Working from the soil up Michael Wells, finds that EM38 maps and elevation data, combined with targeted on ground soil sampling usually provide key clues to causes of yield variability. He specialises in gathering data and using GIS software to interrogate the data to build new layers to help answer specific questions.
The results of his work enable him to report to a farmer where inputs and management could be modified in line with paddock variability. But it is the land manager and/or agronomist who use his information to determine the final rates or management changes applied.
The following example illustrates how his PA consultancy assisted a broadacre farmer and his agronomist to make more targeted decisions in their mission to improve paddock productivity.
