Utah Phosphorous Soil Maps

Over-fertilizing isn't good for crops or water quality. These maps represent soil samples taken throughout the state over the last several years. Notice that in many cases the phosphorus levels are many times the recommended level. Adding phosphorus to the soil when it already has enough or too much doesn't help your plants and hurts water quality.
