Typically, there are three ways to measure a soil's pH: use a pH meter, employ vinegar, or send a soil sample out to your local university's agricultural department. Most pH meters you can get at ...

Compostable pH sensor The University of Glasgow has created a pH sensor for soil testing that can be composted at the end of its life. It is an impedance-based sensor, using screen-printed ...

The cosmic ray neutron sensor is a device that can measure moisture levels by detecting fast moving neutrons in the soil and in the air just above the soil (see How the cosmic ray neutron sensor works ...

Producers sometimes face challenges that go deep into the soil. They need answers to help the soil, on site. A portable field sensor can accurately measure minerals in soils more easily and ...

Named ‘Chemically functionalised paper-based electrical gas sensor (chemPEGS)’, the team’s sensor measures levels of ammonium in soil, the compound that is converted to nitrites and nitrates by soil ...

Using a type of artificial intelligence called machine learning, it combines this with weather data, time since fertilisation, pH, and soil conductivity measurements.

Two high-tech soil sensors were on show at this year’s Cereals event, putting speed, nutrient use efficiency and microbial populations at the core of ...
