“…The most common method of fertilization carried out in NW Spain, as well as in other parts of the world [53], consists of a single application of NPK type fertilizer at establishment. The dose usually used is approximately 100 g of NPK type fertilizer per plant, i.e.…”

Nutrition and growth in newly established plantations of Eucalyptus globulus in northwestern Spain

-The growth and nutritional status of newly established Eucalyptus globulus plantations, located in NW Spain, were studied in relation to soil properties and site preparation techniques. Most of the plantations are growing on chemically poorly fertile soils of intermediate depth. Despite being fertilized at establishment, most of the plantations showed low foliar levels of P and Ca, and some showed deficiencies of Mg and K. Growth depended mainly on the altitude, length of the drought period and on concentrations of Ca in soils. Productivity is reflected by the concentrations of Ca in leaves. Preparation of the soil by windrowing reduced levels of Ca, Mg and P in the soil, negatively affecting nutrition and growth and causing an increase in tree mortality. The results suggest subsoiling to be the most suitable site preparation technique for shallow soils, and also indicate the need for repeated fertilization and the adoption of silviculture management practices that enhance the natural turnover of nutrients.Eucalyptus globulus / forest nutrition / forest soils / silviculture / forest growth Résumé -Nutrition et croissance dans les nouvelles plantations d'Eucalyptus globulus du nord ouest de l'Espagne. La croissance et l'état nutritionnel des plantations d'Eucalyptus globulus du nord-ouest de l'Espagne ont été étudiés en fonction des caractéristiques édaphiques et des techniques de préparation du site. La plupart des plantations sont installées sur des sols pauvres de profondeur moyenne. Bien que fertilisées à la plantation, la plupart des plantations révèlent des concentrations foliaires limites en P et Ca, et certaines révèlent des carences en Mg et K. La croissance dépend principalement de l'altitude, de la durée de la période sèche et aussi de la concentration de Ca au sol. La concentration de Ca en feuilles est très représentative de la croissance. L'extraction de litière et les rémanents d'exploitation lors de la préparation du site, réduisent la teneur en Ca, Mg et P du sol, affectant de manière négative la nutrition et la croissance, et aboutissant à une hausse de la mortalité. Ces résultats suggèrent l'idoneité du subsolage comme méthode de préparation du site, la nécessité de fertiliser plusieurs fois et d'adopter une sylviculture qui favorise le renouvellement naturel des nutriments.Eucalyptus globulus / nutrition forestière / sols forestiers / silviculture / croissance forestière

“…The relationships between plant canopy nutrient content and soil chemical nutrients is important as benchmarks for assessment of plants' ability to respond to fertilizer treatments, and associated optimum growth returns (Schönau and Herbert ,1989). In this study, significant (p<0.05) correlations were obtained between soil carbon and canopy spectra, i.e.…”

“…Furthermore, these wavelength regions are associated with organic matter absorption features, and by extension, to soil carbon as one of the key derivatives/indicators of decomposing organic materials. Overall, the success illustrated in this study and other related studies in estimating soil fertility properties from canopy spectral features, e.g., Aitkenhead-Peterson et al 2006, Albrechtová et al 2008, and Mzinyane et al (2015, should not be ignored, given the interrelationships that exist between the amount of nutrients in the soil and their impacts on vegetation health and associated expression in canopy-level foliar spectral measurements (Schönau and Herbert 1989). Such research efforts provide scientists with innovative research methods, given the ever-improving imaging spectroscopy sensors which are envisaged to provide better and enhanced soil property mapping and modelling approaches than previously imagined (JPL, 2010).…”

Effects of management techniques on the establishment of eucalypt seedlings on farmland: a review

2009

View full text Add to dashboard Cite

Research into the effects of seven management techniques on survival and growth of eucalypt seedlings planted on farmland is reviewed. The techniques include: pre-and post-planting weed control; soil cultivation; fertiliser; mulch; tree guards/ shelters; and irrigation. The initial and ongoing effects of each technique are discussed-including the effects of timing, type and quantity. Consideration is given to site, species and climatic influences. A statistical analysis of the published survival rates is then presented, to provide information on the relative importance of, and interactions between, practices. The analysis shows that maximum survival may be achieved by using one or two management techniques. Combining this result with the insights gained from the review suggests that the use of soil cultivation and post-planting weed control are likely to achieve the greatest improvements in early eucalypt survival and growth.
