Mudanças nos atributos quím icos do solo e crescimento de um povoamento de Eucalyptus Grandis fertilizado com composto de resíduos da indústria de celulose e papel

Abstract

The purpose of this study was to investigate the effect of compost on soil and plant of an compostamended soil under Eucalyptus grandis for one years; from may 2006 to may 2007. Thus, it was evaluated the soil fertility, nutritional status and growth of a Eucalyptus grandis plantation fertilized with compost. The trial was established at the Farm Francos of Guararema-(São Paulo State, Brazil). The experimental design was in complete randomized blocks, with 4 replicates. There were eight treatments, namely: (1) control; (2) mineral fertilization; (3) 15 t ha-1 compost with 100% dregs; (4) 15 t ha-1 compost with 50% dregs; (5) 15 t ha-1 compost from aeration passive; (6) 15 t ha-1 compost and inoculation with microorganism; (7) 15 t ha-1 compost with slugdes primary and inoculation with microorganism and (8) 15 t ha-1 compost and mineral fertilization. The applications the compost 360 treatment resulted in a higher soil Na content and value the PST and C.E. The tratament with mineral fertilization and mineral fertilization more compost proportion higher growth plant.
