| O efeito da aplicação combinada de calagem, fontes de fósforo e forma de aplicação das fontes no crescimento e absorção de fósforo em mudas de Eucalyptus dunnii foi estudado em condições de vaso. O experimento foi conduzido em casa-de-vegetação não climatizada, utilizando um Cambissolo Húmico Ta Alumínico Típico, durante 67 dias. Os tratamentos consistiram na combinação de dois níveis de calagem (C0, sem calagem e C1, dose para elevar o pH em água a 5,5 pelo método do pH SMP), duas fontes de fósforo (superfosfato triplo e fosfato natural de Gafsa) e dois modos de aplicação das fontes de fósforo (incorporada e localizada). A calagem aumentou a produção de matéria seca da parte aérea, o crescimento das mudas, o acúmulo e a eficiência de uso do P no... |

| The application of cellulosic waste in forest plantations is an alternative to disposal, but more studies are necessary to confirm the safity of this disposal. The response of Pinus taeda L. to salinity in Humic Distrocryept was evaluated. In plantation, the seedlings were assessed for their height and stem diameter (SD), and at 120 days, were assessed the SD, height, dried root biomass (DRB), shoot (DBS) and total dried matter (TDM). The contents of P, K, Ca, Mg and Na were determinated, and, based on these levels it was estimated the quantity of these elements and calculated the efficiency use in leaves and roots and translocation to the shoot. Except the relationship between DSB/DRB, the other variables were significantly influenced by increased... |

| The aim of this work was to evaluate, in vase, the effect of cellulosic residue in soil and chemical characteristics of effluents resulting from that application in Litholic Humic Neosol layers collected in the 0 to 10 and 10 cm to 30 cm. Doses of sludge, equivalent to 0, 10, 20, 40 and 80 Mg ha-1 were implanted in a randomized design. Aliquots corresponding to doses of sludge, collected on the treatment were mixed to the soil layer of 0 to 10 cm and placed in vessels after the completion of the soil layer from 10 cm to 30 cm. At 117 days after implantation of the test, samples were collected from the soil layer from 0 to 20 cm and from the effluent resulting from the application of water for irrigation. The treatments changed the characteristics... |

| The aim of this work was to evaluate the seedling growth of Eucalyptus badjensis Beuzev. & Welch in substrata prepared from different residues: pulp and paper mill wastes (organic sludge and cellulose mill liquid alkaline liquor), brewery malt and also goat manure. The experiment was carried out in the seedlings nursery of the Embrapa Florestas, in Colombo, Paraná. The organic sludge, cellulose mill liquid alkaline liquor and the brewer’s grain were previously composted with sawdust, and goat dung with pinus bark. A randomized blocks design with split-plot arrangement, with four replications was used. Plot treatments were the substrata and split-plot were base fertilization (with and without): 1) mixture of a commercial substratum prepared with... |

| The use of wastes generated in the pulp and paper industries as an input to agricultural and forestry is an alternative to the disposal problem, and contribute to reducing the cost of agricultural and forestry production. However, for proper and safe use of this waste, it is necessary to know its effects on soil chemical properties. The effect of doses of calcium carbonate, ash forest biomass, lime mud and cellulosic sludge in chemical attributes of a Dystrophic humic Entisol. The pH, exchangeable Ca, Mg and P increased with increasing doses, while the Al content and its saturation were reduced with the application of doses of all tested materials. The K levels increased mainly by wood ash. The Ca/Mg ratio was increased by the application of calcium... |

| The aim of this work was to measure the effect of ash, collected from the boiler of a pulp mill and applied in doses equivalent to 0, 10, 20, 40 and 80 t.ha-1 on the chemical characteristics of the soil and on the development and absorption of nutrients for Pinus taeda L. seedling potted with CAMBISSOLO Humico from the 0-20 cm layer in Piraí do Sul, PR. Portions of the soil were placed in pots and aliquots of each treatment were applied to the first 0-10 cm layer after filled the pots with 20 cm of soil. Needles and soil (0-10, 10-20 and 20-30 cm layers) were analyzed. The height, diameter and dried biomass of aerial part, the root - MSR and total were evaluated. The application of ash reduced the acidity and the concentration of Al, and increased the... |
