The two agricultural practices that can lead to algal blooms are:
1. **Application of nutrients to crops** - The use of fertilizers, particularly those high in nitrogen and phosphorus, can result in nutrient runoff into water bodies, promoting the growth of algal blooms.
2. **Animal waste accumulated in livestock production** - Animal waste can be a significant source of nutrients, particularly nitrogen and phosphorus, which can also runoff into water bodies and stimulate algal growth.
The other options (sediments released by tilling of the soil, withdrawals of water for crop irrigation, and erosion caused by livestock overgrazing) are less directly associated with algal blooms than the two identified above.
