Petiole – Leaf Area Meter in a Smartphone

I enjoyed using Petiole – it is very intuitive and gave me nice, accurate leaf area measurements. It is always nice when you have technical solutions that work really well! However, my research has shifted directions. I am working much less with leaf-level physiological measurements, and more with large-scale, satellite-based measurements. There are some opportunities I see to use Petiole again – it looks like leaf mass per area (LMA) may drive some of the signal in near-infrared reflectance.

Petiole for many leaves

Спасибо разработчикам за приложение! Даже не ожидала, что есть такое, очень удобно проводить измерения, особенно, когда у тебя много листьев. Сначала были проблемы с настройками петиоль.пада, разработчик посоветовал сделать следующие шаги: прижать калибровочный лист к плоскости стола. Важно, чтоб он был ровным; приблизить камеру к калибровочному листу; попробовать другие калибровки №5 №7 №15 и все получилось!

First of all, Petiole is a precision agriculture technology company developing solutions to improve on agriculture research and decision-making about yields. We do this by providing accurate data with an advanced data analytics platform to help researchers make faster, more informed decisions. Also, Petiole works with agriculture’s leading research institutions, to remove technical challenges of specific leaf area measurement.

Petiole’s goal is to be a world leader in solutions for agriculture research. Our vision is to enable precision plant leaf data into agriculture research to make agriculture more sustainable, help in feeding the planet and stopping climate change.

How to measure leaf area with Petiole mobile application?

We have developed Computer Vision algorithms to measure specific leaf area for analysis of plant health, development and stress. Our technology captures visual data from the plant leaf and transforms it into actionable insights to researchers via mobile and cloud applications.
