Estimation of the Retention and Availability of Water in Soils of the State of Santa Catarina

Diego Bortolini, Jackson Adriano Albuquerque


ABSTRACT: Soil water retention and availability are important properties for agricultural production, which can be measured directly or estimated by pedotransfer functions. Some studies on this topic were carried out in Santa Catarina, Brazil. To improve the estimates, it is necessary to evaluate other properties, to analyze more soil types, as well as to use other analysis techniques such as artificial neural networks and regression trees. Thus, the objective of the study was to estimate the field capacity (FC), permanent […]

Characteristics of Soils in Highland Wetlands as a Subsidy to Identifying and Setting their Limits

Maria Tereza Warmling, Jackson Adriano Albuquerque, Jaime Antonio de Almeida, Maria Izabel Warmling


ABSTRACT Palustrine areas and wetlands in particular are fragile ecosystems, with high biodiversity and high ecological productivity, and they provide benefits to society. The aim of this study was to describe and classify the main soils occurring in the wetlands of the Southern Plateau of Santa Catarina, and propose criteria for identification of hydromorphic environments as an aid in demarcation of their boundaries. Soils of four wetlands, in the municipalities of Bom Jardim da Serra, Bom Retiro, Lages, and Painel […]

Soil Solution Nutrient Availability, Nutritional Status and Yield of Corn Grown in a Typic Hapludox under Twelve Years of Pig Slurry Fertilizations

Marco André Grohskopf, Paulo Cezar Cassol, Juliano Corulli Corrêa, Jackson Adriano Albuquerque, Paulo Roberto Ernani, Maria Sueli Heberle Mafra, [...]


ABSTRACT Nutrient content in soil solution may vary in response to the applied amount of pig slurry (PS). Thus, the aim of this research was to evaluate the nutrient content in soil solution and its relationship to nutritional status and yield of corn under 12 years of annual fertilization with increasing doses of PS, soluble mineral fertilizer (MF) and PS combined with MF. The experiment was conducted under field conditions in a Latossolo Vermelho Distroférrico (Typic Hapludox). The treatments consisted […]

Pine Harvest Impact on Soil Structure of a Dystric Cambisol (Humic)

Adriano da Costa, Jackson Adriano Albuquerque, André da Costa, Maria Tereza Warmling, Bruno Afonso Magro


ABSTRACT Traffic of heavy machinery at harvest and log extraction causes structural degradation of the soil, but studies on the effects of forest harvesting on soils with high organic matter content and exchangeable Al are scarce. The objective of this study was to evaluate the effect of mechanized forest harvesting operations on a Dystric Cambisol (Humic) with high organic matter (more 50 g kg1) content and exchangeable Al (more 6,0 cmolc kg-1), reforested with Pinus taeda L. The evaluated harvesting […]

Physical Properties of a Hapludox after Three Decades under Different Soil Management Systems

Franciani Rodrigues da Silva, Jackson Adriano Albuquerque, André da Costa, Sandra Mara Vieira Fontoura, Cimélio Bayer and, Maria Izabel Warmling


ABSTRACT Changes in soil physical properties due to different management systems occur slowly, and long-term studies are needed to assess soil quality. The objectives of this study were to evaluate the effects of soil management systems and liming methods on the physical properties of a Latossolo Bruno Alumínico típico (Hapludox). A long-term experiment that began in 1978 with conventional and no-tillage systems was assessed. In addition, different liming methods (no lime, incorporated lime, and lime on the soil surface) have […]

The use of pig slurry (PS) as fertilizer can affect the soil quality and increase total stocks of soil organic carbon (TOC). However, the effects of PS on TOC amount and forms in the soil are not fully understood, particularly in areas under no-tillage (NT). The purpose of this study was to determine TOC contents and stocks in the particulate (POC) and mineral-associated C fractions (MAC) of an Oxisol after nine years of maize-oat rotation under NT, with annual applications […]
