With RiverFox, you receive clear, yield-maximizing irrigation recommendations - individually for each field and taking into account the crop type and sowing time. Mobile monitoring of your fields on your smartphone and desktop: Never forget to irrigate a field or shut a pipe again! With RiverFox you always have an overview of your fields. Get new soil moisture information daily by analyzing satellite images and weather stations. If a critical value is under- or exceeded, a warning appears directly on your cell phone. Precise cost analysis and automatic documentation of irrigation for your quality assurance! With RiverFox you can digitally coordinate all irrigation measures and have your irrigation documented for quality assurance. The record-keeping allows you to accurately analyze your irrigation costs at the end of the season. Optimize irrigation timing to better coordinate peak workloads! Coordinate your employees, take into account crop protection measures such as fertilizer service, your seed calendar and distribute tasks digitally. The RiverFox irrigation app shows you which fields need irrigation, helping you prioritize, allocate tasks and grow vegetables. RiverFox is intuitively designed so even foremen in the field can make the right decisions. Use your water rights wisely at the right time! The agriculture industry is experiencing more and more restrictions on irrigation. With RiverFox, you can irrigate more efficiently and save water rights. This way you avoid crop damage. The saved water rights can be carried over to the next year. RiverFox users can irrigate and harvest on all fields even in dry years - and enjoy high yields on all fields. With RiverFox, you get mobile soil moisture and agricultural weather information for your crops. The analysis of satellite images with the possibility to connect your own weather station achieves field-accurate irrigation suggestions. With the Geisenheim model, market gardeners receive irrigation forecasts individually for their crop (from corn to potatoes to cut lettuce) and can thus optimize their cultivation. The artificial intelligence behind the analyses of satellite images and weather data works very accurately. Moisture measurements are now possible for the first time without additional equipment and associated maintenance. This is a decisive cost and effort advantage over conventional methods of soil moisture measurement. Rainfall forecasts are taken into account with field accuracy for the first time, increasing the reliability of recommendations. Desiccation warnings help prevent plant damage.
