If there were no nitrogen compounds in the soil the most immediate effect on plants growing in the soil would be difficulty in synthesizing?

If there were no nitrogen compounds in the soil, the most immediate effect on plants would be difficulty in synthesizing essential proteins and nucleic acids, such as DNA and RNA. Nitrogen is a critical nutrient for plant growth, as it is a key component of amino acids, which are the building blocks of proteins. Without adequate nitrogen, plants would exhibit stunted growth, yellowing leaves, and reduced overall health, ultimately affecting their ability to thrive and reproduce.
