Soil quality is essential to ensure the sustainability of agro-ecosystems. Tensile strength is one of the indicators frequently used for monitoring soil quality, being influenced by several factors, such as the size and shape of the aggregate. In this research, the hypothesis that the use of a single form of soil aggregates reduces the variability in the evaluation of the structural quality of soils was conside...
The fraction of the volume of soil occupied with air is an essential part to guarantee the growth of the cultures. Assuming that less than 10% of aeration porosity is sufficient to guarantee the development of the plants, provided that other attributes of the pore space remain functional; and that the magnitude of this effect is dependent on soil density, the objective of this work was to evaluate the effects o...

O uso de substratos é um fator de extrema importância na produção de mudas de espécies florestais, sobretudo por proporcionar o seu rápido desenvolvimento. A presente pesquisa teve o objetivo de avaliar o efeito de diferentes substratos na produção de mudas de Pithecellobium dulce (Roxb.) Benth. Os tratamentos foram constituídos de subtratos obtidos de cinco misturas, nas seguintes proporções: S1 (solo + arei...
