VRA and Spot spraying

VRA

To minimize nitrogen leaching into groundwater, farmers are required to adhere to established nitrogen quotas. This is where precise fertilization management becomes essential, as it allows you to maximize the effectiveness of your nitrogen fertilizer while simultaneously preventing leaching.

This ensures that plants receive exactly the right amount of fertilizer they need —no more, no less.

Redistributing nitrogen minimizes the risk of over-fertilization in specific areas of the field, thereby reducing nitrogen leaching potential and achieving a better nitrogen balance. This approach also prevents under-fertilization in certain sections, leading to more uniform crop growth and enhanced harvesting efficiency for the combine.

By implementing variable rate fertilization, you can often achieve higher yields and increased protein content, while significantly improving your chances of reaching the optimal nitrogen levels.

The PerPlant sensor has a field view of 42 meters, allowing it to grade your fertilizer across a corresponding width. It is designed for retrofitting and can be integrated with any equipment that supports ISOBUS connectivity.

Spot spraying

Spot spraying is increasingly recognized as the future method for tackling problematic weeds. This technique involves applying chemicals only to specific areas where the weeds are present, rather than covering the entire field. For instance, thistles often grow in patches, making them ideal for spot spraying. Similar to graded fertilization, spot spraying is also more environmentally friendly, as it reduces chemical usage and minimizes impact on surrounding crops and ecosystems.

When discussing spot spraying, it's important to differentiate between various categories: green on brown, green on yellow and green on green. Among these, green on green is currently the most challenging method for accurately targeting the weeds.

The PerPlant sensor can achieve spot spraying with precision as fine as 10 cm by 10 cm, although this level of accuracy may vary depending on the specific sprayer used.
However, the green-on-green method is not yet fully precise but is available to a certain extent and is currently under continuous development.
