Name a practice that can improve soil fertility.

Adding organic amendments, such as compost or manure, is an effective practice for improving soil fertility. Organic amendments enhance the soil's structure, increase its ability to retain moisture, and provide a diverse array of nutrients necessary for plant growth. These materials not only supply nutrients but also improve microbial activity and overall soil health, creating a more favorable environment for plants.

Compost and manure contribute organic matter to the soil, which promotes the growth of beneficial microorganisms that play a vital role in nutrient cycling. This process helps to release nutrients in a form that plants can absorb, thereby enhancing soil fertility over time. Moreover, incorporating organic matter can lead to improved soil aeration and drainage, which further supports healthy root development.

In contrast, while chemical fertilizers can provide quick nutrient boosts, excessive reliance on them can lead to nutrient imbalances and degrade soil health in the long term. Planting cover crops is also beneficial for soil fertility, as they prevent erosion and can enhance the nutrient content of the soil, but they are a more indirect method compared to the immediate benefits of adding organic amendments. Regularly applying pesticides does not enhance soil fertility and may even harm beneficial soil organisms.
