Establishment of Anadenanthera colubrina var. cebil under mycorrhizal inoculati...
Simão Soares, Márcia Toffani; Fernandes, Fernando Antonio; Curcio, Gustavo Ribas; Menezes, Gustavo; de Resende, Alexander Silva; Gaiad, SérgioThis study aimed to evaluate the establishment of Anadenanthera colubrina (Vell.) Brenan var. cebil [Griseb.] Altschul inoculated with mycorrhizal fungi and fertilized in the Pantanal of Nhecolândia, Mato Grosso do Sul State, Brazil. The experiment was established in March 2015 in a deforested “cordilheira” environment, in randomized blocks distributed in micro-relief, with subdivided plots. The main treatments...
Chemical properties of soil treated with waste from the pulp and paper industries
Maeda, Shizuo; Bognola, Itamar AntonioThe 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 cell...
Influence of lime and phosphorus in initial growth of eucalyptus and in P criti...
Maeda, Shizuo; Bognola, Itamar AntonioThe effect of combined application of lime and phosphorus in critical levels in soil and plants of Eucalyptus dunnii in vessels was studied. The treatments consisted of three levels of lime (C0, without liming; C1/2, liming with half the doses to raise the pH in water at pH 5.5 by the method of SMP; C1, liming with dose to raise the pH in water at 5.5 by the same method) and five doses of phosphorus (0, 50, 150...
Evaluation of Seedlings Gowth of Eucalyptus badjensis in Substrata from Compost...
Maeda, Shizuo; Andrade, Guilherme de Castro; Ferreira, Carlos Alberto; Silva, Helton Damin da; Agostini, Raul BortolottoThe 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 alka...
Effect of liming, Gafsa rock phosphate and triple superphosphate in early growt...
Maeda, Shizuo; Bognola, Itamar AntonioThe effect of combined application of lime, phosphorus sources and forms of application of the phosphorus sources on growth and P uptake of Eucalyptus dunnii have been studied in pots. The treatments consisted of two levels of liming (C0, C1 lime to raise to pH 5.5 in water by pH SMP method), two phosphorus sources (triple superphosphate and Gafsa rock phosphate) and two forms of application of phosphorus sourc...
Response of Pinus taeda to ash from plant biomass in Cambissolo Humico in pots
Maeda, Shizuo; Silva, Helton Damin da; Cardoso, CamileThe 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 ...
Biometric characteristics and seedlings nutrition of Pinus taeda under salinity...
Maeda, Shizuo; Silva, Helton Damin da; Bellote, Antonio Francisco JuradoThe 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 t...
Characterization of Substrates Elaborated with Organic Residues to Produce Fore...
Maeda, Shizuo; Dedecek, Renato Antonio; Agostini, Raul Bortolotto; Andrade, Guilherme de Castro; Silva, Helton Damin daConsidering the need for viable options for destination of waste from agricultural and agriindustries activities waste from logging and brewing industries and goat dregs previously composted, with potential foruse as substrates for the production of seedlings of trees were characterized chemically and physically. The treatments had consisted of the following mixtures: S1) commercial product for substratum (Plan...
Changes in chemical characteristics of a Litholic Humic Neosol grown with Pinus...
Maeda, Shizuo; Silva, Helton Damin da; Bellote, Antonio Francisco JuradoThe 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 m...
