Actual soil fertility is the amount of nutrients and moisture derived from the soil by the plants in a given year.
A soil test indicates which nutrients are lacking. Most plant nutrition comes freely from the carbon, hydrogen and oxygen in the air and water. Fertilizer and organic matter worked into the soil provide the remainder of the nutrients, if soil conditions require a boost to help the plants thrive.he micronutrients boron, manganese, copper, zinc, chlorine, nickel, cobalt and molybdenum are required in such minute amounts for plant growth that lack is not particularly a problem.
