Abstract: the experiment was carried out in pots using three clayish soils from the municipality of piracicaba, sp, brazil. the objective of this work was to obtain information on the decay of organic residue (corn culture trash applied at the proportion of 50 ton/ha) and the influence of nitrogen sulphate at the levels of 0, 50, 100 and 150 kg n/ha on the added organic material rate of de cay. the experiment was installed at room conditions and protected from rain. the evaluation of the decay was made by determinations of the carbon content and of the c/n ratio of the soils during the incubation period (70 days). the samples were collected and analyzed weekly. the moisture of the soils was mantained at the level of 70% of the water retained at 1/3 atm. the main conclusions are as follows: 1) the addition of mineral nitrogen in the soils accelerated the losses of carbon from the soils, showing a greater effect during the initial incubation period. 2) the addition of nitrogen affected the content of residual carbon in the final incubation period. increasing levels of added nitrogen lowered the remaining carbon content in the soil at the end of the incubation period. 3) the addition of nitrogen affected the reaction of the c/n ratios in all the used soil. the treatments that received mineral nitrogen showed closer c/n ratios during the incubation period. the amount of mineral nitrogen applied was related to the narrowing speed of the values in the initial incubation period. 4) there is a strong indication that little increments of the total nitrogen (with peaks at the 28th day) are related to the addition of mineral nitrogen in all the soils. 5) the evolution of the carbon content and of the c/n ratios can be taken as parameters in the evaluation of the organic material rates of decay for the used soils and within an incubation period of 70 days.

Abstract: Se caracterizó la comunidad de acridomorfos (Orthoptera) a través del análisis faunístico y se determinó el tama o ideal de muestras, en dos áreas del municipio de S o Sepé, RS - Brasil. Los ejemplares fueron obtenidos con el auxilio de una red de recolección, siendo recorridas distancias de 5, 10, 15, 20 y 25 m, a fin de verificar cuál sería la mejor distancia para la colecta de acridomorfos. Las recolecciones fueron realizadas entre enero y mayo de 2009. El cálculo de diversidad fue evaluado a través de los índices de dominancia de Simpson, diversidad de Shannon-Wiener, riqueza de Margalef y equidad de Pielou. Los datos fueron analizados mediante un test no paramétrico de distribución libre chi-cuadrado. El material recolectado representó, 947 acrídidos y 20 proscópidos distribuidos en dos superfamilias,12 géneros y 23 especies. Las especies que presentaron índices elevados de dominio, abundancia, frecuencia y constancia fueron para el área A: Dichroplus silveiraguidoi, Notopomala glaucipes y Scotussa cliens, todas pertenecientes a la familia Acrididae. Para el área B, ocho especies presentaron índices significativos Aleuas vitticollis, Amblytropidia sola, Dichroplus conspersus y Dichroplus silveiraguidoi de la familia Acrididae. El mejor tama o de muestra en términos de precisión estadística fue para 5 m de distancia recorrida. A partir de 25 m se obtuvo el mayor número de individuos y diversidad de especies, pero presentó una elevada desviación estándar y variación. De esta manera, ambos tama os pueden ser recomendados para la obtención de acridomorfos, dependiendo del objetivo del estudio. The research aimed to characterize the community of Acridomorphs through faunal analysis, and to determine the ideal sample size for studies with this group, in two areas from municipality of S o Sepé, RS, Brazil. The specimens were collected by sweep netting, travelling distances of 5, 10, 15, 20 and 25 m, in order to determine which would be the best distance for collecting of acridomorphs. The collections were done between January and May 2009. The calculation of the values of diversity indexes was assessed using the Simpson dominance (D), Shannon-Wiener diversity (H), Margalef richness, and equitability (J’). Data were analyzed by a nonparametric free distribution chi-square test. The collected material represented 947 acridid and 20 proscopids distributed in two superfamilies, 12 genera and 23 species. The species that had high levels of significance in area A were: Dichroplus silveiraguidoi, Notopomala glaucipes and, Scotussa cliens, all Acrididae. In area

Abstract: Em geral, o gerenciamento do lixo urbano vem sendo realizado de forma precária pelas administra es municipais brasileiras.Porém, segundo o IBGE, vem se verificando uma forte tendência de melhora na situa o de destina o final do lixo coletado nopaís nos últimos anos. A gera o de resíduos depende de vários fatores tais como nível cultural, hábito de consumo, renda, clima,sexo e idade da popula o e a sua redu o está atrelada a um programa de gerenciamento com base em três aspectos: redu o nafonte, reutiliza o e reciclagem. O presente trabalho tem como objetivo principal a implanta o de um programa de coleta seletivaem todo o quadro urbano da cidade de Irati (PR) através da Associa o de Catadores do Município. A proposta de implanta o dacoleta seletiva foi dividida em duas etapas: logística e educa o ambiental, ambas já sendo cumpridas. Nos doze primeiros mesesde programa, os resultados mostraram um aumento considerável no volume de material coletado desde o início do programa,atingindo 11,5% do material gerado na cidade proporcionando emprego fixo e renda para 24 catadores de papéis que até ent otrabalhavam informalmente nas ruas da cidade. Com base no total arrecadado ao longo desses 12 meses iniciais, conclui-se que aeconomia pode chegar a 420 mil reais, caso todo o material arrecadado seja utilizado como matéria prima na fabrica o de novosmateriais. Abstract In general, the management of the municipalsolid waste is being carried through a precarious way by theBrazilian municipal administrations. However, according tothe IBGE, it’s being verified a strong improvement trend inthe final destination of the garbage collected in the countrylast years. The generation of wastes depends on some factorssuch as cultural level, consumption habits, income, climate,sex and age of the population and its reduction is related to amanagement program based on three aspects: reduction inthe source, reusing and recycling. This present work focuson implantation of a selective collecting program in theurban area of Irati city (PR) through the CollectorsAssociation. The proposal of implantation of the selectivecollecting was divided in two stages: logistics andenvironmental education, both already being fulfilled. In thetwelve first months of the program, the results had shown aconsiderable increasing in the volume of material collectedsince the beginning of the program reaching 11.5% of thematerial generated in the city providing fixed job andincome for 24 collectors who had been so far workedinformally in the streets of the city.

Abstract: The beneficial effects of the fertilization with silicon have been researched in several species, among them the sugarcane. The objective of this work was to evaluate the influence of silicate on the micronutrients of sugarcane leaves. The experiment was carried out in greenhouse conditions, using a Red-Yellow Argissoil and the calcium and magnesium silicate waste as silicon source. The experimental design used was the completely randomized one, in factorial outline (5x2) with five silicate doses (0; 2.5; 5.0; 10.0 and 15.0 g pot-1) and two cultivars of sugarcane (RB72454 and SP791011), with four replications. After ninety days of budding emission, the cut of the plants was made for analysis of micronutrients (Zn, Cu, Fe and Mn) and silicon (Si) concentrations in the leaves. The varieties presented distinct behavior in relation to the absorption of diverse nutrients. It was observed increase in the Si leaf concentrations, while Fe leaf concentrations decreased with the application of silicate into the soil. The RB72454 variety accumulates more Si compared to the SP791011 variety.

Abstract: The experiment was installed in greenhouse, using one of the most representative soils of the state of Ceará, Brazil, for sugarcane crop, a Red-Yellow Argissoil. The main goal of this research was to evaluate the influence of silicon in the gas exchange and production of biomass of sugarcane cultivars in sandy loam soil. It was used a completely randomized in 5x2 factorial scheme with five silicon doses: 0; 2.5; 5.0; 10.0 and 15.0 g per pot-1 of siderurgical slag, two cultivars of sugarcane and four repetitions. The siderurgical slag (calcium and magnesium silicato) used containing 11% of soluble SiO2. It was evaluated the silicon level in the leaf, the production of dry matter of the aerial part, the relative growth rate of the plant, the water use efficiency, transpiration and conductance of the leaf. The results showed increase in concentration of Si in leaf with the application of the silicon; practically no influence in growth and physiological characteristics of the plants.Key-words: Argissoil, calcium, greenhouse, sugarcane.
