Soil Fertilization

I have an orchard of Citrus and Avocado Trees. I analyzed the soil and here are the results:
Texture of soil: Clay.
pH: 7.64.
EC: 0.37 dS/m. Non-saline.
Phosphorus: 5.13 ppm. Low
Potassium: 190 mg/kg. Medium/Low
Calcium Carbonate: 25%. High.
I were advised to add Calcinit or Calcium Nitrate to the soil by irrigation. Is this a right action to do?
Do I really need to fertilize the soil with Calcinit knowing that the soil contains high percentage of calcium carbonate?
