|Nitrogen is one of the elements plants must have in order to grow, but either too much or too little of it can be bad for plants. It must be provided in a form plants can use and it needs to be replenished in the soil periodically. It is necessary for the above-ground (vegetative) growth and helps the plants to maintain a good healthy green leaf color. For these reasons nitrogen is usually included in general purpose fertilizers.
