Resumo(s)
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-tube system was used,and fertiliser rates were adjusted based on the estimated plant nutrient demand.
Soil moisture content was measured during the same period at 5 cm depth intervals down to 90 cm depth.Soil carbon content
was measured at planting,30 months after planting and54 months after planting.Interrelations between fine-root dynamics, soil
moisture , and soil carbon content are discussed.
