With SKYFLD® you can create precise PGR maps to ensure that each zone of your field receives the optimum application rate of plant growth regulators. Prevent scorch from over application and ensure you keep your crops standing. Manage the PGR rate delivery to every zone within your field to maximize the output of your crop, whilst ensuring you don’t waste or place inputs in the wrong zone.
SKYFLD® allows you to add up to three different plant growth regulators, which can be either liquid or solid. Follow the instructions in this article to learn how to create PGR maps.
How to begin
- Open your farm and select a field by clicking on it:
- At the bottom of the field details, you will see the Maps section. Select Crop protection maps by clicking on the fourth icon - . Here you will see all previously created PGR maps.
- To add a new one, click on the plus icon and choose Create Plant Growth Regulator map.
Step 1: The base
- Choose what your new PGR map should be based on. You can select and combine up to ten maps in total: biomass maps, soil maps, and yield maps. You can also use only one type of map, however, combining them gives the best results.
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.
- Optionally, you can choose which of your selected maps should have higher priority. To do that, click on the Prioritise maps button. The open will appear where you can choose the weighting for each map. If you choose a higher percentage weighting the zoning from that map will have a higher weighting in the final application map.
- Decide how many zones your PGR map should have. Each zone will have a different amount of product applied to it, depending on the biomass vitality of that area. You can choose between 3, 5, 7, and 9 zones. The map preview changes depending on the number of zones, so you can immediately see the difference.
- Below, you can create an additional headland zone (or the strip of land around your field used for machine turning). If you do so, you need to define its width in meters. Later, you will be able to decide how much PGR product you want to apply to it. You can also change tramlines orientation at this step.
Before you add product information, you need to decide on minimum crop vitality. If you use Biomass maps as base maps, you can decide on the minimum percentage rate of vitality that should be a threshold for using the PGR product on that zone. For example, if you set up min. value on 50%, all field parts where the vitality is lower will be gray and no product will be applied to them.
Step 2: Products
You can add up to three different PGR products, which can be either liquid or solid. SKYFLD® enables tank-mixing procedures that can enhance the activity of products and reduce the cost of application. The application rates for your second and third products are defined by entering an average rate, then the system uses the ratio from Product 1 to calculate the rest.
- Start by defining water volume. The amount is reflected in liters per hectare.
- Scroll down and fill in the information concerning the first product you will use. You need to define:
- Product name
- Product type: liquid or solid (rate unit changes automatically)
- Target product rate per hectare (either kg/h or L/h depending on the product type you have selected)
- Minimum and maximum products rates
- Additionally, you can add product prices to keep track of the cost and expenses
- To add second and third products click on the +Add PGR Product button at the top of the window. Fill in the information using instructions from the previous point. In the rates section, you only define the target rate - minimum and maximum rates are calculated automatically, based on the proportion you have chosen for the first product.
- At the bottom of the window, you see the total amount of the products to be used on your field. Click on the Total Cost to check on your expenses.
To proceed, click the Next: Adjust parameters button at the bottom of the window.
Step 3 - Adjustments
- Choose the machinery you will use on the field. Click on the Choose PGR machinery button and select it from the list or add a new one.
- Once you selected machinery, you can adjust the amount of product you will use in each zone of your field. You can review the amounts, leave them as calculated based on chosen maps, or regulate the amounts manually. To adjust the values use the sliders. You will see the changes in numbers below.
Tip: You can use the Repaint areas option to change the PGR map zones, headland shape or add excluded areas where no PGR products should be applied. For example, if there is a tree or pond on your field and you forgot to exclude it while creating a field, you can repaint the spot so it will be omitted. To easily spot any objects, use the Split screen mode.
- Save your PGR map by clicking on the blue button at the bottom of the window.
All done! Now, you can review the information, add the application date, export or download the PGR map.
