Worked Solution & Example Answer:Many farmers reseed grassland on a regular basis - Leaving Cert Agricultural Science - Question a - 2019
Step 1
State two reasons why grassland may have to be reseeded.
Answer
-
Poaching damage or poor quality grasses: Overgrazing by livestock can lead to soil compaction and damage to grass plants, resulting in a decline in grass quality and yield.
-
Weed infestation: The presence of weeds can significantly reduce the productivity of grassland, thus re-seeding may be necessary to improve the overall yield and quality.
Step 2
Step 3
Explain the reason for using any one of the grass species named.
Answer
Perennial ryegrass (PRG) is often used because it is palatable and productive. Its traits make it suitable for grazing, as it offers high digestibility and a long growing season, thereby supporting livestock health and productivity.
Step 4
State two reasons why grassland is topped.
Answer
-
Increases tillering: Topping encourages the growth of new shoots, leading to denser grassland which can improve yield.
-
Weed control: Topping helps to manage weeds by removing seed heads, thus preventing them from spreading and competing with the grass for nutrients.
