What are drone-based stand counts?
Stand counts analyze the number of plants or crops on a field or a specific area on the field. Agremo stand counts show two different numbers:
- The exact number of plants or crops on your field
- How this number is performing compared to the planned number of plants or crops (in percent and plants).
The planned number is also referred to as the recommended set, and you enter it before submitting your request. It refers to the number of plants you have been expecting per acre, hectare, or square meter. If you don’t have any numbers on the expected number of plants, a standardized value can be entered, which might, however, affect the accuracy of the report.
Here’s an example of what the Agremo stand count report tells you: You expect to get around 240,000 plants on your potato field and enter this as the recommended set. You submit your stand count analysis, which then reveals that you have a total number of 182,402 potatoes in your field. This means that the difference between the counted number of plants and the planned number of plants is 24% under the norm, which is close to 57,598 plants.
If you want to count your plants without entering a recommended set, you might want to request a plant population report instead. Plant population reports will provide you the number of plants without any additional comparisons.
Use stand counts to:
- Evaluate plant emergence and germination. Spot areas with potential crop loss in time and decide whether or not to replant
- Evaluate seed quality
- Analyze the number of plants at the beginning and the end of the growing season
- Evaluate how effective replanting measures were
- Know exactly how many plants you will be able to harvest (and sell)
- Plan harvest and yield-related processes (logistics, resources).
When is the best time to use drone-based stand counts?
Stand counts come in handy for early and late season management decisions.
- Early season: plant emergence, seed quality, planting date evaluation, overall plant performance
- Late season: yield and harvest planning, yield estimation
For more information on stand counts for specific crops, see the mapping calendars in the crop section.
What are the benefits of drone-based stand counts?
There are several benefits that drone-based stand counts have compared to traditional stand counts.
Drone-based stand counts are:
- Fast and save time and resources
- Able to cover around 500 acres in less than two hours
- Accurate – with error rates lower than 2%. And with drones, you can analyze every inch of your field
- Proactive and allow effective in-season corrective measures.
In the example above, the stand count analysis revealed a 9% difference between the planned number of plants and the actual number of plants, which translates to exactly 14,372 plants. This enabled the grower to not only estimate sowing quality, but also to plan and evaluate future replants and optimize harvest planning.
