The two agricultural practices that can lead to algal blooms are:
1. **Animal waste accumulated in livestock production** - This waste can contain high levels of nutrients, particularly nitrogen and phosphorus, which can run off into nearby water bodies and contribute to algal blooms.
2. **Application of nutrients to crops** - The application of fertilizers, especially those rich in nitrogen and phosphorus, can lead to nutrient runoff into water bodies, promoting algal growth.
These practices introduce excess nutrients into aquatic ecosystems, which can trigger harmful algal blooms.
