“…Therefore, it is possible that nutrients were not largely limiting growth, and that the fertilization had a less extreme effect than if applied to a nutrient-limited site [63]. This is in line with Paavilainen [13], who also encountered a weak response to fertilization of birch on a fertile site.…”

This study investigates wood density and anatomy of juvenile silver birch stems in Sweden, grown in mixed conifer stands. Our aim is to investigate if fertilization provides increased growth, as well as an eventual reduction in stem wood density. Measurements of basic density, ring width, cell wall thickness, and vessels are analyzed for 20 birch trees. Bark to pith radial sections are analyzed using a light microscope and the freeware ImageJ to compare treatments and ages. The results show that trees with fertilizer treatment have wider growth rings and thinner cell wall thickness compared to unfertilized trees. The fertilized trees also have a lower cambium age at the same height and the same diameter, and a slightly lower stem mean density (420 kg m−3) than the unfertilized stems (460 kg m−3). Fertilizer is a significant determinant of density and cell wall thickness in nonlinear models. The fertilized trees have increased growth and reached a fixed diameter earlier. The age difference between the trees likely explains some of the differences in cell wall thickness. This study supports the use of fertilizer as a silvicultural option for increasing the growth rate of silver birch for a relatively small reduction of wood density.

“…Previously published information about the response of birch to fertilization is inconsistent. Paavilainen [13] remarked that birch usually has a positive response to fertilization, but it was smaller than the response of conifers. Hoyle and Bjorkbom [14] also reported an increase in birch growth after fertilization.…”

& Key message Fertilization is a feasible management technique for Pinus pinea L. cropping, with increased cone production up to 9 years after the application and superior trunk diameter growth every year. Fertilization effects on cone size-weight indicate the value of re-fertilizing. & Context Stone pine (Pinus pinea) is a species of economic interest for its highly in demand pine nuts. Despite the high value of pine nuts, cones are harvested mostly from non-managed forests. Consequently, advances in cropping techniques, such as fertilization, are needed. & Aims To monitor the effect of fertilization on growth and cone production during 10 years after fertilization, adjusted to soil characteristics, on a 16-year-old stone pine orchard. & Methods A fertilization trial including fertilized and non-fertilized plots was established. Diameter (trunk and crown) and height were repeatedly measured in each tree for 10 years. Cones were annually harvested from each tree and counted. & Results Stone pine cone production increased significantly from the third to the ninth year of treatment, with a peak increase of 3.3 times. & Conclusion Fertilization was a useful silvicultural practice to increase stone pine cone production. Periodical fertilization is recommended.
