“…In South Sumatra, the application of 36 kg P ha −1 early in the rotation at seven sites planted to E. pellita resulted in a 38%-198% increase in stand volume at age 3 y [26]; the application of a range of P rates at planting at ten sites planted to A. mangium resulted in a 40%-180% increase in stand volume at age 1 y [8]. In A. mangium, site responsiveness is linked to a range of soil characteristics and particularly the physical characteristics of subsoil [27]. Ferreira and Stape [28] have also linked responses to fertiliser application by tropical E. urophylla in south-eastern Brazil to soil type.…”

Eucalyptus pellita has rapidly emerged as the species that has replaced Acacia mangium in broad-scale commercial plantations in Indonesia following widespread losses due to disease and in soils that have suffered a steady decline in phosphorus (P) under plantation forestry. Conversion from a nitrogen (N)-fixing to a non-N fixing species is expected to change the nutrient dynamics and the management required to maximise productivity. In this study in South Sumatra, responses of E. pellita to the application of N, P, potassium (K) and calcium (Ca) fertilisers were assessed at a number of trials on sites with varying site history; A. mangium was planted at one site to compare the species' responses to N and P. The growth of E. pellita responded significantly (p < 0.01) to P's application but not to N, K or Ca, with the addition of P increasing the stem volume by 32.6 m 3 ha −1 at 3 years of age compared with no addition of P fertiliser; the demand for P in the first two years of growth was, respectively, 4.8 and 6.8 kg ha −1 . This positive and large response appears to be because E. pellita has a lower efficiency in its use of P than A. mangium and is, therefore, more responsive than A. mangium to the addition of P. The reason for the lack of response to N remains unclear, although demand for N as well as K and Ca was high. These results suggest that sites recently converted to E. pellita from A. mangium and also new ex-native forest sites will be likely to only respond to P addition and that the response of E. pellita is likely to be greater than for A. mangium to maximise yield. At present, additional N, Ca or K fertilisers are not required, but this may change in the future.

Yogyakarta, Indonesia 55281Jln. PT TEL Rambang Dangku, Muara Enim, Indonesia 31172 -Fertilization is one of the nutrient management efforts that play an important role in improving the productivity of plantation forests. It was conducted to provide adequate nutrients for the plant at the initial growth period when the availability of soil nutrients is very limited. The optimum dose of fertilization for each plant is different depending on its requirement, climate, and soil properties. This study investigated the influence of fertilization on early growth, aboveground biomass, carbon storage, and leaf characteristics in Eucalyptus pellita in the sixth months after field establishment. An experiment comprising four treatments of fertilization, i.e., 0, 75, 133, and 167 kg ha of triple superphosphate 46% P O was set up using randomized complete block design with five replications. Four indicators were selected to evaluate the early growth of E. pellita, namely survival rate, height, the collar of diameter, and crown projection area. Aboveground biomass and carbon storage of E. pellita were estimated in each component, covering stem, bark, branches, and leaves. The leaf characteristics of E. pellita described by individual leaf area, individual leaf dry weight, specific leaf area, and leaf area index Results showed that the different treatment of fertilization did not have a meaningful effect on survival rate, individual leaf area, and specific leaf area. The treatments presented a substantial effect on other indicators such as height, diameter, crown projection area, aboveground biomass, carbon storage, individual leaf dry weight, and leaf area index. Despite the fact that the highest mean of height and collar of diameter were observed in the dose of 167 kg ha , the greatest average of aboveground biomass and carbon storage were noted in the rate of 133 kg ha . Nevertheless, this study did not find a highly different performance of E. pellita between both treatments statistically.-1 2 5were .-1 -1

“…The soils of the plantation areas in South Sumatra are ultisols, described as highly weathered with many chemical and physical constraints (Nurudin et al 2013). Despite these constraints, not only was the productivity of the acacia plantations high, there was also no apparent response to any fertiliser except P at the two sites where this was tested.…”

Tropical plantations are an important source of forest products both to meet the growing demand for wood, and to facilitate the transition from native forests to more sustainably produced forest resources. Management of these plantations for optimal productivity and resource-use efficiency is vitally important, and nutrient management is a critical component of sustainable plantation production. In this study, we explored the response of Acacia mangium plantations in South Sumatra, Indonesia, to fertiliser and their requirement for fertiliser, focusing on phosphorus (P) at establishment. Almost all plantations across a series of 11 sites were highly responsive to P fertiliser, with nine of the 11 sites having more than double the productivity in P-fertilised treatments at age 1 year compared with control treatments. However, the quantity of P required for 90% of maximum growth was generally low by age 2 or 3 years, and 10 kg P ha -1 at establishment was sufficient to ensure that at least 90% of maximum growth was captured across all the experimental sites. At a 12 th site, we explored the interactions between genotype and weed control, and found that both effects were additive in the response of the plantations to P, and thus there was no substitutability between management types: weed control, genotype and P needed to be managed in combination to achieve maximum productivity.
