The application of spatial survey instruments such as EM is becoming more relevant as we utilise the technology to move towards a more objective measurement of agronomic factors, at field level, such as soil water holding capacity and soil moisture status. A better spatial understanding of the distribution of soil water holding capacity in conjunction with existing technologies such as neutron probes, is allowing for the development of tools to assist in the day to day diagnostic, risk management, and predictive tools at field scale. This allows for vast improvements in the more subjective assessment methods of soil water characteristics historically utilised in field agronomy.
