Measure soil moisture
Measure soil moisture
how much water to apply to a crop when irrigating is a detail many growers would like to know.
One solution to the problem could be to use the Soil Moisture Datalogger now being marketed by Kent-based Field. Supplied as a kit, two sensors are placed in the ground – one at 20cm and the other at 40cm – with their leads connected to a datalogger unit. Up to 960 readings of relative soil moisture can be made at intervals down to one a minute, if required.
The datalogger is then down loaded onto the office computer.
"The aim is to allow growers to achieve a relatively constant soil moisture content," says Fields Andrew Hubble. "The system will also provide a record of how an irrigation scheme performs."
Powered by a 9V battery the Soil Moisture Datalogger costs £499. *
