ABSTRACT The study of the relationships between the yield potential of forest stands and the conditions offered for plant development is fundamental for the adequate management of the forest when aiming at sustainable high yields. However, these relations are not clear, especially in commercial forests, on rugged terrain where relationships between the landscape, soil, and plants are more complex. Considering this, we tested the hypothesis that the morphological aspects of the soil conditioned by topography are the main limiting factors […]

MINERAL RESERVES OF K DETERMINED BY DIFFERENT METHODS IN SUBTROPICAL ARGISSOLOS SOILS

Estefane Chaves, Fabrício de Araújo Pedron, Vander Freitas de Melo, Ricardo Simão Diniz Dalmolin

Integration of chemical extraction methods and X-ray diffraction can broaden understanding of K+ forms and reserves in soil fractions, and their potential release to plants. The aim of this study was to use chemical extraction methods to estimate mineral reserves of K+ in sand, silt, and clay from subtropical soils; to associate extraction mechanisms with the forms of K+ released; and to monitor the dynamic of K+ release in a kinetics study. The sand, silt, and clay fractions of the […]

Boundary between Soil and Saprolite in Alisols in the South of Brazil

Despite numerous studies conducted on the lower limit of soil and its contact with saprolite layers, a great deal of work is left to standardize identification and annotation of these variables in the field. In shallow soils, the appropriately noting these limits or contacts is essential for determining their behavior and potential use. The aims of this study were to identify and define the field contact and/or transition zone between soil and saprolite in profiles of an Alisol derived from […]
