What is Blue Thumb Up?

 Blue Thumb Up is a simple and easy to use web app that helps you to project the soil water balance of your field in the next 4 days. It is specifically tailored at farmers that do not have access to software and sensors to help them assess crop water requirements. The information that BTU provides helps you understand the soil water balance and gives insight if you need to apply irrigation to your crop. The soil water balance is calculated on the basis of the geographic location of your field, a weather forecast, crop parameters and an estimation of the soil water content.
