Nitrogen Fertilization I: The Nitrogen Balance

2016
Nitrogen is the most important nutrient in agricultural production. The natural input of N is due to N fixation, especially by Rhizobium bacteria that infect the roots of legumes. Organic N becomes inorganic through mineralization, and then inorganic N is absorbed by plants.

Nitrogen balance in trout

Aquaculture, 1979
Abstract The digestibility of three experimental diets of casein—gelatin basis with varying levels of carbohydrate and protein content was studied after feeding to rainbow trout. An attempt was made to estimate true protein digestibility by an indirect method, which is based on the relationship between nitrogen intake and fecal nitrogen excretion ...

Nitrogen Balance Studies in Human Pregnancy

Obstetrical & Gynecological Survey, 1981
Sixty-eight primigravidae successfully complete a 12-day nitrogen balance study when they were between 30 and 34 weeks pregnant. Particular attention was paid to ensure that each patient ate a hospital diet quantitatively equal to the home diet; each patient ate the same every day and all food was eaten.

Nitrate and nitrogen balances in men

The American Journal of Clinical Nutrition, 1981
Nitrate is a nitrogen-containing compound that is not detected by the traditional Kjeldahl method of nitrogen analysis. Nitrate balance studies were done in order to determine if nitrate production in the human body contributes to the irrationally positive nitrogen balances that have been reported in healthy adults. Seven healthy young men, confined to

Positive Nitrogen Balance in Burn Patients

Scandinavian Journal of Plastic and Reconstructive Surgery, 1984
Two case-histories of patients with full thickness burns covering 60 and 70% of their bodies are presented. In spite of the obligatory increase in the metabolic rate, both patients had a positive nitrogen balance from the very beginning, maintained exclusively by peroral nutrition.

Protein Turnover, Nitrogen Balance and Rehabilitation

1983
Not many studies have been done on protein turnover during recovery from malnutrition. Some relevant information can, however, be obtained from measurements on normal growing animals, since rehabilitation and normal growth have in common a rapid rate of net protein synthesis.
