The Nitrogen Atom possesses seven protons in its nucleus; therefore the electrically neutral atom of Nitrogen has seven electrons in orbit about it.

You would first calculate the atomic mass of chlorophyll, which would be 892.9 g/mol (I did not calculate this out, but looked it up b/c of the complexity of the calculation). Then find the molar mass of the Nitrogen part of the chlorophyll (4 mol *14.01 g/mol=56.04 grams). Then, take 56.04 grams/892.9grams= .06276, or 6.276% nitrogen by mass

Yes it changes with the chnage of temperature and you have to calculate the temperature correction factor

Ammonium Nitrate = NH4NO3 or N2H4O3 the total mass of a ammonium nitrate molecule is as follows: 2*14u + 4*1u + 3*16u = 28u + 4u + 48u = 80u now, the total mass of Nitrogen in one ammonium nitrate is 2*14u = 28u. Then, we divide 28 (the mass of Nitrogen) by 80 (total mass)= 28/80 = 0.35, which is the ratio for Nitrogen mass divided by total mass. then, we get the 48.5 grams (total mass) and multiply it by this ratio (0.35): 48.5 * 0.35 = 16.975 grams of Nitrogen in 48.5 grams of Ammonium Nitrate.

I believe you determine Organic Nitrogen by subtracting Ammonia Nitrogen from Total Kjeldahl Nitrogen.

divide the total grams of protein by 6.25 to find out gm of nitrogen. Calculate the total number of non protein calorie. Divide the total # of NPC by gm of nitrogen will bw the answer.

Organic manure has liquid fraction and solid fraction bot contains an amout of nitrogen. So we cannot simply add them together

Positive nitrogen balance occurs when the total nitrogen excreted in the urine, feces and sweat is less than the total nitrogen ingested. Positive nitrogen balance must exist for new tissue to be synthesized. When dietary protein intake or total energy intake is inadequate to maintain tissues total nitrogen balance, negative nitrogen balance occurs and new tissue is unable to be synthesized.

(amino acid (grams)/ 6.25)-(UUNg (urine urea nitrogen) +4g)

Nitrogen Balance = Nitrogen intake - Nitrogen loss Nitrogen intake = Protein intake (g/day) / 6.25 Urinary Urea Nitrogen (UUN) determined with 24hr urine collection Nitrogen loss = UUN (g/day) + 4g (to account for random nitrogen loss)
