In the subtropical regions of southern Brazil, rainfall distribution is uneven, which results in temporal variability of soil water storage. For grapes, water is generally available in excess and water deficiency occurs only occasionally. Furthermore, on the Southern Plateau of Santa Catarina, there are differences in soil properties, which results in high spatial variability. These two factors affect the composition of wine grapes. Spatio-temporal analyses are therefore useful in the selection of cultural practices as well as of adequate soils […]

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component […]

The description of soil hydrological processes is relatively complex, especially in the case of moisture, which is influenced by edaphic, topographic, climatic and vegetation factors. Under field conditions, an adequate sampling strategy is required to estimate soil moisture, considering variations in time and space. To represent the soil moisture adequately with less sampling effort and cost, the concept of temporal stability has often been applied. This study was carried out with the objective of analyzing the temporal stability of the […]
