Presencia de esporas de hongos micorricíco arbusculares en suelos del Bosque Alto Andino, Parque Natural Chicaque

Abstract

Among microorganisms in the soil are mycorrhizal arbuscular fungi, which have been little studied in the country in terms of determining their presence and diversity in different ecosystems, but why is it important to determine the presence of mycorrhizae? And why are mycorrhizae important in minimizing the impact of cultural practices carried out by human settlements? Several studies indicate that, in a wide range of conditions, stimulating the growth and activity of mycorrhizae already present in the soil through Environmental management may be sufficient to achieve a significant effect on plant nutrition; However, in highly eroded soils or in the production of seedlings for transplantation, the introduction of mycorrhizae through inoculation seems to be a necessary complementary measure, which minimizes the use of agrochemicals and thus enhances the fertilization with natural agents (Munera & Meza , 2012). Therefore, it is necessary to carry out research work that allows to relate the characteristics of soils in the Andean forests with the presence of arbuscular mycorrhizal fungi. In this sense, the Chicaque natural park presents characteristics of high Andean forest, which in general has been little studied, which is why the present study was advanced, recording the presence of arbuscular mycorrhizal fungi spores through isolation and counting associated with the roots Of different forest species and in turn related to the chemical characteristics of the soil, such as pH and phosphorus available.
