Gestão de resíduos sólidos no município de Tibagi - PR: desempenho da coleta seletiva

The objective of this study was to analyze the performance of solid waste management in the municipality of Tibagi, Paraná, a city with approximately 20000 inhabitants, which implemented the selective collection program called Recycle Tibagi. The analysis was based on descriptive statistical techniques, considering the three types of waste (tailings, organic and recyclable), and per capita generation of garbage upward trend in the coming years, based on the method of Winter (Triple Exponential Damping), using data recorded by the Department of the Environment and the Association of Recyclable Materials from Tibagi - ACAMARTI. Efficient selective collection from a structured environmental education program with constant training conducted with the scavengers, possible to obtain important data in sorting and marketing of recyclable materials, saving raw materials, water and energy, as well as relevant indicators social inclusion and employment generation and income. The project involves several areas of municipal management and arouses curiosity and interest in several areas: social, financial, environmental and administrative. It's a way to encourage new projects and public bodies, highlighting the importance of recycling and proper disposal of solid waste.

Andropogon grass consortium with stylo in two times: the forage response and sources of phosphorus rates

The use of legumes intercropped with forage in the Brazilian savannah (Cerrado) region is an alternative to reverse the process of pasture degradation. The natural phosphorus deficiency in this region and the high retention capacity of this nutrient in the soil are factors that directly affect the sustainability of the production system. The objective of this study was to evaluate the effect of a phosphate with medium solubility (Arad) compared to more soluble sources such as triple superphosphate and mono-ammonium phosphate, on the formation and maintenance of pastures of Andropogon gayanus with or without the introduction of Stylosantes guianensis in pasture already established in the Brazilian savannah. Two experiments were carried out under field conditions in an Oxisol using a randomized block design with split plots, plots with two sources of phosphorus (Arad and super-triple or MAP) and subplots with different levels of phosphorus. The study showed that andropogon grass, even though characterised as forage requiring low fertilization, responded to increased fertilization, especially with the use of more soluble sources of P at planting. From the second year on, with the introduction of Stylosantes guianensis, verified effects were seen on legumes in their efficiency of utilization of residual fertilization from the first year; however, this didn't affect legume dry matter production resulting from the P sources used for the andropogon grass. The mixed stands of andropogon grass and Stylosantes guianensis made it more advantageous to increase the P sources using phosphate fertilizer with lower solubility (Arad), when compared to MAP.

Crescimento e produção do maracujazeiro amarelo, sob diferentes fontes e doses de fósforo em cobertura

Brazil is the largest world producer of yellow passion fruit, a fruit crop which is exigent in nutrients, although little studied in relation to phosphorus fertilizing, fundamental on plant establishment. An experiment was carried out during the period of March/2010 to April/2011 in Remigio County, Paraiba State, Brazil, in order to evaluate the vegetative and productive attributes of yellow passion fruit plants under different sources and doses of phosphorus. Treatments were distributed in randomized blocks in tree replications and twelve plants by plot using the factorial design 2 x 5 referring the sources of superphosphate triple and superphosphate simple at levels P2O5 of 0, 12, 18, 24 and 30 g cave(-1). The following variables were recorded: stem diameter, number of productive branches, number of fruits per plant, fruit mass and fruit yield. The sources and doses of phosphorus affected growth and fruit production of yellow passion plants. The triple superphosphate is the most phosphorus efficient source for growth and fruit production of yellow passion fruit. The triple superphosphate dose which promoted the maximum yield of yellow passion fruit is 42.86 g.
