Abstract
The aim of this work was to evaluate the possibility of using different composts from horticultural residues under forced ventilation conditions and different levels of inoculation of microorganisms.
All compost treatments started with a similar volumetric ratio: 2 parts of pepper : 1 cucumber : 1 runner beans : 1 wooden material (sawdust and industrial shavings). Several inoculation methods were evaluated with controlled humidity and using forced ventilation and turn over.
The evaluation trials were: germination assays, growth test and yield using watercress and lettuce, melon, and tomato cherry respectively.
We conclude that these composts can be utilised not only as compost amendment but as horticultural and environmentally friendly substrates.
Also they are able to substitute for other traditional substrates such as peat.
