Abstract

Considering the increasing application of horticultural substrates and the fact that soil is still used
by producers in their mixes, it was conduced an experiment aiming to verify the viability of a Haplumbrept soil as a
component of horticultural substrate mixes, along with organic conditioners. The soil was chosen due to their high
total porosity, high level of organic matter and low capacity to agricultural use. In the experiment, the soil was
mixed, in volumetric proportion 1:1, with water hyacinth [Eichhornia crassipes (Mart.) Solms], rest of sugar cane,
sawdust of Pinus sp and carbonized rice hulls. The mixes were submitted to physical (bulk density, total porosity,
water availability and aeration) and chemical characterization (pH and total soluble salt concentration). Except to
the mix with sawdust, all mixes improved physical characteristics, providing lower bulk density, higher porosity and
more water availability. All conditioners, but water hyacinth, increased the mixes pH, and all of then increased
soluble salts contents.
