Agriculture in the semi‐arid and arid areas of the world requires irrigation. However, in these
areas, soils naturally contain large amounts of sodium (sodic) which can cause amongst …

To implement management plans, the salt content across affected fields and with depth
needs mapping. In this study, we developed a method to map the distribution of normal …

The alluvial clay plains of the Murray–Darling Basin (MDB) have been extensively
developed for irrigated agricultural production. Whilst irrigation has brought economic …

At the field level the demand for spatial information of soil properties is rapidly increasing
owing to its requirements in precision agriculture and soil management. One of the most …

In coastal–estuarine agricultural landscapes, shallow and often saline water tables are
problematic because they limit agricultural productivity. To understand the dynamics of …

The soil in arid and semi‐arid areas is often markedly saline, which can severely limit
agricultural productivity. Increasingly, geophysical methods are being implemented to map …

Cation exchange capacity (CEC, cmol (+) kg− 1) is a measure of the capacity of soil to retain
and exchange cations. However, it is expensive to sample and directly measure across a …

One of the most popular geophysical methods currently being used to provide information
about the spatial variation of soil properties is electromagnetic (EM) induction. This is …

The introduction of irrigated agriculture through a network of canals has seen enormous
growth in agricultural output in northeast Thailand. However, the canals are leaking causing …

Land development in the form of irrigation has led to increased agricultural productivity, but
natural stores of connate salt have led to salinization. To manage salinity, baseline …
