Measure grass using your smartphone
A faster way to measure grass
Most pasture-based dairy farmers know grass measurement matters. The challenge is making it happen often enough, accurately enough, and without it taking over the day.
Plate meters work, but they take time. Spreadsheets need updating. Visual estimates are quick, but they can vary between people and paddocks.
AIMER makes it quick and simple.
Using your smartphone, AIMER estimates pasture cover as you walk the field. The data then flows into a clear feed wedge and grazing dashboard, helping you make more confident decisions from the information you have just collected.

Practical pasture information, when you need it
Measure covers in seconds
Use your smartphone to capture pasture cover readings quickly and consistently, without needing a plate meter for every walk.
See the feed wedge clearly
Turn cover readings into a practical feed wedge so you can see where grass supply sits and what needs attention.
Make better grazing decisions
Use current pasture data to support decisions on what to graze next, when to supplement, and how to respond when growth changes.
Save time on farm walks
Make grass measurement easier to fit into the week, especially when time and labour are tight.
Keep the team aligned
Give farmers, staff and advisors a shared view of pasture cover, instead of relying on memory, notes or old spreadsheets.
Built for grazing-focused dairy farms
AIMER is best suited at launch to pasture-based dairy farms that already value grass measurement, or want to measure more consistently.
It is particularly relevant if you:
already use a plate meter but want to save time
used to measure grass regularly but have struggled to keep it going
want clearer information for grazing and supplement decisions
have staff involved in grazing decisions
want pasture data that is easier to capture, share and act on
The current UK launch focus is dairy farms using ryegrass, ryegrass/clover and similar productive grazing swards.

How it works:
1. Walk the paddock
Use your smartphone to scan pasture as you move through the field.
2. Capture pasture covers
AIMER estimates pasture cover and records the data against the paddock.
3. View the feed wedge
See your pasture supply clearly and spot gaps, surpluses or paddocks needing attention.
4. Plan the next move
Use the information to support grazing order, supplement decisions and team discussion.
Practical support from people who understand grazing
Precision Grazing works with livestock farmers across the UK to improve grazing systems, business performance and resilience.
Grass grown and grass utilised are still two of the biggest drivers of performance in pasture-based livestock systems.
That is why we are working with AIMER to bring this technology to UK farms.
Our role is to make sure AIMER is introduced in a practical, farmer-first way - with support that helps farmers understand how the tool fits into their grazing routine.
This is not technology for the sake of it. It is a tool to help farmers make better use of grass.

NZ-proven. UK-ready.
AIMER is already being used by more than 500 farms in New Zealand, where pasture measurement and grazing decision-making are central to dairy performance.
UK development has been an 18 month process involving 30 farms across England, Wales and Scotland collecting 1000s of data points.
AIMER accuracy in the UK is currently 90% of covers within 250 kg DM/ha of a plate meter.
Unlike the plate meter - it gives a consistent result between users meaning any team member can measure and return the same pasture cover reading.

Frequently asked questions
Do I need a plate meter to use AIMER?
No. AIMER uses your smartphone to estimate pasture cover as you walk the paddock.
Is AIMER suitable for all farm types?
At launch, AIMER is most relevant to pasture-based dairy farms already measuring grass, or wanting to measure more consistently.
What swards is it best suited to?
The current UK focus is productive dairy grazing swards such as ryegrass and ryegrass/clover leys.
Can staff use it too?
Yes. One of the benefits of AIMER is making pasture information easier to collect and share across the team.
What happens when I register?
You will receive AIMER UK launch updates, event information, demo opportunities and details of trial access where available.
