Smartphone cameras offer smallholder farmers promising new access to soil health knowledge

The lack of adequate access to effective soil fertility testing in India, and much of the subtropical and tropical world, has led a group of scientists to explore how a smartphone camera might be transformed into a powerful and readily available alternative. Recently published in the Elsevier journal Biosystems Engineering, the research team describes important advances in the area of image-based soil organic matter (SOM) assessment and how it can streamline the process of evaluating soil fertility.
