O solo é um recurso natural imprescindível para o desenvolvimento dos seres vivos e de inúmeras atividades antrópicas. Para além disso, possui papel fundamental na prestação de diversos serviços ecossistêmicos como regulação do ciclo do carbono, do ciclo da água e de vários nutrientes, por isso é de suma importância o estudo dos solos para avaliar suas condições, sua aptidão e técnicas de manejo para uma gestão sustentável deste recurso. No entanto, por apresentar um ciclo de renovação lento e que excede em muito o período de longevidade humana, é definido como um recurso natural não renovável. Nessa premissa, o presente estudo tem por objetivo avaliar as propriedades físico-químicas do solo em áreas de montanha com diferentes teores de matéria orgânica e buscar relações estatísticas entre essas propriedades. As áreas de estudo localizam-se em três regiões de montanhas: Serra de Montesinho (SM), Serra da Nogueira (SN) e Serra da Coroa (SC). Constatou-se que, assim como as propriedades físicas, as propriedades químicas dos solos são afetadas pelo teor de matéria orgânica e o uso do solo. Partindo de uma análise global dos dados amostrados, observa-se que os três locais estudados apresentam basicamente comportamentos distintos em relação a cada parâmetro analisado.

In this premise, the present study aims to evaluate the physical-chemical properties of the soil in mountain areas with different organic matter contents and to seek statistical relationships between these properties. The study areas were located in three mountain regions: Serra de Montesinho (SM), Serra da Nogueira (SN) and Serra da Coroa (SC). A conclusion was reached that just like the physical properties, the chemical properties of the soils are also affected by organic matter content and soil use. Based on an overall analysis of the sampled data, it is observed that the three studied sites present basically different behaviors in relation to every parameter analyzed.
