The present work evaluated the use of sewage sludge compost as a substrate component for Eucalyptus urophylla x E. grandis seedling production. Doses of sewage sludge compost and rice hulls were established with the following proportions (%): 100/0, 80/20, 60/40, 50/50, 40/60 and 20/80, and they were compared to commercial substrate commonly used in the nursery. Higher growth rates were observed on seedlings grown on substrates containing sewage sludge than on those containing commercial substrate.
The use of sewage sludge compost in the substrate at levels above 40% is favorable to Eucalyptus urophylla x E. grandis seedlings growth. Use of sewage sludge compost as a substrate for seedling production is a viable way to its disposal.
