Using only yield maps in order to make an estimation crop production for nutrient management by not taking into consideration measuring other potential factors as temporary yield-limiting factors such as pest incidence makes an waste of time, resource and effort to make a precision estimation (Goulding & Whitmore 2008).

Generally more than one layer of information is required to find out comparison data and similarities among patterns in order to find nutrient management areas. Furthermore is a right reason for N patterns to exist in fields and as well to have these patterns stable during some years. ’’Zones can be constructed and managed for N using a fraction of the number of soil samples required to reveal the same zones through grid sampling’’ (Franzen & Kitchen 2008). Zone sampling therefore creates opportunities for farmer to achieve lower sampling costs for the variable rate of fertilizer that have to be applied and increases the rate of precision farming to be more convenient for producers of commodity crops.

After this step the next one would be to develop computer models to automate the zone development process and furthermore reviewing several maps in order to create and draw zone boundaries (Franzen &
