The NMB captures the overall results of management practices, and reflects the degree of nutrient efficiency in the balance numbers and milk exports.
At all investigated temperatures, the dehydrator accomplished >90% volume reduction of ion exchanged urine, > 70% N retention and 100% recovery of P and K. To realise high degree of nutrient valorisation, this study proposes combining source separation of human urine with alkaline dehydration.
The degree of nutrient pollution is clearly reflected in higher pelagic productivity (Chl- a) and reduced water clarity (Secchi depth), the latter especially in the easternmost parts (region 6) of the Baltic Sea, (e)).
Taken together, our results were inconclusive in determining whether the degree of soil nutrient limitation alters canopy exchange of plant growth-limiting nutrients.
42 Although a degree of misclassification of nutrient intakes, based on four 24 hour recalls, is present (as with all dietary assessment methods), non-differential misclassification would most likely reduce observed associations between iron and blood pressure (although the opposite might be true in some cases).
The model results presented here indicate that there is a high degree of variability in nutrient landscape loading rates, even within the same land use class.
A high degree of resistance against nutrient enrichment has previously been demonstrated for macroalgal-dominated rocky shore communities in the presence of moderate to large amounts of macroinvertebrate grazers.
The third category is the chemically defined diets, made of chemically pure sources of amino acids, mono- or disaccharides, purified fatty acids or triglycerides, minerals, and the vitamins which represent the highest degree of control over nutrient concentrations.
A key issue when using waste feedstocks is the potential heterogeneity of supply, which demands that the cultured organism possesses a degree of flexibility in its nutrient and environmental requirements.
Lower moisture content causes reduction in solubility of nutrients of substrates, low degree of swelling, and high water tension [9].
