What do plants use Nitrogen for?/ Why do plants need Nitrogen?
Nitrogen (N) is essential for plant growth and is part of every living cell. It plays many roles in plants and is necessary for chlorophyll synthesis and, as a part of chlorophyll molecules, is involved in photosynthesis. Lack of it means lack of chlorophyll which means the plant will not utilize sunlight as an energy source to carry on essential functions such as nutrient uptake. Nitrogen is a component of vitamins, amino acids and energy systems within the plant, which forms its proteins. Thus, N is directly responsible for increasing protein content in plants.
Without Nitrogen, plants start to yellow and wilt, and will eventually die.
Nitrate is very mobile in the soil and moves with soil water to root surfaces for plant absorption, but it needs to be available.
How do I give my plant more Nitrogen? / Where do I get Nitrogen for my plant?
No matter the media/substrate you are growing in, whether it be soil, coco, or just in water, all plants still need access to Nitrogen. How you give the nitrogen to your plants is through fertilizers, specially formed fertilizers like Complete Hydroponics which has a special organic formula for all growing media including Tierra AB, Coco AB, and Agua AB.
These products have readily available organic Nitrogen, Phosphorus, and Potassium (the three most important elements for plant life) and a dozen micronutrients (also essential for plant life).
Adding this fertilizer will give your plant everything it needs to grow and bloom, whether you are growing a garden full of roses or tomato plants in pots.
