The two agricultural practices that can lead to algal blooms are:
1. **Application of nutrients to crops** - The use of fertilizers can introduce excess nutrients, particularly nitrogen and phosphorus, into water systems, promoting algal growth.
2. **Animal waste accumulated in livestock production** - Manure can also contribute significant amounts of nutrients to water systems, leading to the same problem of nutrient enrichment and resultant algal blooms.
So the correct answers are:
- application of nutrients to crops
- animal waste accumulated in livestock production
