The minirhizotron technique was used to study the temporal dynamics of fine-roots over a 10 month period in a Eucalyptus plantation in central Portugal.Four treatments were applied:a control without irrigation or fertilisation( C), fertilisation twice per year (F), irrigated without fertilisation( I), and irrigated and fertilised once each week with fertiliser in the irrigation water (IL). In I and IL a drip-tu...
The distribution along the soil profile of Eucalyptus globulus root biomass was followed in a plantation in central Portugal at 1, 2 and 6 years after planting, using an excavation technique. The experimental design consisted of a control (C)and 3 treatments: application of solid fertilizers twice a year (F), irrigation without the application of fertilizers (I) and irrigation combined with liquid fertilizers (...
Poster Paper ; Water and nutrients were supplied to an Eucalyptus globulus plantation in a controlled experiment in west central Portugal. The trees were planted in a sandy soil at a spacing of 3x3 m. The experiment consisted of four treatments: irrigation, irrigation plus fertilization, fertilization without irrigation, and a rain fed and unfertilized control. The quantification of root biomass was carried ou...
The variation in growth of the fine roots of blue gum (Eucalyptus globulus Labill. spp. globulus)in the 0-40 cm soil layer was studied from March 1982 to March 1983 at Quinta do Fradouro, Óbidos, Portugal. A mesh bag method was used; bags of nylon net were inserted into a clay soil and a sandy soil and filled with root-free soil. They were resampled after 2, 4, 6 and 12 months in both places and in a separate s...
