Mycorrhizae are a mutualistic symbiotic associations between roots of plants and certain soil fungi. They can be used as an alternative to increase soil fertility, contributing the absorption and recycling of nutrients. This work evaluated the arbuscular mycorrhizal fungi population in five systems; secondary forest (S1), primary forest (S2), degraded pasture (S3), improved pasture (S4) and agroforestry association (S5); in regard to its distribution according to season, depth and plant system. In addition, morphotype diversity were evaluated in the systems evaluated. The results obtained show that the effect of the sampling season on the number of spores of arbuscular mycorrhizal fungi varies between systems, with more spores founded during the wet season in systems S2 and S4 with maximum values of 0.42 and 3.76 spores per gram respectively and during the dry season in systems S1, S3 and S5 with maximum values of 0.54, 2.42 and 1.16 spores per gram respectively. On the other hand, it was determined that the abundance of spores in the 0-15 cm layer is greater than in the 1530 cm layer with values ranging between 0.18 and 2.42 spores per gram of soil for the 0-15 cm layer and 0.07 and 1.19 spores per gram for the 15-30 cm layer. Similarly, the abundance of arbuscular mycorrhizal fungal spores according to the system from which they were isolated can be ordered as S4> S3> S5> S1 / S2. Finally, it was determined that the diversity of spore morphotypes of arbuscular mycorrhizal fungi for systems S1, S2, S3, S4 and S5 were 16, 17, 40, 17 and 26 different morphotypes, respectively
