“…In spite of that in Australia, about one third of the P. radiata plantations with commercial interest (more than 150 000 ha) have been planted in areas receiving less than 800 mm of annual rainfall (Boomsma and Hunter, 1990). For instance in south Australia the species can produce very high yields even at rainfalls lower that 750 mm (Boardman, 1988). The lack of climatic sensitivity that we have found in our Mediterranean plots suggest that in good soil fertility conditions P. radiata can grow well even at moderately low rainfall regimes (750-950 mm).…”

“…The species has also been grown commercially in areas with as little as 600 mm of annual rainfall. For example, in south Australia with a Mediterranean-type climate, silvicultural treatments (fertilization, thinning, use of herbicides and pesticides, genetic selection) have achieved high productivities and sustained growth where the mean annual rainfall slightly exceeds 600 mm even without irrigation treatments (Boardman, 1988). The Spanish foresters from the Mediterranean area sometimes refer to radiata pine as the ''dry land poplar'' because it can give yields almost as high as Populus sp.…”

“…Soil nutrient status, which is strongly linked to parent material (Turner and Lambert, 1986), is a significant determinant of growth in Australia (Boardman 1988), Chile (Toro and Gessel, 1999), New Zealand (Ross et al, 2009;Watt et al, 2010) and South Africa (Zwolinski et al, 2002). Overall major nutrient deficiencies in these countries include nitrogen, phosphorus, boron and zinc and less frequently magnesium, potassium, calcium, sulfur, manganese and copper (Mead, 2013).…”

H.E. Bown, and M.S. Watt. 2016. Stem and soil CO 2 efflux responses of Pinus radiata plantations to temperature, season, age, time (day/night) and fertilization. Cien. Inv. Agr. 43(1):95-109. Stem CO 2 efflux is a highly variable component of the carbon budget of forest ecosystems. It reflects the balance between the CO 2 respired by the living stem tissues, less the CO 2 dissolved in the xylem sap moving upward in the transpiration stream, plus the CO 2 transported from the roots and released at the stem. Although knowledge about such fluxes at different spatial and temporal scales has markedly increased, knowledge of the effects of silviculture treatments, such as fertilization, on stem CO 2 effluxes are still limited, particularly when connecting above-and belowground processes. Using measurements obtained from twin plots (one control, one fertilized) installed in five-, 12-and 23-year-old stands of Pinus radiata, the objective of this study was to examine the influence of the temperature, stand age, fertilization, season and time of measurement (day/night) on the stem CO 2 efflux, soil CO 2 efflux and their ratio. There was a strong significant positive relationship between the stem CO 2 efflux and temperature. The slope between these two variables declined as the stand age increased and was higher for nighttime than daytime measurements. The stem CO 2 efflux was higher in the fertilized plots compared with the unfertilized (control) plots for the 5-and 12-but not the 23-year-old age classes. In contrast, the soil CO 2 efflux was largely unaffected by the temperature, time of measurement (day/night), fertilization and stand age; however, significantly higher values of soil CO 2 efflux were measured during spring than during the other seasons. Given the relative invariance of the soil CO 2 efflux to the temperature and treatment effects, the ratio of the stem:soil CO 2 effluxes was affected by the same factors as the stem CO 2 effluxes. These results suggest that fertilization would increase wood production and wood CO 2 efflux without changing the soil CO 2 efflux, thus most likely proportionally increasing aboveground C partitioning and decrease belowground C partitioning, with this effect being enhanced at younger ages.
