Ensure yield and quality with ease

Black or white?

Incorrect foil use can result in too high or low a temperature in asparagus beds. This can lead to
a noticeably lower quality of asparagus, whereby the heads may open early, or the asparagus may be hollow or ridged. These losses could affect up to 30%*) of the harvest volume.

Deepfield® Connect
monitors the temperature of your asparagus beds for you. Use it anytime and anywhere to find out how your asparagus is doing. The bed temperature forecast helps you to decide how to arrange to foil for the following day. The alarm function warns you of overheating. The temperature sum helps you to estimate when to start harvesting. The positioning of the temperature sensors at four different depths enables precise temperature measurements for the whole season. The data is safely transmitted to your smartphone via the Bosch Cloud.

Deepfield® Connect app
The Deepfield® Connect app provides you with a quick overview of all your fields. One glance at
the app will give you the weather forecast and temperature of individual fields.
