If you’re involved in land management in any way, you’ve likely heard of drill seeding. While it’s known as a farming technique, it is a very cost and time-effective method for grass seed distribution. But what is drill seeding exactly?
Essentially, drill seeding is a mechanical method of planting seeds directly into the soil using a machine called a seed drill or drill seed. It actually dates back as far as the 1700s, and has many benefits, like higher germination rates, stronger root systems and even greater vegetation coverage.
To help you understand if it’s the right method for you, let’s take a look at:
- How drill seeding works

How does a seed drill work?
It may sound obvious, but to do seed drilling, you need a seed drill, a piece of agricultural equipment that precisely places seeds beneath the soil surface. ‘How does a seed drill work?’ you ask.
When a seed drill is pulled across the site — whether a development space needing large-scale lawns or a farm — a cutting disc (called a coulter) slices into the soil, creating narrow planting rows. The seed is then metered from a central hopped through tubes calibrated to the ideal distribution, which releases into the furrows. Wheels or chains at the rear of the equipment then either press or cover the seeds into the ground. This placement and method not only protects the seeds from the wind, but also surface runoff and birds, while locking in moisture and nutrients essential for ideal germination.
How does a drill seeder work and compare to traditional seeding methods?
So, how does a drill seeder work compared to traditional seeding that’s so great?
Traditional seeding methods, like broadcasting or drop spreading:
- Scatters seed on top of the soil surface
- Often relies on rainfall or raking to embed seed
- Prone to high seed loss from wind, water runoff or animals
- Can result in uneven coverage and lower generation rates
- Less suited to large, flat areas requiring uniform growth
Drill seeding method:
- Places seed directly into the soil at a consistent depth
- Covers seed immediately with soil for better coverage
- Ensured strong seed-to-soil contact for higher germination rates
- Minimises seed waste and reduces the need for re-seeding
- Ideal for large,
By using a drill seeder, you have better control over seed placement, moisture retention and coverage quality, all which provides a more successful revegetation result with less effort and cost over time.
Step-by-Step Guide to the Drill Seeding Method
With an expert behind the process, the drill seeding method can be both straightforward and highly effective. Here’s how it works:
- Site preparation, to remove surface debris and relieve compaction.
- Calibration, adjusting the seed drill to the right control rate, depth and row spacing based on the site.
- Seeding pass, where the furrows are cut, seeds are placed and then covered in one motion.
- Optional fertilisation, to add nutrients depending on project needs.
- Monitoring, post-seeding for germination and early growth.
Top 5 Benefits of Drill Seeding
Drill seeding has become popular for a reason. These are some of the top benefits of drill seeding for Australian land owners and managers.
High germination rates.
As the drill seeding method places seed directly into the soil at a consistent depth, while covering it, it improves the seed-to-soil contact. This controlled placement helps seed retain moisture and access nutrients more effectively, leading to higher and more even germination rates. Unlike surface-level seeding, there’s less risk of seeds drying out, or being blown or washed away, making it a more reliable option for large-scale revegetation.
Reduced seed loss.
Because drill seeding buries seeds below the surface, it’s less likely to be lost from wind, runoff or pesky birds looking for a quick meal. It makes it more efficient than broadcast methods, especially if you’re using expensive native seed mixes. That reduction in seed loss helps lower the volume of seeds you need, saving you both time and money, while meeting strict environmental targets on-site too.
Cost effective vegetation method.
Drill seeding is a highly economical method for large, flat areas. You use less seed, don’t need to use water during application and it requires fewer labour hours than many other methods, especially hand seeding. Once calibrated, a drill seeder can quickly cover large areas with minimal work, making it an efficient choice for projects with tight budgets and deadlines.
Efficient on large and difficult terrains.
One of the many benefits of using a drill seeder is the scale they’re able to cover. Mounted to tractors or other machinery, they can cover wide, open areas fast, with consistent seed placement across the entire site. It makes it ideal for mine and environmental rehabilitation, roadsides and civil developments where time, consistency and coverage are key.
Customisable for different sites.
The right drill seeding professional can adapt the method for various seed types, soil types and terrains. Seeders can be adjusted for different planting depths and seed sizes, allowing for tailored results across different environmental zones and rehabilitation needs, which is especially important on Australian worksites that may have different conditions.
