The two agricultural practices that can lead to algal blooms are:
1. **Application of nutrients to crops** - The use of fertilizers can result in nutrient runoff, particularly nitrogen and phosphorus, which can contribute to algal blooms in waterways.
2. **Animal waste accumulated in livestock production** - The waste produced by livestock can contain high levels of nutrients, which, when washed into water bodies, can also promote algal blooms.
Erosion caused by livestock overgrazing, withdrawals of water for crop irrigation, and sediments released by tilling of soil, while they can have various environmental impacts, are not directly linked to the phenomenon of algal blooms as strongly as the two practices mentioned above.
