Soil spatial variability and its effect on crop production, particularly as determined using apparent soil electrical conductivity (ECa) measurements.
Major Project Activities:
My activities involve soil ECa measurement as a means of determining crop production potentials and field spatial variability. A major portion of my work is done in support of the precision farming research conducted by the Agroecosystem Management Research Unit.
