“…In most reports that consider root development, stumps and large roots are excavated in time series with individual trees showing remarkably consistent relationship between above and belowground biomass that varies little among taxa and environment (cf Enquist and Niklas 2002). In a smaller number of studies, rooting density has been used to monitor site occupation by forest tree root system (Adegbidi et al 2004;Bouillet et al 2002;Hughes and Gandar 1993;Luxrnoore et al 1993;Misra et al 1998;Narnbiar 1983;O'Grady et al 2005;Zutter et al 1999). As in our work (Figs.…”

“…Temporal responses are equally important to define. For instance, root systems proliferate during forest stand establishment in proportion to plant production (Adegbidi et al 2004;Hughes and Gandar 1993;Misra et al 1998;O'Grady et al 2005), indicating increased root system capacity for nutrient and water acquisition. Defining spatial and temporal variation is essential to determining the relative magnitude of genetic and environmental fictors.…”

Spatial and temporal patterns of root distribution in developing stands of four woody crop species grown with drip irrigation and fertilization

In forest trees, roots mediate such significant carbon fluxes as primary production and soil C 0 2 efflux. Despite the central role of roots in these critical processes, information on root distribution during stand establishment is limited, yet must be described to accurately predict how various forest types, which are growing with a range of resource limitations, might respond to environmental change. This study reports root length density and biomass development in young stands of eastern cottonwood (Populus deltoidies Bartr.) and American sycamore (Platanus occidentalis L.) that have narrow, high resource site requirements, and compares them with sweetgum (Liquidambar styraczj7ua L.) and loblolly pine (Pinus taeda L.), which have more robust site requirements. Fine roots (<1 mm), medium roots (1 to 5 mm) and coarse roots (>5 mm) were sampled to determine spatial distribu-

“…Graciano et al (2006) suggested that fertilisation with P increases N uptake by enhanced growth through a mechanism unrelated to increased N demand. The nitrogen status in E. camaldulensis leaves (10.08 to 20.62 g kg -1 ) was similar to the average concentration of 15 g kg -1 reported in other research for different Eucalyptus species of comparable age (MISRA et al, 1998). This was also similar to the average value of 14 g kg -1 related in another study in which N contents in E. camaldulensis leaves were evaluated 36 months after planting (HUNTER, 2001).…”

-Forestry plantations should be regarded as an alternative sustainable land-use system in degraded savannah areas. They contribute to the maintenance of productive processes in degraded soils that are of economic importance for local inhabitants; in addition, in the ecological sense, timber and non-timber products from planted forests reduce the exploitation pressure on native forests. Eucalyptus plantations on degraded savannahs in the northern Brazilian Amazon may help to reduce exploitation pressure on native forests. However, there is no information regarding the nutrients rates that would allow faster eucalyptus growth in that region. A trial was installed in an Yellow Latosol (Oxisol) soil type adopting a one-half-type fractional factorial design with four rates of N, P, and K. Functions were adjusted for the dependent variables height, diameter at breast height (DBH), leaf tissue nutrient content, and soil-chemical attributes. Interaction N versus K was observed on tree height with a maximum of 7.8 m recorded at 200 kg ha -1 of N and 50 kg ha -1 of K. Phosphorus fertilization promoted greater DBH growth with maximum value at 120 kg ha -1 of P; however, the highest gain was obtained at 30 kg ha -1 of P. The NPK rates that maximized Eucalyptus camaldulensis growth were 200, 30, and 50 kg ha -1 , respectively.

Abstract:We examined the effects of nitrogen and phosphorus fertilizer and paclobutrazol on flowering precocity and abundance in Eucalyptus nitens Deane & Maid. Trials to test these effects consisted of a factorial nitrogen by phosphorus experiment replicated on two sites and factorial nitrogen by paclobutrazol experiments conducted separately on reproductively immature and reproductively mature trees. The increase in tree size due to nitrogen fertilization increased the occurrence and abundance of precocious flower buds. However, the increase in tree size alone could not account for the nitrogen effect on flowering, indicating a secondary mechanism of flower induction by nitrogen. The application of both nitrogen fertilizer and paclobutrazol substantially increased the occurrence of precociously flowering trees over that of either treatment applied alone. The efficacy of both paclobutrazol and nitrogen in stimulating the flowering of the reproductively mature trees was affected by soil type, but this effect was overcome through the combination of nitrogen and paclobutrazol. The combination of nitrogen and paclobutrazol also restricted tree growth and combined applications on nitrogen deficient sites will be beneficial in commercial systems for producing eucalypt seed.
