“…The concentrations of P and K were positively related to growth and were significantly lower in former forest areas, as expected from the results of previous studies (Laroche et al 1997). The plantations in this study displayed lower foliar concentrations of P and K, similar values for Ca and Mg and much higher foliar N than other chestnut stands with different structures and management (coppice stands, orchards), in other regions of Spain and Portugal (Santa Regina 2000;Pires et al 1995).…”

The growth and nutritional status of 97 hybrid chestnut plantations on former agricultural land and forest land were studied in relation to site conditions (climatic variables and soil properties). A single family of curves was obtained for classifying the early height growth of hybrid and sweet chestnut. Soil limitations and nutrient deficiencies were evident in the former forest land, whereas the agricultural soils were found to be generally suitable for growing chestnut. The stands with highest growth rates were characterized by high foliar concentrations of K, P and Ca. Successful growth of the plantations was always related to high summer precipitation, low elevation and absence of long periods of risk of frost. The results confirm the adaptability of chestnut to most sites where it has been planted for timber production.

“…In fact, it is claimed that the binding capacity of calcium cations can strengthen the middle lamellas, as described by the "egg-box model" developed by Grant et al [37]. Several studies have been performed to clarify the relationship between calcium contents in the soil and in trees, with a special regard to ring shake incidence [33,34,49,50,59,63,66,67]. The results obtained indicate a link between very low calcium contents and ring shake incidence, yet without providing the evidence for a direct relationship between them.…”

-Too often chestnut wood (Castanea sativa Mill.) becomes economically uninteresting because of the high risk of ring shake to which this species is prone. For more than twenty years chestnut ring shake has been the subject of studies undertaken in an effort to understand its underlying causes and mechanisms. Since not all aspects of the phenomenon have been sufficiently studied at the present time, ring shake has not yet been completely elucidated. However, it is possible to outline a general framework of the phenomenon and advance preliminary ideas on the causes that contribute to the development of this type of fracture. This article summarises the current state of knowledge, discusses the possible causes and proposes measures to reduce the risk of ring shake occurrence in chestnut.ring shake / Castanea sativa Mill. / wood / residual stresses / mechanical strength Résumé -La roulure du châtaignier (Castanea sativa Mill.): connaissances actuelles. Trop souvent le bois de châtaignier (Castanea sativa Mill.) perd son intérêt économique à cause du haut risque de roulure qui affecte cette espèce. Depuis plus de vingt ans la roulure du châtaignier fait l'objet de plusieurs études vouées à la compréhension des causes et des mécanismes qui conduisent à sa formation. À l'état actuel tous les aspects n'ont pas été suffisamment étudiés pour que l'on puisse considérer la roulure comme un phénomène complè-tement élucidé. Malgré cela, un cadre général du phénomène peut être esquissé et des premières réflexions sur les causes qui mènent à l'apparition de ce type de fracture peuvent être avancées. Cet article résume l'état des connaissances acquises à ce jour, discute les causes possibles et propose des mesures afin de diminuer le risque d'apparition de la roulure chez le châtaignier. roulure / Castanea sativa Mill. / bois / contraintes résiduelles / résistance mécanique Ann.

“…Consequently, as far as we know, there are no field studies on NPK fertilization. However, studies done with young potted plants have shown that the crop responds to the application of mineral nutrients (El Kohen et al, 1992;Laroche et al, 1997), and therefore it is expected that a positive response to fertilization may also occur in the field. Pérez-Cruzado et al (2011) used wood-bark ash, a product rich in Ca, K, Mg, and to a lesser extent P, as a fertilizer in a young chestnut orchard.…”

European chestnut is the most important cash crop in the highlands of NE Portugal. However, limited data on cropping technique are available to help farmers make decisions. This work is motivated by the lack of data related to chestnut response to fertilizer application. It reports results from a field fertilization trial consisting of the application of a combination of lime (L), nitrogen (N), phosphorus (P), potassium (K), and boron (B), namely LNPKB, NPKB, -NPKB, N-PKB, NP-KB, and NPK-B. Seedlings of chestnut were planted in June 2013 and grown for four growing seasons. Plant height, trunk diameter, and pruning wood were assessed every year and used as indicators of tree crop growth. Elemental leaf analysis and other tools [SPAD-502 chlorophyll meter; Field Scout CM 1000 NDVI (normalized difference vegetation index) meter, and the OS-30p+ fluorometer] were used to assess plant nutritional stresses. In January 2017 soil samples were collected at three depths (0-5, 5-10, and 10-20 cm) to determine several soil fertility parameters. The nonapplication of K and B reduced the tree crop growth and pruning residues. Leaf analysis revealed leaf K and B concentrations respectively in the NP-KB and NPK-B treatments to be in the deficient range previously established for chestnut. SPAD readings and NDVI detected the reduced availability of N associated with the -NPKB treatment but not the reduced plant growth associated with NP-KB or NPK-B treatments. The dark adaptation protocols of F V /F M , F V /F 0 , and OJIP measurements performed with the OS-30p+ fluorometer failed to diagnose the nutrient stresses detected by leaf analysis or the reduction in plant growth.
