Determinación de la capacidad de intercambio catiónico del suelo y su correlación con el contenido de cationes intercambiables de las plantas del género Siparuna.

Abstract

Abstract:Given its natural wealth, the Province of Loja has numerous plant species, one of them being plants of the genus Siparuna that have potential for research from an analytical point of view since it has pharmacological properties. The main objective of this research was to determine the content of interchangeable cations in soils and their correlation with the content of interchangeable cations in plants of the genus Siparuna, for which samples were collected in five areas of the province of Loja. The macro and micronutrients determined in soil and foliar were K, Ca, Mg, Na, Mn, Fe, Cu, Zn, Si and Al. The analyzes were performed by flame Atomic Absorption Spectrophotometry. The highest concentrations found in soils and leaf tissue correspond to calcium, the lowest concentrations were manganese and iron in both soil and foliar. The soil-plant correlations were significant positive mainly in the micronutrients evaluated in relation to the physicochemical characteristics of each zone.
