| Sumario: | The substrate of seedbeds is crucial for obtaining quality seedlings in any type of cultivation. The high cost of imported substrates requires the use of stable, proven quality, and safe local materials, by-products from the agro-industry. The physical properties of substrates are critical and difficult to modify once in the container. The objective of this work was to analyze the physical properties of three substrates: sand, sheep wool, and siliconized cotton for lettuce seedlings. Sand showed lower total porosity, air porosity, and water retention capacity compared to the other treatments. Siliconized cotton exhibited physical properties similar to sheep wool. The use of local, biodegradable, and economical substrates such as sheep wool promotes sustainability and a circular economy by utilizing sheep by-products. Producers prioritize the cost-benefit ratio and market availability when selecting a substrate. |
