What does this map mean?
The lay of the land affects water infiltration, drainage, nitrogen and soil loss. Severely sloping soil can exhibit reduced productive potential, often due to topsoil loss. Concave, or bowl-shaped areas can be poorly drained, especially if they also have clay soils.
How can this map be used?
Topography is one of the most visible field properties and should be included with soils data in many scouting and variable rate applications, especially those involving water and nitrogen. Topography used alone can be misleading – not all 2% slopes have the same soil texture or – or yield potential.
Topographical data in combination with soil information are useful for explaining yield variability on an agricultural field scale

When coupled with Veris soil sensors, the applications for topo data are even more powerful.
The elevation data is reviewed by Veris Data Services personnel.
Only high quality data is approved—RTK or if elevation changes are large, DGPS data may be acceptable.
