“…Notwithstanding, application of the recommended sludge dose alone resulted in a wood volume approximately 99% of that using mineral NPK fertilizers (Table 6), due to soil fertility improvement. The contents (surface A p horizon) of total N, organic C, resin extractable P, K, Ca and Mg, and DTPA extractable and semi-total Cu, Fe, Mn and Zn in the soil increased as a function of sludge application dose, besides leaf litter, for up to 44 months of sludge application (Maldonado, 2009). Under these conditions, nutrient and water uptake and use by Eucalyptus plants are more efficient (Bouillet et al, 2002;Silva et al, 2013;Stape et al, 2006).…”

“…High forest wood production depends, in addition to water and nutrient availability, on the maintenance of the tree canopy's ability to intercept a high proportion of solar radiation (Forrester, 2013;Gonçalves et al, 2004). The increase in Eucalyptus wood production as a function of sludge dose was also related to leaf area index (LAI) and the amount of litter on the soil surface (Firme, 2009;Maldonado, 2009), as they are indicative parameters of forest production quality. We have observed that the higher the sludge dose, the higher the LAI, amount of litter and both N and P accumulation in shoots of the Eucalyptus plants (paper in process).…”

Fertilization of Eucalyptus plantations using sewage sludge on unfertile tropical soils represents an alternative to using mineral N and P fertilizers. A 44-month field experiment was conducted to study the effects of increasing application of sludge, and its interactions with mineral N and P fertilizers, on wood volume. Four rates of sludge (0, 8, 15 and 23 Mg ha, dry base), N (0, 47, 95 and 142 kg ha) and P (0, 28, 56 and 84 kg ha of PO) were combined in a 4 × 4 × 4 factorial scheme in a totally randomized block design. Response surface and age-shift modeling was used to establish an initial recommendation for mineral fertilization of the Eucalyptus plantations treated with sludge and to analyze the implications of increased growth on the duration of the forest cycle in a tropical climate. The results showed that from 8 to 44 months after planting, the sludge application (with or without N and P) yielded a statistically larger wood volume (P < 0.05), compared to application of N and P fertilizers only. The response surface modeling showed the following outcomes: i) application of sludge based on N criterion reduced the need for N and P fertilizers by 100%; and ii) an increase in wood volume by 7% could be achieved, compared to NPK fertilizers only, if 2/3 of the recommended P was applied. The cultivation time to produce 150 m ha of wood volume was 45 months for the control and was reduced by two, three, four, or five months, respectively, through application of recommended P, sludge dose, sludge plus one third of P, and sludge plus two thirds of P. On the whole, sewage sludge could represent an excellent unconventional N and P fertilizer source for wood production on unfertile tropical soils.

“…Esta tendência vem ocorrendo porque estes resíduos industriais estão sendo produzidos com menos contaminantes devido às mudanças no processo de fabricação (Harrison, et al, 2003). Vários estudos têm mostrado que o dregs, cinza e o lodo de esgoto, quando aplicados de forma isolada, trazem benefícios agronômicos às culturas -relacionados ao aumento e, ou, manutenção dos níveis de fertilidade do soloem função do fornecimento de nutrientes ou por meio de alterações em seus atributos químicos (Guerrini, et al, 2000;Harrison, et al, 2003;Rocha, et al, 2004;Corrêa et al, 2007;Lira, et al, 2008;Maldonado, 2009). Por outro lado são poucos os estudos para avaliar os benefícios agronômicos do composto orgânico produzido a partir da mistura dos resíduos gerados no processo de produção de celulose e papel.…”

The purpose of this study was to investigate the effect of compost on soil and plant of an compostamended soil under Eucalyptus grandis for one years; from may 2006 to may 2007. Thus, it was evaluated the soil fertility, nutritional status and growth of a Eucalyptus grandis plantation fertilized with compost. The trial was established at the Farm Francos of Guararema-(São Paulo State, Brazil). The experimental design was in complete randomized blocks, with 4 replicates. There were eight treatments, namely: (1) control; (2) mineral fertilization; (3) 15 t ha-1 compost with 100% dregs; (4) 15 t ha-1 compost with 50% dregs; (5) 15 t ha-1 compost from aeration passive; (6) 15 t ha-1 compost and inoculation with microorganism; (7) 15 t ha-1 compost with slugdes primary and inoculation with microorganism and (8) 15 t ha-1 compost and mineral fertilization. The applications the compost 360 treatment resulted in a higher soil Na content and value the PST and C.E. The tratament with mineral fertilization and mineral fertilization more compost proportion higher growth plant.

“…Também observou-se efeito significativo (p ≤ 0,10) de LE e de fósforo sobre o volume de madeira com casca para este experimento aos 43 e 44 meses pós plantio de Eucalyptus grandis respectivamente (FIRME, 2009;MALDONADO, 2009). Assim, nota-se que a tendência de respostas da produção de madeira manteve o efeito para a fertilização mineral fosfatada e à aplicação de LE.…”

The sewage sludge (SS) applied in planted forest soils, based on the nitrogen criterion, may increase the production of wood without causing damage to the forest environment. However, there is a need for research to evaluate the use of nutrients contained in the SS and to recommend appropriate management regarding for its application on soil using mineral fertilizer supplements by aspects of productivity and economic. The objective were to analyze the effect of combinations of sewage sludge doses and nitrogen and phosphate mineral fertilizer on the production on dry matter content and wood production of Eucalyptus grandis at 95 months after planting, and to evaluate the economic viability of SS recommendation and its complementation with nitrogen and phosphate mineral fertilizer for the forest producer. The experiment was installed in a commercial area of Suzano, in Angatuba-SP, sludge doses are applying (0, 7.7, 15.4 and 23.1 Mg ha-1 , dry base), and nitrogen mineral fertilizer (0; 46.9; 95.1 and 142 kg ha-1), phosphate (0, 27.7, 55.9 and 84 kg-1 P 2 O 5), and potassium (175 kg ha-1 K 2 O for all treatments, due to the low content of this nutrient in SS); in a randomized block design in a factorial 4x4x4. For the specific purpose of this study, combinations were taken in doses of N and P and among all these SS doses were studied. The production of dry matter and wood, calculated by equation Smalian were determined from measurements collected at 95 months post-planting eucalyptus. The revenue and cost values were raised in the reference year 2013. For the evaluation of the economic viability, we used the method of annualized net present value (ANPV), considering 6 and 12% per year discount rates and that the forest producer would bear 0 or 100% of the cost of transport of sewage sludge. There was a linear effect of SS doses on the production of dry biomass of wood, bark, leaf and branches and wood volume. The dose of 23.1 Mg ha-1 SS, equivalent to 150% of SS dose recommended by the criterion nitrogen, provided the highest total dry matter, 187 Mg ha-1 , and wood+bark of 173 Mg ha-1 and stem volume of 529 m 3 ha-1 , with average annual increment of 66 m 3 ha-1 yr-1. When considering the criterion to the application of SS, based on N, and the forestry producer has borne all the shipping cost of this waste, it was observed that the highest economic return treatment was that using a dose of 15.4 Mg ha-1 SS and 84 kg ha-1 P 2 O 5 to 6% per year discount rate; and one that applied 7.7 Mg ha-1 SS and 28 kg ha-1 P 2 O 5 to the interest discount rate to 12% per year rate. When the forest producer was exempted to pay the SS shipping cost, the most economically viable treatment was what used 15.4 Mg ha-1 doses of SS and 84 kg ha-1 P 2 O 5 to 6 and 12% per year discount rates.
