    Efeito da adubação com cama de aviário na cultura do milho para silagem e nos parâmetros microbiológicos do solo

    With crescent increase in brazilian chicken production, also remarkable the increase in poultry litter production appearing in this way, the need for a management and appropriate destination for this residue. The poultry litter use as a nutrient source for agriculture, including the maize, it is a valuable and promising alternative. The present research had the ambit to study maize productivity for silage as to: Dry Mass production [MS], Crude Protein [PB], Ether Extract [EE], Mineral matter [MM] and Organic Matter [MO] and microbiological soil properties, Microbial Biomass Carbon [CBM] and Metabolic Quotient [qCO2] and the relation CBM/ Total Organic Carbon [COT], in a Rhodic Eutrudox with mineral fertilizer (33 Kg N, 80 Kg P2O5 e 80 Kg K2O) and poultry litter (wood shavings and rice straw) with the treatments 2,5; 5,0; 7,5 e 10,0 Mg ha-1 in consortium oats/maize grown under no-till on crop 2012/2013. The treatments with poultry litter received, at the sowing time, 1/3 mineral fertilizer. The soil sampling were performed in the layer 0 – 10 cm in the inter row at times different (1) oats, (2) after liming, (3) poultry litter after application (4) after herbicide, (5) after corn planting, (6) vegetative phase and (7) reproductive phase. the CBM and qCO2 values were influenced by anthropogenic activity in all treatments, highlighting the CBM fall and significant increase in quotient metabolic in the treatment with mineral fertilizers. The treatments that received poultry litter, the relation CBM/COT demonstrates greater efficiency in the carbon use, no significant changes between rice straw and wood shavings. For the MS production, there was no difference between treatments and nutrient sources, featured the treatments 7,5 PA and 10 MAR that showed the highest levels of protein and ether extract, similar the treatment with mineral fertilizers. Concluded that treatments with poultry litter favored the soil organic matter use, causing less microbiological activity disturbance and that the wood shavings and rice straw poultry litter can replace 2/3 of fertilization lossless or decrease production and corn silage characteristic.

    (Universidade Estadual do Norte do Paraná, 2014-02-26) Zapparoli, Rafael Aguiar; Reis, Luiz Carlos; https://orcid.org/0000-0003-2193-8535; http://lattes.cnpq.br/4310404758664835; Abi-Saab, Otávio Jorge Grígoli; https://orcid.org/0000-0002-1757-636X; http://lattes.cnpq.br/8437035647330384; Tashima, Hatiro; https://orcid.org/0009-0008-8757-4600; http://lattes.cnpq.br/0514640010249563; Reis, Teresinha Esteves da Silveira; https://orcid.org/0000-0001-6379-4790; http://lattes.cnpq.br/5705088234641018; Rodrigues, Euripedes Bomfim; https://orcid.org/0000-0001-6531-878X; http://lattes.cnpq.br/9720688699522760
    The objective to evaluate the production of dry matter , crude protein and the chemical and physical soil for different levels of fertilization of pelleted poultry litter attributes . The test was conducted at the experimental farm of the University of North Paraná State - Campus Luiz Meneghel ( UENP / CLM ), the Bandeirantes - Paraná , the predominant soil in the area is the Oxisoil . The experimental design was randomized blocks , contained in five treatments with 0 , 5 , 10 , 15 and 20 Mg ha- 1 year-1- of pelleted poultry litter, with four replications , totaling 20 plots . Data were subjected to analysis of variance and regression parameters for the production of dry matter ( Mg ha- 1) and crude protein content . The physical and chemical soil variables was analyzed by Tukey test at 5% probability. The soil chemistry parameters was assessed levels of organic matter , potassium, phosphorus, calcium and magnesium from the soil and the soil physical attributes parameters evaluated were soil density, macro, micro, total porosity, percentage of aggregates and mechanical resistance soil penetration . The results showed: the of pelleted poultry litter can be considered an important source of nutrients to the grassy studied providing the increased production of dry matter, content of organic matter, exchangeable K and influence on soil aggregation.
