Characterization and mapping of soil classes of the Lajeado Pessegueiro watershed in Santa Catarina, Brazil

Pedological surveys and physiographic characterization of a watershed are fundamental procedures for planning the soil use. Thus, the aim of this study was to characterize and map the soil classes of the Lajeado Pessegueiro watershed, located in Guarujá do Sul, Santa Catarina, Brazil. The types of land use and occupation, slope classes and physiography of the study area were delineated and described. Data were collected from 19 complete soil profiles and 9 extra samples. Physiographic analysis was performed using prior information on the photopedology of the terrain geomorphological characteristics, climatic conditions, vegetation, land use and geological conditions. The watershed has a predominant undulating relief (406.51 ha). The predominant land use is agricultural, with temporary annual crops (50.09%). The predominant physiography is colluvial erosional slope (35.53%), followed by erosional slope (27.13%), plateau slope (21.55%), alluvial colluvial valley bottom (10.51%) and erosional colluvial slope (5.23%). The soil classes found were Red Nitosols (37.54%), Haplic Nitosols (8.22%), Haplic Cambisols (35.20%), Fluvic Cambisols (3.92%), Red Argisols (10.09%) and Litholic Neosols (5.04%). The data showed the importance of using the physiographic analysis of the area with geoprocessing techniques, assisting pedological surveys with presentation through thematic maps. These maps serve as a base material in studies evaluating land uses, and those aiming to contribute to a better planning of soil use.

Los estudios pedológicos y la caracterización fisiográfica de una cuenca son procedimientos fundamentales para planificar el uso del suelo. Por lo tanto, el objetivo de este estudio fue caracterizar y mapear las clases de suelos de la cuenca Lajeado Pessegueiro, ubicada en Guarujá do Sul, Santa Catarina, Brasil. Se delinearon y describieron los tipos de uso y ocupación de la tierra, las clases de pendiente y la fisiografía del área de estudio.Los datos se obtuvieron de 19 perfiles de suelo completos y 9 muestras adicionales. El análisis fisiográfico se realizó con información previa sobre la fotopedología de las características geomorfológicas del terreno, las condiciones climáticas, la vegetación, el uso de la tierra y las condiciones geológicas. La cuenca tiene un relieve predominantemente ondulado (406.51 ha). El uso predominante de la tierra es agrícola, con cultivos anuales temporales (50.09%). La fisiografía predominante es la pendiente erosiva coluvial (35.53%), seguida por la pendiente erosiva (27.13%), la pendiente de la meseta (21.55%), el fondo del valle coluvial aluvial (10.51%) y la pendiente coluvial erosiva (5.23%). Las clases de suelos encontradas fueron Nitosoles Rojos (37.54%), Nitosoles Hálpidos (8.22%), Cambisoles Hálpidos (35.20%), Cambisoles Fluviales (3.92%), Argisoles Rojos (10.09%) y Neosoles Lithólicos (5.04%). Los datos mostraron la importancia de utilizar el análisis fisiográfico del área con técnicas de geoprocesamiento, ayudando a las encuestas pedológicas con la presentación a través de mapas temáticos. Estos mapas sirven como material base en estudios que evalúan los usos del suelo y aquellos que apuntan a contribuir a una mejor planificación del uso del suelo. Os levantamentos pedológicos e a caracterização fisiográfica de uma microbacia são procedimentos fundamentais para o melhor planejamento da exploração do recurso solo. Objetivou-se realizar a caracterização e o mapeamento das classes de solos da microbacia Lajeado Pessegueiro, Guarujá do Sul, Santa Catarina, Brasil. Fez-se a delimitação e apresentação da área de estudo, dos tipos de uso e ocupação das terras, das classes de declividade e da fisiografia da área. Coletaram-se informações de 19 perfis de solo completos e mais nove amostras extras. A análise fisiográfica foi feita por meio do conhecimento prévio de fotopedologia das características geomorfológicas do terreno, das condições climáticas, da vegetação, do uso da terra e das condições geológicas. O relevo predominante da microbacia é o ondulado (406,51 ha). O uso da terra predominante é de culturas temporárias (anuais) com 50,09%. A fisiografia predominante é a encosta erosional coluvial (35,53%), seguido da encosta erosional (27,13%), encosta em patamar (21,55%), fundo de vale coluvial aluvial (10,51%) e encosta coluvial erosional (5,23%). As classes de solo encontradas foram Nitossolos Vermelhos (37,54%), Nitossolos Háplicos (8,22%), Cambissolos Háplicos (35,20%), Cambissolos Flúvicos (3,92%), Argissolos Vermelhos (10,09%) e Neossolos Litólicos (5,04%). Por meio dos dados gerados evidenciou-se a importância da utilização da análise fisiográfica da área junto às técnicas de geoprocessamento, auxiliando nos levantamentos pedológicos juntamente com a apresentação desses estudos através de mapas temáticos, servindo como material base para estudos de avaliação do melhor uso das terras, assim como estudos que possam contribuir para um melhor planejamento de uso do solo.
