Resumo(s)
The present work aimed to study the possible use of "crushed bricks" (a waste from
the bricks manufacturing) as a substrate component for the production of potted herbs in
organic farming (OF).
Two main substrate components were used: compost (obtained from forestry
residues and horse manure) and a mixture of coir and compost (1:1 by volume). Each of
these “main” substrate components was mixed with "crushed bricks" in the following
proportions by volume: 0%, 5%, 10% and 20%. As a control, a commercial substrate was
used. A total of 9 different substrates were studied. The substrates properties and the growth
of 4 different species of herbs (coriander, parsley, rosemary and lavender) on those
substrates were evaluated.
Crushed bricks significantly affected the physical properties of the media, increasing
the bulk density and the water retention, but reducing the porosity and the aeration. The
addition of 5% crushed bricks proved to be beneficial for the production of aromatic potted
plants, because the positive effect on the physical properties of the substrate resulted in an
improvement of some plant’s growth parameters, mainly when the main component of the
substrate was compost.
