“…This result stands in strong contrast to other studies (e.g. Smethurst et al 2003). L varied in response to fertilizer application in the study of Smethurst et al (2003) whereas in the current study it was assumed that L was most heavily influenced by water availability owing to similar land-use history and establishment practices among sites, including fertilizer application.…”

“…Smethurst et al 2003). L varied in response to fertilizer application in the study of Smethurst et al (2003) whereas in the current study it was assumed that L was most heavily influenced by water availability owing to similar land-use history and establishment practices among sites, including fertilizer application. The lack of relation between L and water availability found here is similar to that found by Battaglia et al (1998) who, although concluding that L was related to an index of water stress and to temperature, found a great deal of scatter in both relations.…”

“…The orthogonal test results showed that the nine treatments all promoted the growth of Ginkgo, and Treatment 7 (N: 400 g•tree −1 , P: 200 g•tree −1 , K: 90 g•tree −1 ) was the most effective one. The response to fertilization in Ginkgo plantations depended on the degree of mismatch between nutrient supply from the soil and the plant nutrient demand [32]. With an increment in the N fertilizer, there was also an increment in the growth, foliar nutrient status, and photosynthesis rate of the Ginkgo plantation.…”

Ginkgo biloba L. is one of the most extensively planted and productive commercial species in temperate areas around the world, but slow-growth is the most limiting factor for its utilization. Fertilization is one of the key technologies for high quality and high forest yield. To better understand the impacts of fertilization on Ginkgo productivity, the effects of fertilization treatments (single fertilizer and combined fertilizer) on growth, nutrient content in Ginkgo leaves, and photosynthesis characteristics were studied in a 10-year-old Ginkgo plantation over two years. The single factor experiments suggested that DBH (diameter at breast height), H (height), NSL (length of new shoots), and V (trunk volume) showed significant differences between the different levels of single nitrogen (N) or phosphate (P) fertilizer application. Orthogonal test results showed that the nine treatments all promoted the growth of Ginkgo, and the formula (N: 400 g·tree −1 , P: 200 g·tree −1 , potassium (K): 90 g·tree −1 ) was the most effective. G s (stomatal conductance) and P n (net photosynthesis rate) showed significant differences between the different amounts of single N or P fertilizer application, while single K fertilizer only affected P n . Combined N, P, and K fertilizer had significant promoting effects on C i (intercellular CO 2 concentration), G s and P n . N and P contents in Ginkgo leaves showed significant differences between the different amounts of a single N fertilizer application. A single P fertilizer only improved foliar P contents in Ginkgo leaves. A single K fertilizer application improved N and K content in Ginkgo leaves. The effects of different N, P, and K fertilizer treatments on the nutrient content of Ginkgo leaves were different.

“…Albaugh et al [35] found much larger gains, an increase of 101% in the LAI, in response to fertilization in loblolly pine. In Eucalyptus nitens plantations, nitrogen fertilization increased the LAI by up to 3.1 units, i.e., 56% increment [36].…”

Fertilization increases productivity in Eucalyptus plantations, but losses in productivity associated with soil fertility continue at operational scales. In this study, we evaluated the fertilization response (FR), light use efficiency (LUE) and growth efficiency (GE), i.e., the amount of wood biomass accumulated per unit of light absorbed (LUE) and per unit of leaf area index of Eucalyptus plantations. We used a "twin plot" approach, with 161 blocks representing 52,700 ha of planted forests that spanned a broad range of edaphoclimatic conditions in southeastern Brazil. The normal plots (NP) were part of a permanent inventory network, whereas the twin plots (TP) received extra high levels of fertilization and extra weed control after fertilization. The intensive management (twin plots) led to a large increase of 5.3 Mg¨ha´1¨year´1 of wood increment. The region without dry periods and with soils with high clay content was most responsive to fertilization, with a 15% increment in the LUE and 10% increase in the GE of the TPs compared with those of the NPs. Our results suggested that water availability was the primary element affecting productivity and potential response to fertilization. With this information, decisions can be made on which regions should receive priority fertilization investments. However, more research is required to determine the most limiting nutrient in each type of environment.
