Abstract: The use of soil cover is a conservation practice that promotes benefits for the chemical, physical and biological characteristics of the soil, through the maintenance of moisture, aggregation and availability of nutrients, acting intrinsically on its health. Pfeiffer Circular Chromatography (PCC) is a method that allows the qualitative evaluation of soils under different managements. In this sense, the objective of the research was to evaluate in a qualitative way, by Pfeiffer Circular Chromatography, the effect of the covers of mesquite (Prosopis juliflora), elephant grass (Cenchrus purpureus), Indian neem (Azadirachta indica), castor oil plant (Ricinus communis) and the absence of cover, on soil health. The study was conducted at IF Baiano campus Guanambi and had five treatments and five blocks, arranged in a randomized block design, soil health was evaluated by the PCC method. The elephant grass cover provided greater soil aeration, and the castor bean cover stood out among the treatments for presenting better characteristics regarding harmonic interaction, availability of organic matter and soil aeration.
