Explanation:
Detailed explanation-1: -A complete fertilizer contains all three elements (nitrogen, phosphorus and potassium), while an incomplete fertilizer contains just one or two. If a fertilizer is lacking a nutrient, there will be a zero in its place on the label (15-0-0).
Detailed explanation-2: -Fertilizers containing all three primary nutrients (nitrogen, phosphorus, and potassium) are called complete fertilizers. If high levels of phosphorus and potassium are already present in the soil, supply nitrogen alone.
Detailed explanation-3: -All plants require nitrogen, phosphorus and potassium as their primary nutrient. Thus oxygen is not considered as primary nutrient for plants.
