Err... nitrogen is not a protein.
And I'm not saying to empty the reservoir. Just stop adding nitrogen late flower. Just one opinion...
Humans eat protien, and turn it into Nitrogen. Plants skip the process.
Nitrogen is quantitatively the most important nutrient that plants acquire from the soil. It is well established that plant roots take up nitrogen compounds of low molecular mass, including ammonium, nitrate, and amino acids. However, in the soil of natural ecosystems, nitrogen occurs predominantly as proteins.
Soil organic matter contains nitrogen predominantly as protein.
Complex Protien sources have to be broken down into nitrogen, and are not directly available to plants, until its broken down.
Fish ( Protien ) is one example of a Nitrogen Source after its broken down into the soil. Humans eat fish as a Protien Source, and out bodies break it down to Nitrogen.
How does nitrate affect plant protein production?
Unlike animals that can derive amino acids by consuming plants and other organisms, plants depend hugely on soil nutrients for their protein supply. Because nitrate is one of the main elements in protein, agricultural systems use nitrogen fertilizers to replenish nutrients in the soil and aid plants in generating needed proteins.
Because nitrate is one of the main elements in protein, agricultural systems use nitrogen fertilizers to replenish nutrients in the soil and aid plants in generating needed proteins. The nitrates are converted into amino acids, synthesized into protein and stored in different places in the plant. Only a small percentage of nitrates, however, get absorbed by plants, and the remaining nitrogen leaches into either the soil, the air or water.
