We designed Arvorum to help you make the best use of your resources by bringing a new level of precision into your farming operations. With Arvorum, you can create seeding maps adjusted to your equipment based on up to ten biomass, yield, or soil maps.
You can see how the map preview changes in real-time when you adjust the parameters to ensure that the maps are exactly as accurate as you need.
In this article, we explain how to create a seeding map. Follow the instructions or go directly to the section of your interest:
How to begin
1. Log in to Arvorum and click on the field you want to create a seeding map for.
2. In the Maps section, click the + Add button and select Seeding map.
|
Tip: You can also open the list of biomass maps and select one as a base for your seeding map. To do so, click Show all, click 3 dots next to the map preview, and select Create Seeding map. |
Step 1: Select base maps
1. You can select up to 10 different maps that should serve as a base for a seeding map. You can use biomass maps provided by Arvorum or upload your soil and yield maps.
Click + Biomass map, + Yield map, or + Soil map to open the lists of available maps. Then, click on the map preview to select it as a base map.
|
Tip: If you want to use only the most accurate biomass maps, you can turn on the Show clean images option. You will then see only those maps that have less than 5% of cloud coverage. |
2. By default, each base map contributes an equal amount of data to the seeding map. However, you can adjust the proportion of data taken from each base map according to your preferences. Click Prioritise maps and follow on-screen instructions or go to the dedicated article.
3. Decide how many seeding zones your map should have.
Each zone will have a different quantity of seeds applied to it, depending on the biomass vitality of that area. You will be able to decide the difference between zones (or choose the precise quantity of seeds or plants for each zone) later in step 2.
You can choose between 3, 5, 7, and 9 zones. Here you can see how seeding maps differ depending on the zone number:
4. Click the toggle to create an additional headland zone - the strip of land around your field used for machine turning. Then, enter the Widht in the input window. You will see the headland (light green) on the map preview.
5. You can also edit the tramlines orientation. To do so, click the Change Tramlines orientation toggle and set the orientation by moving the green circle on the map or entering the degrees.
6. Select the crop. Click the arrow icon to open the list of all available crops. Scroll down or use the search box and click the selected crop. Optionally you can enter the variety.
Selecting the crop or applying the seeding map will not affect the current season of your field.
7. Click the Next: Adjust parameters button at the bottom of the page.
Step 2: Choosing machinery and adjusting parameters
1. Click Choose seeding machinery and select a drill, single grain, or planter that you want to use for seeding. Pixel orientation on the map adjusts to the parameters of your machinery. If you don’t have any items on the list, click +Add new machinery. In this article, you can learn more about adding equipment.
2. Choose your target plant population and adjust the seeds or plants per zone. That depends on what type of equipment you have chosen. For detailed instructions, pick one of the items from the list below:
Drill
1. In the Calculate section, enter the target plant population (the number of plants per square meter).
2. Add the thousand grain weight (TGW) of your crop in grams.
3. Enter the germinability rate (or what part of your seeds you predict to sprout and grow) of your crop.
4. In the Result section, you will see the seed rate (in kilograms per hectare) and the quantity of seeds you will need per square meter. If you wish, you can adjust the seed rate manually.
5. At the bottom of the page, you will also see the total quantity of seeds (in kilograms) that is required to apply the seeding map.
If you want to know its total costs, you can use the Cost calculator - click the icon and enter the price per kilogram.
6. Below, you will be able to adjust the quantity of seeds per zone. Depending on how many zones you have chosen in step 1, you will see several sliders. Here is how it looks for a map with five zones:
The darkest red colour represents the areas of your field that have the lowest biomass vitality. The bright yellow colour represents high vitality zones.
By using the top slider (Differentiate zones equally), you can adjust the gap between zones. It represents the difference in the seed rate between each zone. Positive gap values mean that more seeds will be applied to low vitality zones and fewer to high vitality zones. Negative gap values determine that fewer seeds will be applied to low vitality zones and more to high vitality zones. The gap cannot be higher than 50% percent.
| Example: Your map has five zones. The average (middle) zone has a seed rate of 100% - which, in this case, equals 150 kilograms. You set the Differentiate zones equally slider to 10%. That means that for the other zones, the seed rate is going to be as follows: 120% (180 kg) for the lowest vitality zone (dark red), then 110% (165 kg), 90% (135 kg), and 80% (120 kg) for the highest vitality zone (bright yellow). |
You can also adjust the slider and the seed rate for each of the zones individually.
8. If you have created a separate headland zone in step 1, here you can also set a separate target just for this area.
Single grain
1. In the Calculate section, enter the target plant population (the number of plants per hectare).
2. Add the expected establishment (germinability) rate - or what part of your plants you predict to sprout and grow.
3. In the Result section, you will see the plant base (in seeds or plants per hectare), the planting distance, and the number of plants per linear meter of row.
4. At the bottom of the page, you will also see the total amount of plants that is required to apply the seeding map.
5. Below, you will be able to adjust the quantity of seeds per zone. Depending on how many zones you have chosen in step 1, you will see several sliders. Here is how it looks for a map with five zones:
The darkest red colour represents the areas of your field that have the lowest biomass vitality. The bright yellow colour represents high vitality zones.
By using the top slider (Differentiate zones equally), you can adjust the gap between zones. It represents the plant base difference between each zone. Positive gap values mean that more seeds will be applied to low vitality zones and fewer to high vitality zones. Negative gap values determine that fewer seeds will be applied to low vitality zones and more to high vitality zones. The gap cannot be higher than 50% percent.
| Example: Your map has five zones. The average (middle) zone has a seed rate of 100% - which, in this case, equals 150 kilograms. You set the Differentiate zones equally slider to 10%. That means that for the other zones the seed rate is going to be as follows: 120% (180 kg) for the lowest vitality zone (dark red), then 110% (165 kg), 90% (135 kg), and 80% (120 kg) for the highest vitality zone (bright yellow). |
You can also adjust the slider and the plant base for each of the zones individually.
6. If you have created a separate headland zone in step 1, here you can also set a separate target just for this area.
Planter
1. In the Calculate section, enter the distance between plants in centimetres.
2. In the Result section, you will see the planting population (the number of plants per hectare) and the number of plants per linear meter.
3. At the bottom of the page, you will also see the total amount of plants required to apply the seeding map.
4. Below, you will be able to adjust the quantity of seeds per zone. Depending on how many zones you have chosen in step 1, you will see several sliders. Here is how it looks for a map with five zones:
The darkest red colour represents the areas of your field that have the lowest biomass vitality. The bright yellow colour represents high vitality zones.
By using the top slider (Differentiate zones equally), you can adjust the gap between zones. It represents a planting distance difference between each zone. Positive gap values mean that seeds will be planted more densely in low vitality zones and less in densely high vitality zones. Negative gap values mean that seeds will be planted less densely in low vitality zones and more densely high vitality zones. The gap cannot be higher than 50 percent. The final planting distance also depends on your machine specifications.
You can also adjust the slider and the planting distance for each of the zones individually.
5. If you have created a separate headland zone in step 1, here you can also set a separate target just for this area.
To finish creating your map, click the Save seeding map button at the bottom of the page. Next, enter the map name and click Save.
All done! Now you see the summary of map parameters. You can export the map to your terminal or as a .pdf file. To display more information, click the Details button. If you want to apply changes to your map, click Edit.
To add the application date, click the button Add application. You can add several dates. They will be displayed in the map details view.
You can also copy the application strategy and use it on other fields.
