The two agricultural practices that can lead to algal blooms are:
1. **Application of nutrients to crops** - Excessive use of fertilizers can result in nutrient runoff, particularly nitrogen and phosphorus, into water bodies, which often leads to algal blooms.
2. **Animal waste accumulated in livestock production** - The runoff from areas where livestock waste is concentrated can contribute high levels of nutrients to nearby water sources, promoting algal growth.
These practices introduce excess nutrients to aquatic ecosystems, creating conditions that are favorable for algal blooms.
