Renkaankasvatus

Renkaankasvatus, often translated as "tire cultivation" or "tire farming," is an agricultural practice that utilizes discarded tires as a growing medium or as structural elements in garden beds. The primary concept involves filling old tires with soil and planting seeds or seedlings within them. This method is particularly popular in areas with limited arable land or for home gardeners seeking to repurpose waste materials.

The advantages of renkaankasvatus include its low cost, as tires are readily available and often free. Tires can also help retain soil moisture and warmth, potentially leading to faster plant growth, especially in cooler climates. Their raised nature can also improve drainage and make gardening more accessible for individuals with mobility issues. Furthermore, it offers an environmentally friendly way to dispose of used tires, diverting them from landfills.

However, concerns have been raised regarding the potential leaching of chemicals from the rubber into the soil, which could affect plant health and food safety. Some studies suggest that certain compounds in tires might be harmful, although the extent of this risk is still debated and depends on factors like tire age, type, and environmental conditions. Despite these concerns, many practitioners report successful and healthy crop yields, particularly for non-edible plants or when using tires for decorative purposes.
