A large percentage of our work in the PCT Agservices businesses involves the collection and management of spatial GIS data, and applications for the use of that data via management and analytics. Our challenge has been to develop methods of measuring soil physical characteristics that are repeatable and reliable, and accurate to a reasonable degree of confidence, largely revolving around spatial estimation of soil water and subsoil constraints.
Our methodology, whilst still a work-in-progress, is improving as we develop methods that can be utilised in day to day farming operations as diagnostic, risk management, and predictive tools, at field scale.
