Name two fertilizers supplying N, P, K to crops.

Fertilizers are chemically synthesized plant nutrients.

Nitrogen (N), Phosphorus (P) and potassium (K) are macronutrients and are required in large amounts by plants. So, farmers use fertilizers in order to supply these nutrients. Genesis NPK 15:15:15 + 8S, NPK A 20:20:20 are example of fertilizers used to supply N, P, K to crops.
