Geographically reference data layers are the foundation on which we build our cropping plans.
In 2009, we took our precision-agronomic practices to the next level. We took EM or (electromagnetic) surveys of each of our fields. EM-mapping measures soil properties such as soil texture, water holding capacity, salinity, bulk density and cation exchange capacity. The survey maps the spatial variability of these soil properties on 70′ paths at 2 meter resolution. RTK (Real Time Kinematic) elevation measurements were also recorded to ...Continue Reading →
