The causes of intra-field variations in crop yields are of high interest in agriculture. Anything that can explain them, either through a mechanism or through a statistical relationship, is valuable information for farmers. This project looks at the water factor in the field. This is a small project, and is designed as a first introduction to the world of using sensors and satellites to measure within field soil water variations and thus to hopefully help explain variations in crop yields.
The plan is use a map of soil conductivity (EM38) to place out both TDR and tensiometer soil moisture sensors, then to link the logged data to satellite images and yield maps.
This project is sponsored by Agtech Sweden, based at Linköping University.
