Abstract

DyDOC identifies three soil horizons with different properties. Within each horizon the transport of wter, metabolic transformations of organic matter, and sorption of potential DOC are simulated. The model is parameterised by fitting experimental laboratory and field data, including 14C signals. The outputs are quasi-steady state C pools, varying on long timescales (centuries) and daily DOC concentrations and fluxes.

Abstract

Fuktforandringer i trelasten etter tørking før den når frem til sin endelige bruk er studert. En dynamisk modell for fuktutvikling i stabilt klima er utviklet og analysert. Temperaturområdet er 3 - 60 gr C, og modellen gjelder for planker av 50 mm gran. Arbeidet inngår i bestrebelene for å finne frem til en mer generell modell for et reelt, vekslende klima.

Abstract

An intensive field planting of `Edda", "Opal" and "Mallard" plum trees (Prunus domestica L.) all grafted on the semidwarf rootstock St. Julien A was established in 1993 at Ullensvang Research Centre, western Norway at 60 ° North. The objectives were to evaluate four different single row planting systems (vertical axis, free spindle, hedgerow and Y-trellis) and three planting densities ( 0.5, 1.0, 1.5 x 4 m for the Y-trellis and hedge trees and 2.0 x 4 m for the central leader trees) in a northern climate. These planting distances give a range of tree density of 1250 - 5000 trees per ha. The experiment gave a small yield in the third leaf on all canopy systems. During the first four cropping years, the yields/ha were positively correlated with tree density. Cumulative yield per hectare was highest on the Y-trellis and hedge trees with the highest density (5000 trees per ha). In the fourth leaf, the Y-trellis trees gave 15 tons per hectare. No differences in fruit size or the soluble solids content among canopies or densities were found.
