“…Na avaliação da condutividade hidráulica do solo saturado no campo, empregou-se o permeâmetro de Guelph, modificado por Vieira (1998). Mediu-se a taxa constante de infiltração e calculou-se a condutividade hidráulica do solo saturado no campo (Kfs), de acordo com Reynolds & Elrick (1985). Feitas as medições, os dados foram analisados segundo modelos matemáticos propostos por Vieira (1998).…”

Resumo -O objetivo deste trabalho foi avaliar a relação entre atributos micromorfológicos e físicos de um Latossolo Vermelho eutroférrico, sob cultivo de cana-de-açúcar. As amostras de solo foram coletadas nos pontos de cruzamento de uma malha, com intervalos regulares de 10 m, perfazendo um total de 100 pontos, nos horizontes A1 e AB. Os altos valores da densidade do solo, microporosidade e resistência do solo à penetração, e os baixos valores da macroporosidade, porosidade total e condutividade hidráulica do solo saturado, principalmente no horizonte AB, indicaram compactação confirmada pela análise de imagens (micromorfologia).Termos para indexação: Saccharum officinarum, resistência do solo à penetração, condutividade hidráulica do solo saturado, análise de imagens. Soil micromorphology and its relation with physical and hydrical attributesAbstract -The objective of this work was to evaluate the relationship between soil micromorphological and physical attributes in an Oxisol (Rhodic Eutrudox) under sugarcane. Soil samples were collected at the intersection points of a regular grid, with 10 m intervals, comprising a total of 100 points, in the horizons A1 and AB. The higher values for bulk density, microporosity and soil penetration resistance and lower values for macroporosity, total porosity and saturated hydraulic conductivity mainly in the AB horizon, indicated compaction in this horizon, confirmed by image analysis (micromorphology).

“…6). The apparatus is used to measure the steady-state recharge into unsaturated soil required to maintain a constant depth, or head, of water above the bottom of a cylindrical well-hole [53]. For use in Greenland, the apparatus was modified to provide greater stability on uneven ground and during strong wind gusts.…”

Establishing and sustaining agricultural production was a key factor in the success of Norse settlements during the landnám colonisation across the North Atlantic. In light of the occurrence of channel features in several abandoned home-field areas of the Norse Eastern Settlement of Greenland, and the irrigation requirements of presentday Greenlandic sheep-farmers questions are raised: was irrigation used by the Norse settlers of Greenland on their home-field areas? and, if so, how frequently? Modelling of soil chemical, physical and soil-water hydraulic properties integrated with contemporary highresolution climatic data demonstrate a frequent requirement for irrigation. Soil moisture deficits are related to the duration and intensity of winter temperature. Using the winter Dye 3 ice core δ 18 O record as a climatic proxy, the frequency of moisture deficits, based on comparing mean winter temperatures, indicates that there was a frequent irrigation requirement to maintain home-field productivity, increasing throughout the period of settlement until the 14th Century.
