Current practices in wastewater management lead to inefficient recovery and reuse of nutrients and can result in environmental problems. Source separation systems have been shown to be an efficient way of recovering nutrients and energy from wastewaters,

Nutrient balance and body composition [PDF]
The prevalence of obesity in industrialized countries is increasing in spite of decreased energy and fat intakes. This trend might be mainly a consequence of a decline in energy expenditure. It is suggested here that it might also be accounted for by the increasing proportion of protein in the diet, affecting the hormonal status. The nutrient imbalance

(N.P.K) fertilizer application levels in Onion Crops and Using the Diagnosis and Recommendation Integrated System – DRIS [PDF]
Fertilizations is one the efforts done to increase the production and quality of crops. Nitrogen, phosphorus and potassium fertilizers rate used in the production of Onion are excessive, so the essential elements present in the soil can be imbalanced ...

Nutrient digestibility and balance studies
The nutritional value of a feed for cattle depends on its nutrient and energy contents, the extent of rumen fermentation and degradation, and the post-ruminal digestibility. Efficiency of digestion depends on different factors, for example, the apparent digestibility (estimated by subtracting the nutrients contained in faeces from the nutrients ...

The gastrointestinal tract as a nutrient-balancing organ [PDF]
Failure to provision tissues with an appropriate balance of nutrients engenders fitness costs. Maintaining nutrient balance can be achieved by adjusting the selection and consumption of foods, but this may not be possible when the nutritional environment is limiting.
