What is it about?
Soil moisture is an important environmental variable for irrigation scheduling. Through a 7-months proximal gamma-ray spectroscopy experiment we have shown for the first time the significant bias in soil moisture assessment due to growing tomato plants and fruits.

Why is it important?
Two significant findings are that: i) by neglecting the attenuation due to water in biomass soil moisture measurements can be biased by up to 70% and ii) proximal gamma-ray spectroscopy was proved to provide a reliable continuous soil moisture monitoring at field scale.
Perspectives
Writing this article was stimulating and inspiring since it came from a fruitful collaboration among authors I work with from a long time. It also lead researchers working on soil moisture measured with cosmic neutrons contact me and I hope this can lead to a greater involvement in soil moisture measurements through new projects and experiments
