SKYFLD® was designed to help you make the best use of your resources by bringing a new level of precision into your farming operations. That is why you can create fertilisation maps based on up to ten biomass, soil or yield maps - that are tailor-made for your farming equipment.
To ensure that the maps are exactly as accurate as you need, you can watch how the map preview changes in real-time as you adjust the parameters.
- How to begin
- Step 1 - The base
- Step 2 - The fertiliser
- Step 3 - Choosing machinery and adjusting parameters
How to begin
1. Open your farm and select a field:
2. At the bottom of the field details, you will see the Maps section. Select fertilisation maps by clicking on the third icon - .
3. You will see the list of all the fertilisation maps for the current field that you have created so far. To add another one, click Create new.
Step 1: The base
1. Choose what your new fertilisation map should be based on. You can select up to 10 different maps for better precision. There are 3 types available:
-
- biomass maps
- yield maps
- soil maps.
You can select only one type of map or use them all.
To choose the base, click on + Biomass map, + Soil map or + Yield map and select up to 10 items from the list:
|
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. Optionally, you can choose which of your selected maps should have higher priority. To do that, click on the Prioritise maps button and follow the instructions:
3. Decide how many fertilisation zones your map should have. Each zone will have a different amount of fertiliser applied to it, depending on the biomass vitality of that area. You will be able to decide the difference between zones later in Step 2 or choose the precise amount of the base nutrient for each of them in step 3.
You can choose between 3, 5, 7, and 9 zones. Here you can see how fertilisation maps differ depending on the zone number:
4. Below, you can create an additional headland zone (or the strip of land around your field used for machine turning). If you do, you will be able to decide how much fertiliser you want to apply to it later in step 3. You can add the headland by clicking the toggle:
Once you activate this option, we will ask you to enter the headland’s width in meters.
5. You can also edit the tramlines orientation. To do so, click on the toggle and set the orientation by moving the blue circle on the map or entering the degrees manually.
To proceed, click the button Next: Fertiliser options.
Step 2: Fertiliser type
1. Select the fertiliser you are going to use. You can choose between organic and manufactured fertilisers - or add your own.
The fertilisers that you will see on the list depend on the region of your farm.
2. Each fertiliser on the list has a specific concentration of nitrogen (N), phosphorus (P2O5), and potassium (K2O) that is displayed below its name. If you need, you can adjust these values by typing a different number into the box.
3. Choose if your fertiliser is liquid or solid. For liquid fertilisers we will also ask you to provide their density (in kilograms per litre).
4. Pick your fertilisation strategy. You can choose between assimilation and differentiation. Choose Assimilate if you want to apply more fertiliser to those areas of your field where the biomass vitality is lower. If you wish to apply more fertiliser to the high productivity zones, choose Differentiate.
5. Select the base of your fertiliser. The total amount of fertiliser will be calculated based on the concentration of that nutrient. You can choose from:
- nitrogen (N)
- phosphorus pentoxide (P2O5)
- potassium oxide (K2O).
6. Enter the target amount of your base nutrient (in kilograms per hectare).
7. In the Intensity section, you can decide how much the target value of the base nutrient should differ between the highest and lowest intensity zones and the average (middle) zone. The intensity is expressed in percentage - so if you set it to 10%, the highest intensity zone will require 110% of the base nutrient, and the lowest intensity zone - 90%
|
Example: you have decided to create a map with five different zones and set the nutrient target value of 50 kilograms and the 10% intensity. That means the average (middle) zone will require 50 kilograms of the base nutrient, while for the other zones these values will equal 55 kg (for the highest intensity zone), 52,5 kg, 47,5 kg, and 45 kg (for the lowest intensity zone). |
8. Decide what is the minimum biomass vitality value for the fertiliser to be applied.
9. Below, you can see how much fertiliser you will need to apply on your field based on the created map:
If you want to know its total costs, you can use the Cost calculator - click on the icon and enter the price per kilogram.
10. Once you have finished, click the button Next: Adjust parameters to go to the last step.
Step 3 - Machinery and parameters
1. Choose a machine that will be used to fertilise your field (a sprayer or a spreader) from the list, or add a new one. You will see how the map adjusts to the working width of your equipment.
2. Under the N-Balance tab, you can set an optional nitrogen limit. We will then calculate how much nitrogen has been applied to your field so far (during the previous fertilisations) and if the current application fits within that range.
3. Below you can see the list of all the zones and their target value of the base nutrient. You can leave the values that we have calculated (based on Intensity) or enter a different value. To do so, click on the number and set it manually.
4. Use the Repaint areas option if you want to edit the map and, for example, exclude some parts of your field so the fertiliser won't be applied there. Mark the area manually by clicking on the map. Next, select the color representing the zone. Hover over the color samples to see the exact values they represent.
5. Next, click the button Save fertilisation map. 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.
