The preparation of the substrate is of fundamental importance for obtaining quality seedlings. Due to the scarcity of natural resources, there is a growing demand for alternative materials to be used for the cultivation of seedlings and plants. These materials should be easy to obtain, environmentally correct, have a stable structure, reasonable decomposition time, be homogeneous, low cost, and contain physical, chemical, and biological characteristics compatible with the seedling to be produced.
