. In this aspect, for this research, no physicochemical evaluations of the soils were carried out in the sectors that were accredited to the institutional project. Therefore, the general objective of this sutdy was to determine the pedological properties of the soils of the towns El Triunfo, San Carlos and Alto Huamayacu in the province of Orellana for balsa plantations (Ochroma pyramidale Cav. ex Lam). The methodology implemented had a mixed approach. A complete randomized design was used, complemented by a detailed sample size calculated with the respective equation. The field procedure was necessary in conjunction with procedures in the Soil Laboratory of the Faculty of Natural Resources-ESPOCH for the determination of the physical-chemical properties of soils.
