What is the difference between nitrogen based fertilizer and phosphorus based fertilizer?
Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. It’s also used by plants to help fight disease. Potassium helps plants make strong stems and keep growing fast.
