Valorização de resíduos orgânicos na formulação de substratos alternativos à turfa para a produção de plantas aromáticas envasadas em modo de produção biológico
| Resumo: | The objective of this work was to evaluate the performance of two coconut coir and one compost (based on forestry wastes and horse manure), as components of peat-free substrates for the organic production (OP) of potted herbs. Seven different species of herbs were grown in seven peat-free substrates (based on coir and compost), one peat based substrate certified for OP (control) and two peat based substrate certified for OP with an extra fertilization. One of the tested coconut coir was phyto-toxic, with a Munoo-Liisa Vitality index of 9%, produced small plants with a poor root system. In all seven species, plants growth in the mixtures of non-phytotoxic coir and compost was equal or higher than the growth in control, showing that these peat-free mixtures are a viable alternative, cheaper than commercial substrates. Extra fertilization tended to increase plants growth, showing the need to optimize fertilization. Coconut fiber and compost can be successfully used as substrate components for organic production of potted herbs, once phytotoxicity is evaluated and fertilization optimized |
