Abstract

The solid waste of recycling paper industry has potential to be used for the correction of soil acidity and as a source of nutrients for agricultural crops and forestry. This work aimed to evaluate the effects of different doses of recycled paper sludge and top fertilization on the availability of macronutrients in Eucalyptus saligna Smith, based on a test with seedlings with three months old transplanted to pots distributed with spacing an experimental area. After homogenization of particle size and moisture content of the sludge, was implemented a completely randomized design with two factors (dose and top fertilization), and three repetitions, totaling eighteen samples of leaves and roots for each micronutrient. The recycled paper sludge did not affect the availability of P. Also, did not was a source of N, K, and Mg for plants. The residue was a source of Ca for the vegetal development.

Keywords: Forestry; agro-industrial residues; sustainability.
