Abstract	The monitoring of biochemical parameters as enzyme activities and those related to microbial biomass and basal respiration can be relevant in the study of the quality and functionality of natural soils and those related to traditional farming systems and/or ecological and sustainable management systems. In this paper there were developed indices of soil quality (ISQ) from the study of the temporal fluctuations and the effect of coffee varieties on some biochemical properties (enzyme activities), microbiological (basal respiration, microbial biomass and the ecophysiological indexes) and physicochemical as indicators of soil quality under agroforestry systems. Soil microbiota showed sensitivity to the changes by time sampling and variety, and in soils with the Caturra variety coffee was metabolically more efficient in the use of energy substrates during the rainy season. On the other hand, AA, DA enzymatic activities were sensitive to changes by time sampling and variety; DH and protease, were susceptible to temporary fluctuation, while the β-glucosidase and urease were the least sensitive since they showed no significant differences for seasonality or varieties in the soils studied. The ISQ show a similar trend for both developed with the chosen variables from the ACP as well as developed from the variables that contribute to discrimination in the ACCP. These ISQ, were effective in discriminating varieties and climatic times of sampling in the systems studied.
