Chemical symbol: N Nitrogen is one of the three primary macronutrients. In gardening, nitrogen is the element that is most often credited for strong vegetative growth. It helps plants grow vigorously and produce a heavy yield. Among other things, nitrogen is essential for the synthesis of amino acids, which are the building blocks of proteins.

Nutrient supplement

A nutrient supplement is used as an add-on to a base nutrient. Nutrient supplements can boost yields, strengthen plants and correct nutritional deficiencies. They cannot be used alone to produce a healthy crop, but their addition to a base nutrient series brings many benefits to the plants.

Nutrient uptake

Nutrient uptake is absorption of nutrients by the plant roots. The roots absorb water and nutrients that are either available in the growing medium or fed to crops. After absorption, nutrients are transported all the way through the plant and used for vegetative growth, flowering and metabolism.
