    VARIABLE RATE SOWING MAIZE

    This tool can estimate different soil production capacity from satellite images and give you recomendations in seeding density to achieve an optimal yield in your field

How does VRS maize works? Experiences from Italy

The new digital tool “Variable Rate Sowing” from KWS defines the ideal planting density for corn on the basis of specific field conditions. KWS combines satellite images delivering objective data with long-standing empirical values and varietyspecific know-how. After all, not all varieties react alike to changes in the planting density

How to use the tool

Register in myKWS

Login to myKWS. If you don't have an account yet, you can register for free. Enter the necessary data to be able to use this top tool.

Create plots

Activate the voucher in the tool using the codes you receive from your KWS consultant. Then create your plots for the maize crop. You can draw the plot boundaries manually or import them. Add your sowing details too.

Use maps for variable sowing

After creating the plots, you receive a specific assessment of the production capacity of your land based on satellite images recorded over several years. The calculation process can take up to 24 hours. You can export the seeding maps and transfer them to the seed drill's isobus terminal.

Frequently asked questions about variable rate sowing

Variable Rate Seeding of KWS varieties

It is important that the location, variety and stand density are coordinated. Only then can you benefit from the advantages of site-specific sowing. This is where you can benefit from our experience. The following table will help you decide which stand density suits which variety under which conditions and how much the stand density should be varied when soil conditions change.
