As soil nutrient concentrations raise, the likelihood of crop response to additional nutrients decreases. The world the place crop response commences to lower gets the beginning of the best possible. While in the optimum zone, including nutrients is not as likely to influence crop creation. Over the best possible may very well be a concern about some nutrients like phosphorus. Wherever soil phosphorus amounts are greater than crops can utilize, There may be likely for air pollution and water top quality issues.
