Nutrient contribution

Many different kinds of milk and milk products are available (USDA 1978 NDC 1976,1983A, 1983B). Milk has two major components fat, including fat-soluble vitamins, and milk-solids-not-fat (MSNF), which contain protein, carbohydrate, water-soluble vitamins, and minerals. The specific nutrient contribution of each of these milk products is related largely to the concentrations of milk fat and MSNF of the product. If the percentages of milk fat and MSNF are known, the values in Table 7.2 may be used to determine the nutrient contribution of a particular milk product.

The stoichiometry for cell growth is very complex and varies with micra-organism/nutrient system and environmental conditions such as pH, temperature, and redox potential. This complexity is especially true when more than one nutrient contributes to cell growth, as is usually the case. We shall focus our discussion on a simplified version for cell growth, one that is limited by only one nutrient in the medium. In general, we have... 

Since the chemical composition of alluvium obviously depends upon the source of the material, one can only make general statements about plant nutrient contributions that are related to alluvial processes. Soils vary widely as to their plant nutrient contents, as shown in Table 9.4. It should be recalled that, at most, only 5 to 10% of these totsil amounts is likely to be solubilized in any given year. Using the figure of 0.45 Tg of sediment per day carried by the Mississippi River at St. Louis, and assuming 5% dissolution of plant nutrients contained in the sediment, an estimated 90—2000 Mg of available nutrients is transported daily by this river alone. The sediment plus contained nutrients is either laid over or extends existing deposits. For example, the Po River extends its delta by about 8 X 10 m y". ... 

If the entire structure of carbofuran was usable as a nutrient source, a 100 /ig g" application to soil would supply 65 /ig of C and 6 /Jg of N. However, the nutrient contribution of carbofuran appears to be limited to the carbonyl group (11). Our estimates have shown that if carbofuran is serving as a carbon source, taking into...

Fungal colonization of fibreglass duct lining is an issue of concern for lAQ, but complexities in fungal species and nutrient contribution led to difficulties in assigning MVOCs in indoor air to this source. Hexanol, isooctanol and 6-methyl-1-heptanol (Ahearn et al., 1996), and 2-ethyl -1 -hexanol (Ezeonu et al., 1994) have been identified as major VOCs from this source. 

Phosphorus retention in wetlands is an important function in watershed nutrient cycling particularly in drainage basins with significant nonpoint nutrient contributions from agriculture and urban sources. Phosphorus retention in wetlands involves complex intercoupled physical, chemical. 

Organic fertilizers (biomass and FYM) are important elements of the nutrient contribution. The organic matter that is applied has a very complex effect on soils and plant growth. In general, the effects are as follows ... 

The purpose of farming animals is to produce food (milk, meat, eggs), materials (wool, hide) and work (draught) that are of use to man. Chapter 25 describes the trends in consumption and nutrient contribution from animal products and then considers aspects of animal production that have an influence on the environment and human health. 

Nitrogen requirements are the same as those for oats and lye. 120 kg/ha of N are recommended for a mineral soil at SNS 1. Remember nutrient contributions from organic manures. Nitrogen should be top-dressed at the end of Maich/early April depending on the SNS indices. For phosphorus and potassium requirements see Table 13.3. 

Excess nitrogen, potassium and sodium also leads to higher levels of impurities in the sugar. This makes the sugar more difficult and expensive to extract in the factory. This is now one of the measured factors determining price so it is important that growers tailor their fertiliser applications to the crop requirements and take into account the nutrient contribution from any organic fertiliser applied in the form of slurry or manure. 

Where applications of F YM or slurry have taken place account should always be taken of the nutrient contribution from these sources. 

SELECTING THE MOST NUTRITIOUS CEREALS AT THE LOWEST COST. Most of the packaged cereals sold in supermarkets have nutritional labeling, but it may not be easy for the average consumer to evaluate rapidly all of the data on the label while shopping in a crowded store. Table B-10 shows the percentages of the Recommended Dietary Allowances (RDAs) for elementary schoolchildren that are furnished by a bowl of cereal and milk, while Fig. B-46 illustrates the distribution of nutrients contributed by the cereal and the milk.
