Initial analysis of the Eucalyptus super clone fertilized with swine wastewater sludge

Abstract

The generation of waste has gradually increased due to the large swine production and with this comes the concern about the final destination of the product. This study aimed to analyze the initial behavior of Eucalyptus super clone (AEC 1528), fertilized with swine sludge and compared to chemical fertilizer. The experiment was conducted in a completely randomized design with 5 treatments and 3 replications, with the volumes: 1.25, 2.5, 5 liters; 0 liters of sewage sludge and chemical fertilizer. The plants were irrigated with water from a well at the Rio Verde University, increasing the amount according to plant growth. After 120 days, we evaluated the height of the plants, stem diameter, relation between stem diameterand plantsheight, weight of the fresh matter, weight of the dry matter,root weight, leaf areaand mortality. There were significant differences in relation to plant height, the fresh matterweightand the dry matterweight. For the other characteristics there was no negative influence with the use of  different volumes of sewage sludge in eucalypts hybrid. It was observedthat, the application of biosolids (sludge from swine) is an effective alternative fertilizer in eucalyptus plantations.
