Allocation and spot spraying

What is graduation and spot spraying,
and why is it important in today's and future agriculture?

Allocation

In order to reduce the leaching of nitrogen into the groundwater, nitrogen quotas have been set which farmers must stay within. This is where allocating your fertilization comes into play, as it helps you get the most out of your nitrogen fertilizer and at the same time avoid leaching.

The plants thereby get the fertilizer they need, and neither less nor more.

When nitrogen is redistributed, the risk of over-fertilisation in areas of the field will be minimised. It also means that the leaching potential of nitrogen is reduced and a better nitrogen balance is achieved. At the same time, underfertilization of certain areas of the field is avoided, which results in the crop becoming more uniform and the harvesting capacity of the combine is increased.

By dividing/allocating the fertilization, you will also often achieve a higher yield and a higher protein percentage, as well as a much better chance of hitting the N optimum.

The PerPlant sensor can look out into the field with a width of 42 meters, and allocate your fertilizer with a corresponding width. The sensor is retrofitting and works on all equipment as long as ISOBUS is connected.

Spot spraying
It is referred to by many as being the method of the future to control root weeds and problem weeds, as chemicals are only sprayed in spots where the weeds are located rather than the entire field. For example, thistles stand in patches and are therefore suitable for spot leveling. So, just like with allocation, spot spraying is also better for the environment.
When talking about spot spraying you differentiate between brown in yellow, yellow in yellow, yellow in green and green in green, where green in green is the most difficult method to do as of right now.
The PerPlant sensor can perform spot spraying with a precision down t 10x10 cm but depends on the specific equipment.
However, green in green is not currently available but is under development.
