Which sustainability practice can improve soil health?

Composting is a sustainability practice that plays a significant role in improving soil health. This process involves the decomposition of organic materials, such as food scraps and yard waste, into nutrient-rich compost that can be added to soil. The addition of compost helps enhance soil structure, improve water retention, and increase microbial activity, which is vital for healthy plant growth. By providing essential nutrients and fostering a balanced ecosystem in the soil, composting not only benefits individual plants but also supports overall land health.

The other options, while relevant in waste management, do not offer the same benefits for soil health. Landfilling typically leads to the accumulation of waste without the natural breakdown and enrichment of soil. Recycling focuses on reprocessing materials but does not directly contribute to soil enhancement. Incineration, while reducing waste volume, can lead to the loss of nutrient-rich organic materials that could otherwise enrich the soil. Thus, composting stands out as the most effective method for enhancing soil health among the given choices.
