Atributos químicos, físicos e mesofauna edáfica de solos em áreas produtoras de hortaliças no 9º distrito do Município de Pelotas - RS

Abstract

This study aimed to determine the chemical, physical attributes and edaphic mesofauna (mites and collembola) in soils of 12 family farms, vegetable producing, located in the Municipality of Pelotas-RS, 9th district, Monte Bonito. The soil samples to be analyzed were collected, in the 0-0,20m (chemical and physical attributes) and in the 0-0,10m (edaphic mesofauna) in areas cultivated with vegetables and selected according to the fertilization is made, also collected in areas that were not being used by the producers. Were analysed chemical characteristics (base saturation, aluminun saturation, CTC pH7,0, pH, organic matter, P, K, Ca, Mg, Cu, Zn, Fe, Mn, B, S), physical characteristics (particle size, soil density , total porosity, macroporosity, microporosity) and biological characteristics (Shannon index (H), Pielou index (e), frequency coefficient (Cf), constancy (C) and mite/plunger ratio (A/C) ). Based on the results it is concluded that the soil nutrients showed high values, the density of the soil showed values conducive to root development and the edaphic mesofauna is out of balance.
