Chinese researchers produced a chip that allows on-site determination of
nutrients in soil. This tool will help boost crop growth in farms.



Nutrients, such as potassium, nitrogen, and phosphorus, are crucial for crop
growth and agricultural production. That is why it is important to quickly
and accurately detect soil nutrients to guide fertilization practices.



Researchers from Hefei Institutes of Physical Science of the Chinese Academy
of Sciences and Anhui University of Science and Technology made a
microfluidic chip with capacitively coupled contactless conductivity
detection (C4D) and integrated 3D microelectrodes for on-site soil nutrient
analysis. This low-cost system showed excellent performance, and has
high-sensitivity and stability, which will be beneficial for farmers.
