Soil conservation techniques including planting cover crops and using terraces.

Let’s go step by step to fill in the blanks using the words from the box:
beans, grasses, rotate, irrigate, steps, terraces

---

Sentence 1:
*Farmers can plant crops such as ______ / ______ to cover the soil.*
→ We need two types of plants that help cover and protect the soil. From the list, beans and grasses are both common cover crops. Beans add nutrients, grasses hold soil with roots.
✔ So: beans / grasses

---

Sentence 2:
*Farmers can ______ the soil with water.*
→ This is about adding water to dry soil. The word for that is irrigate.
✔ So: irrigate

---

Sentence 3:
*Farmers can ______ the crops grown on the land.*
→ This means changing what crop is planted each year to keep soil healthy. That’s called rotate (as in crop rotation).
✔ So: rotate

---

Sentence 4:
*Farmers can plant their crops on ______ / ______, around the sides of hills.*
→ On hillsides, farmers build flat areas to prevent erosion. These are called terraces, which look like giant steps cut into the hill. Both words fit here.
✔ So: steps / terraces

Final Answer:
1. beans / grasses
2. irrigate
3. rotate
