Which method is commonly used to restore nutrients to the soil in deforested areas?

Restoring nutrients to the soil in deforested areas can be achieved through practices that enhance soil quality and promote ecosystem health. One commonly utilized method is the practice of adding organic materials, such as compost or mulch, which can include biomass from burned vegetation. Controlled burning can facilitate the recycling of nutrients back into the soil by breaking down organic matter, making nutrients more available for future plant growth. However, it is essential that this practice is managed carefully to avoid negative impacts such as soil erosion or loss of biodiversity.

Other methods mentioned, such as using chemical fertilizers, can provide temporary nutrient boosts but may lead to long-term soil degradation and water pollution if overused. Growing non-native species can disrupt local ecosystems and affect native biodiversity. Increasing agricultural practices may not necessarily restore nutrients and can often lead to further soil degradation if not done sustainably. Therefore, the method that focuses on natural cycles and enhances soil fertility through organic matter, like burning vegetation followed by careful management, is a valid approach to nutrient restoration in deforested areas.
