Defoliating Insect Mass Outbreak Affects Soil N Fluxes and Tree N Nutrition in Scots Pine Forests
Biotic stress by mass outbreaks of defoliating pest insects does not only affect tree performance by reducing its photosynthetic capacity, but also changes N cycling in the soil of forest ecosystems. However, how insect induced defoliation affects soil N fluxes and, in turn, tree N nutrition is not well-studied. In the present study, we quantified N input and output fluxes via dry matter input,...
متن کاملEffects of timing of soil frost thawing on Scots pine.
Effects of the timing of soil thawing in the spring on Scots pine (Pinus sylvestris L.) were studied under controlled laboratory conditions. Sixteen 6-year-old saplings were lifted from the field, replanted in containers and placed in four treatments in controlled environment (CE) chambers with four replicate saplings per chamber. The saplings were held in the CE chambers during one simulated w...
متن کاملFungal communities in fallow soil before and after amending with pine sawdust
Pine sawdust (9 kg m−2) was ploughed into soils, intended for future forestry plantations, that had been left for 3 or 6 years after previously being used for agriculture. Two years after the amendment, soil pH had changed in both sites and the C:N ratio had increased. Total fungal populations decreased after the treatment. A small decrease in the number of species was not statistically signifi...

متن کاملInfluence of wood ash on soil chemical composition and biochemical parameters of young Scots pine
Short-term effects of different doses (0.25 and 0.5 kg m) of wood ash fertilization in a field experiment in a 20-year-old Scots pine stand on a nutrient-poor sandy soil (Arenosol) was studied in North Estonia. Soil chemical properties, nutrient accumulation, soluble carbohydrates, starch, hemicellulose, cellulose, and lignin were used as biochemical indicators for the assessment of the state o...
