In order for the microbes not to compete with the plant roots for nitrogen one part of nitrogen to every 20 parts carbon, or a 20:1 C/N Ratio
What is the role of Nitrogen?
The scientific name for nitrogen is N, and it is a flavourless and colourless element. The ground beneath our feet contains nitrogen, as does the water we drink and the air we breathe.
Actually, nitrogen makes up about 78% of the atmosphere, making it the most prevalent element on Earth. All living things, including us, need nitrogen.
It is essential for plant growth since too little nitrogen prevents plants from thriving, which reduces food production.
On the other hand, too much nitrogen can be hazardous to plants. Although nitrogen is essential for our food supply, too much of it can be bad for the environment.
Why is nitrogen key to life?
Lack of nitrogen causes plants to turn yellow, grow slowly, and have smaller fruits and flowers. To promote crop development, farmers may apply nitrogen-containing fertilizers to their crops.
Scientists predict that without nitrogen fertilizers, we could lose up to one-third of the agricultural products that are important for our food supply and other uses.
However, we must understand how much nitrogen is required for plant growth since too much nitrogen can contaminate streams and harm aquatic life.
Hence, the correct answer is one part of nitrogen to every 20 parts carbon.
