Wetlands worldwide face increasing challenges due to human activities such as water extraction, deforestation, and overfishing. These ecosystems are crucial for biodiversity, water retention, and purification. In Ecuador, the “Abras de Mantequilla” wetland exemplifies these pressures. It serves as a vital site for studying the interactions between soil fertility and arbuscular mycorrhizal fungi (AMF) in forest ecosystems. The study focused on the soil fertility, particularly in relation to AMF in "Noah Morán" secondary forest within the Abras de Mantequilla wetland. The key role of AMF in improving soil fertility was highlighted. Soil samples were collected from the root zone of four forest tree species i.e., Guazuma ulmifolia, Albizia guachapele, Eugenia pustulescens, Cecropia peltate. The four investigated soil samples had marginal differences in the soil physicochemical propertie...

The objective was to evaluate the germination and sanitary quality of mucuna (Stizolobium spp.) white and black used as green manure in Quevedo, Ecuador. The experiment was conducted at the Laboratory of Environmental Microbiology and Plant, Universidade Técnica Estatal de Quevedo-UTEQ. The seeds of mucuna white and black were from the experimental field in La María 2010 harvest. The work consisted of two treatments for each type of seed of mucuna (white and black), totaling four. In each Petri plates were plated five (5) seeds, ten (10) plates per treatment, totaling 50 in each. Transferred to a growth chamber (incubator) control temperature of 25 °C ± 2 without photoperiod. We evaluated the physiological quality (germination for six days and rate (r) of growth of the radicle) and health (incidence of pathogens) its seeds. The germination was between 68 (BDA medium) and 40% (filter ...
