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. Click here for instructions on how to submit your own soil sample to make sure you get the balance just right. Your plants will thank you and so will Utah's water!
