Nitrogen balance as an indicator of nitrogen leaching in Finland
Agriculture, Ecosystems & Environment, 2006Abstract When measured data of nitrogen (N) losses to the environment are not available, calculated N balances are often used to indicate losses. The aim of this study was to describe the relations between N surface balances and N leaching losses in two agricultural runoff fields.

Nitrogen Fixation and the Nitrogen Balance in Peatland Ecosystems
Ecology, 1980A survey of heterotrophic nitrogen fixation was carried out using the acetylene reduction assay on peat from mires in Canada, England, Scotland, Ireland, Norway, Germany, Italy, and Malaysia. A detailed study of the relationship between nitrogen fixation and peatland ecology was carried out on the German sites.

A shift towards a negative nitrogen balance implies impairment of essential life processes. Among the substances adversely affected are: Enzymes in the Krebs cycle, resulting in impaired carbohydrate metabolism and anaerobic metabolism, with a consequent deterioration of the circulation Transport proteins in blood plasma, such as hemoglobin ...

Nitrogen Balance in Parenteral Nutrition
Archives of Surgery, 1975To the Editor.—We were interested to read "Nitrogen Balance in Postoperative Patients Receiving Parenteral Nutrition" by Van Way et al (Arch Surg110:272, 1975). We have had considerable experience in the assessment of intravenous nutritional regimens in patients undergoing elective abdominal surgery, and we agree that increasing calorie and nitrogen ...

Positive Nitrogen Balance in Burn Patients
Scandinavian Journal of Plastic and Reconstructive Surgery, 1984Two 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.

Nitrogen balance of crop production in Ukraine
Journal of Environmental Management, 2019Lands of Ukraine are intensively used. Usage of insufficient amounts of fertilizers leads to destruction of soil organic matter, causing complete loss of soil fertility. In 2015, the total nitrogen balance in Ukraine was negative. It is -152.3 Gg or -5.8 kg N/ha/yr. In different regions, these indicators varied from -34.6-24.7 kg N/ha/yr.

Nitrogen Balance in a Citrus Orchard
Journal of Environmental Quality, 1984AbstractDifferential fertilizer and irrigation applications were utilized to assess the N balance over a period of 4 yr in a typical mature ‘Shamouti’ orange (Citrus sinensis L.) grove located in the coastal plain of Israel. Nitrogen inputs in fertilizer and irrigation water were 100, 180, and 310 kg ha−1 annually for the three main treatments.

Protein Turnover, Nitrogen Balance and Rehabilitation
1983Not 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.

The nitrogen balance of laying hens
The Journal of Agricultural Science, 1934SummaryA nitrogen balance experiment of ten weeks' duration with two Rhode Island Red laying hens is described.The observed variations in the retention of nitrogen for egg-producing purposes do not appear to be connected with the output of egg nitrogen or with the number of eggs laid in the various egg cycles.The view held by other workers that the ...

Nitrogenous Excretion and Salt and Water Balance [PDF]
, 1980 Enzymatically controlled reactions occur at the optimum rate within a narrow range of physical conditions. Especially important are the pH and ionic content of the cell fluid, since these factors most easily affect the active site on an enzyme. Since the conditions existing within cells and tissues are necessarily dependent on the nature of the fluid ...
