Here is a general rule of thumb:
- For a 1-acre pasture, you will need approximately 10-20 lbs. of seed.
- For a 5-acre pasture, you will need approximately 50-100 lbs. of seed.
- For a 10-acre pasture, you will need approximately 100-200 lbs. of seed.
- For a 20-acre pasture, you will need approximately 200-400 lbs. of seed.
However, there are a few factors that can affect the amount of seed you need.
* The type of grass. Some grasses, such as Kentucky bluegrass and fescue, require more seed per square foot than others, such as ryegrass and Bermuda grass.
* The soil conditions. If your soil is compacted or has poor drainage, you will need to use more seed to ensure that the grass grows evenly.
* The time of year. If you are planting in the spring or fall, you will need to use less seed than if you are planting in the summer.
It is always a good idea to consult with a local nursery or agricultural extension agent to determine the exact amount of seed you need for your horse pasture.
