Abstract

A method of monitoring the moisture content of soil comprises measuring a first and a second property of soil which both vary with moisture content, deriving from a respective predetermined relationship between the first property and moisture content for each of a plurality of different soil types a first moisture content value for each of said soil types, deriving from a respective predetermined relationship between the second property and moisture content for each of said plurality of different soil types a second moisture content value for each of said soil types, comparing the first and second values for each soil types and selecting the pair of values for which the difference is smallest, and calculating the average of the selected pair of first and second moisture content values to give the moisture content of the soil. A monitoring device (1) for use in monitoring soil moisture content comprises a control means (60) and a plurality of moisture sensing elements (35, 36, 37) insertable into the soil and connected to the control means (60), each sensing element (35, 36, 37) being arranged to sense moisture content at a different depth in the soil from the other elements, the control means (60) co-operating with the sensing elements (35, 36, 37) to provide data representing soil moisture content at a range of depths, the control means (60) being connected to a radio transmitter (65) for transmitting the data in conjunction with an identifying code for the device.
