EFFECT OF BIOSOLIDS ON THE PHYSICOCHEMICAL PROPERTIES OF AN INCEPTISOL OF THE MUNICIPALITY OF PUEBLA, MEXICO

Biosolids are an option for improving the physical characteristics and chemical of soils of low fertility since they can incorporate organic matter and nutrients. Therefore, the objectives of this study were to assess how modify the properties of fertility and also to determine if biosolids application represents an environmental hazard. Biosolids increased the content of organic matter, nitrogen, phosphorus and exchangeable bases of soil, potassium and magnesium; while sodium and calcium decreased, the textural class was modified by sandy clay loam to loam due to the incorporation of smaller particles. It was concluded that the biosolids are materials capable of application to agricultural soils to improve their physical and chemical properties if adequated evaluations are carried out to ensure the safety of soils and the trophic network. However, it is necessary to monitor the soils that are incorporated since there is a risk of contamination by a high concentration of nutrients and heavy metals.Key words: macronutrients, soil texture, soil monitoring.
