Soil organic carbon-stock changes in Flemish grassland soils from 1990 to 2000 (2009)

Mestdagh, Inge, Sleutel, Steven, Lootens, Peter, Van Cleemput, Oswald, Beheydt, Daan, Boeckx, Pascal, ...

Total soil organic-carbon (SOC) stocks for grassland soils in Flanders (N Belgium) were determined for the Kyoto Protocol reference year 1990 and 2000 in order to investigate whether these soils have...

Temperature integration of Hedera helix L.: Quality aspects and growth response (2009)

Pollet, Bruno, Steppe, Kathy, Dambre, Pieter, Van Labeke, Marie-Christine, Lemeur, Raoul

Reducing energy use in greenhouses contributes to the profitability of horticulture. Important energy savings can be realized through the use of temperature integration. However, such a greenhouse...

Spatial variability of xylem sap flow in mature beech (Fagus sylvatica) and its diurnal dynamics in relation to microclimate (2008)

Saveyn, An, Steppe, Kathy, Lemeur, Raoul

The spatial and diurnal variability of sap flow in a mature beech tree (Fagus sylvatica L.) was investigated on days with different climatic conditions (sunny, cloudy, rainy), during the summer. Sap...

Validation of a dynamic stem diameter variation model and the resulting seasonal changes in calibrated parameter values (2008)

Steppe, Kathy, De Pauw, Dirk, Lemeur, Raoul

Validation of ecological models is not a straightforward task and much controversy exists in the published literature on the exact definition. A lot of approaches have been suggested, without one...

A step towards new irrigation scheduling strategies using plant-based measurements and mathematical modelling (2008)

Steppe, Kathy, De Pauw, Dirk, Lemeur, Raoul

Because of the increasing worldwide shortage of freshwater and costs of irrigation, a new plant-based irrigation scheduling method is proposed. In this method, two real-time plant-based measurements...

Stem respiration and carbon dioxide efflux of young Populus deltoides trees in relation to temperature and xylem carbon dioxide concentration (2008)

Saveyn, An, Steppe, Kathy, McGuire, Mary Anne, Lemeur, Raoul, Teskey, Robert O.

Oxidative respiration is strongly temperature driven. However, in woody stems, efflux of CO2 to the atmosphere (E-A), commonly used to estimate the rate of respiration (R-S), and stem temperature...

Growth Response of Hedera helix L. to Temperature Integration (2008)

Pollet, Bruno, Steppe, Kathy, Dambre, P., Van Labeke, Marie-Christine, Lemeur, Raoul

Reducing energy use in greenhouses contributes to the profitability of the horticultural industry. Important energy savings can be realized through the use of temperature integration. However, such a...

Partial rootzone drying of drip irrigated 'Navel' orange trees [Citrus sinensis (L.) Osbeck] under semi-arid tropical conditions (2008)

Dzikiti, S., Steppe, Kathy, Lemeur, Raoul

The diurnal transpiration of 'Navel' orange trees [Citrus sinensis (L.) Osbeck], inferred from sap flow measurements, followed periodic oscillations due to the cyclic opening and closing of stomata...

A novel methodology for irrigation scheduling using plant-based measurements and mathematical modelling (2008)

Steppe, Kathy, Lemeur, Raoul, De Pauw, Dirk

Because water is a scarce resource with often intense competition between different users, the search for an optimal irrigation strategy remains an important research objective. In the present study,...

Short-rotation forestry of birch, maple, poplar and willow in Flanders (Belgium) II. Energy production and CO2 emission reduction potential (2007)

Van Camp, Nancy, Van De Casteele, Liesbet, Verheyen, Kris, Lemeur, Raoul

Belgium, being an EU country, has committed itself to a 7.5% reduction of greenhouse gas emissions during the first commitment period of the Kyoto Protocol. Within this framework, the Flemish...

Short-rotation forestry of birch, maple, poplar and willow in Flanders (Belgium) I - Biomass production after 4 years of tree growth (2007)

Van Camp, Nancy, Van De Casteele, Liesbet, Verheyen, Kris, Lemeur, Raoul

During the last three decades, oil crises, agricultural surpluses and global climate change enhanced the interest in short-rotation forestry (SRF). In this study, the biomass production of birch...

Solutions to overcome pitfalls of two automated systems for direct measurement of greenhouse tomato water uptake (2007)

Vermeulen, Kristof, Steppe, Kathy, Janssen, Katrien, Bleyaert, Peter, Dekock, Jan; U0043107, Aerts, Jean-Marie; U0002494, ...

Two promising techniques to measure water uptake in a direct way were evaluated on substrate-grown truss tomato plants (Lycopersicon esculentum 'Clothilde'). The first technique, which is called the...

Daytime Depression in Tree Stem CO2 Efflux Rates: Is it Caused by Low Stem Turgor Pressure? (2007)

Saveyn, An, Steppe, Kathy, Lemeur, Raoul

Background and Aims Daytime CO2 efflux rates (FCO2) from tree stems are often reported to be lower than expected from the exponential relationship between temperature and respiration. Explanations of...
