[en] In order to allow recycling with byproducts arising from the extraction of cellulose, in a sustainable manner for the natural world, the objective of this study was to test the effectiveness of an organic compound formed with these wastes, the recovery of a degraded soil from the planting of tree species Mabea fistulifera Mart. and Eucalyptus urograndis. The experiment was carried in 2010, February out at the Teaching and Research Farm, Ilha Solteira Campus (UNESP), located in Selvíria-MS. The experimental design was used split plots in blocks, with layout on track, with 6 treatments and 4 replications. The 2 treatments in main plots were represented by plantations of Eucalyptus urograndis hybrid (Eucalyptus - exotic species) and Mabea fistulifera (locally called "Canudo-de-pito" – a native species). Subplots were tested doses of the compound and also the comparison with mineral water supply, with 6 treatments (SI - area without intervention; D0 - without fertilization; DAM - mineral fertilizer according to crop need; D10 - composted manure according the crop needs (10 Mg ha-1 of compost); D15 and D20 (15 and 20 Mg ha-1 of compost, respectively). Were analyzed in the laboratory soil physical, chemical and biological attributes, the development of tree species, the contribution monthly litter and returning nutrients to the soil. Results were analyzed by performing the analysis of variance single correlation Scott-Knott test for comparison of means and the regression analysis between the doses. Were detected improvements in infiltration of ground water and soil penetration resistance. The highest values of nutrients were observed at a dose of 20 Mg ha-1, however, there was a sharp increase in pH. The most important development of the planted trees was in the area where the mineral fertilization was performed and the dose of 10 Mg ha-1 was the most promising in their development. Inputs of nutrients, litter and epigeal fauna activity increased significantly.

[gl] Baseado na idea de reciclar os subprodutos de extracción de celulosa dun xeito sostible para a natureza, o obxectivo deste estudo foi avaliar a eficacia dun composto orgánico, obtido a partir destes residuos, na recuperación de un solo degradado no que se plantaron dúas especies de árbores: Mabea fistulifera Mart. e Eucalyptus urograndis. Realizouse un estudo de campo na "Fazenda de Ensino e Pesquisa, Campus de Ilha Solteira" (UNESP), situada no municipio de Selvíria-MS, Brasil. O delineamento experimental foi en bloques aleatorios e subdivididos, seguindo un esquema en faixa, con seis tratamentoss e catro repeticións. Os dous tratamentos das parcelas principais incluíron plantacións do híbrido Eucalipto urograndis (unha especie exótica de eucalipto) e Mabea fistulifera (especie nativa). Nas subparcelas foron probadas diferentes doses de compost, que tamén foron comparadas con fertilizante mineral. Os seis tratamentos estudados foron os seguintes: SI, área testemuña, sen intervención; D0 sen adubo; DAM, adubo mineral segundo o prescrito para a especie cultivada; D0, D15 e D20 adubado con compost utilizando doses de 10, 15 e 20 Mg ha-1, respectivamente. Foron analizadas no campo ou no laboratorio algunhas propiedades físicas, químicas e biolóxicas do solo; tamén se estudou o desenvolvemento das especies arbóreas e a achega mensual de follas e outros productos forestais ao solo. Os resultados foron analizados a través da análise de varianza, a correlación lineal, a proba de Scott-Knott para comparación de medias e a análise de regresión entre as doses. Detectáronse melloras na infiltración de auga do solo e a resistencia á penetración tras a utilización de compost. Os valores máis elevados de nutrientes no solo foron observados para o tratamento con 20 Mg ha-1 de compost, no que tamén se detectou un aumento acentuado no valor do pH. O maior desenvolvemento das plantacións, nembargantes, tivo lugar nas parcelas con fertilización mineral, mentres que nos tratamentos con compost a dose de 10 Mg ha-1 mostrouse máis eficiente. O aporte de follaxe, nutrientes e a actividade da fauna epígea aumentaron significativamente coa dose de compost.
