“…There are closed basin or dry valleys in various sizes and shapes, poor drainage, and hilly up to ramps landform. The soil classification in Karst are Entisol, Mollisol, Alfisol, Vertisol, Inceptisol [17][18][19][20]. Karst soils are taken from five locations (Gunungkidul, Wonogiri, Grobogan, Buayan Kebumen, and Padalarang Bandung) around the limestone hills with varies pH from slightly acid to alkaline.…”

With the goal of assessing possible impacts of fish farming in great-volume cage systems on the water quality of a reservoir, the authors provided abiotic data from 72 samples obtained before and after farming site implementation. The figure shows the principal components analysis results for seven limnological variables. The highest dissolved oxygen (OD) concentrations were observed before the fish farm became operational. During the post-production period, the highest phosphorous (PT) and ammonium (NH4) concentrations were observed as well as high conductivity and turbidity values. Authors concluded that fish farming in cage systems located in Solteira Island Reservoir, Brazil, caused significant temporal and sudden spatial changes in water physical and chemical variables.

This study characterized the morphological, physical and chemical attributes of sandstone-derived soils at the Cerrado of the Piauí State, Brazil, in order to identify evolutionary standards. The study was carried out with five representative soil profiles identified as P1-RY (Typical Flavic Psychotic Neosol - Aquents), P2-PA (Typical Dystrophic Yellow Argisol - Alfisol), P3-RL (Fragmentary Litholic Distrophic Neosol - Psammenit), P4-RQ (Typical Ortic Quartzenetic Neosol - Orthents) and P5-PV (Typical Dystrophic Red Argisol - Ultisol). Soil samples were submitted laboratory analysis described morphologically. In general, the soils presented high sand content, low pH, low content of exchangeable bases and low cation exchange capacity (CEC). Organic matter governed the CEC in most cases, suggesting dependence of organic matter in the supply of charges. These soils showed a low degree of weathering, but with iron of high crystallinity. Thus, the relief and the parent material are the major important soil-forming factors at the Cerrado of the Piauí State. Moreover, these soils are young, with the soils from the Piauí Formation being more evolved. However, the sandstones from the Canindé Group apparently are providing lithological secondary minerals for the soil.
