| This study aimed to evaluate the spatial and temporal variability of chemical attributes of a Red Oxisoil due to the application of lime and potassium chloride in variable rate through the use of thematic maps. The study was conducted in the municipality of Terra Roxa, Paraná State, Brazil, in farm of 41.68 hectares, in which two samples were taken, the first held in 2010, prior to the application of the products, and the second in 2013. In each sampling chemical attributes were measured: pH in CaCl2 0.01 mol L-1, potassium (K), base saturation (V%) and the participation of K in the exchange complex (%K). For realization of geo-referenced mapping, the property was divided into grids of three acres, by collecting soil samples in the depth 0-20 cm. From... |

| The uncontrolled generation of organic waste causes the decrease of the life of landfills. Alternative treatment processes such as anaerobic digestion of organic wastes may be a viable alternative to disposal of such organic waste, and the use of this technology can still generate gains using biofertilizer in agriculture. Thus, the present study aimed to evaluate the anaerobic digestion of Ceasa vegetables wastes from Cascavel-PR by adding swine manure doses (inoculum) in order to reduce the volume of waste going to landfills. Alternative 12 digesters were developed, and are added 29 liters of effluent (fruit and vegetable wastes) in each reactor, by adding inoculum 3 levels: 0, 1, 2, 3 liters (pig manure). During 50 days of digestion were analyzed the... |
