Description

Part 1 The nitrate problem in agriculture: Nitrogen dynamics in natural and agricultural ecosystems; Predicting nitrate losses from agricultural systems: Measurements and models; Fate of nitrogen from manufactured fertilizers in agriculture; Using a rotational modelling system to explore the effect of straw incorporation on the efficiency of nitrogen use; Assessing the importance of soluble organic nitrogen in agricultural soils; Average fertiliser nitrogen use and estimates of nitrogen uptake by major arable crops in england and wales; Nitrate in ensiled grass: A risk or benefit to livestock production? The effects of elevated atmospheric carbon dioxide concentrations on nitrogen cycling in a grassland ecosystem. Part 2 Environmental aspects of nitrates: The atmospheric nitrogen cycle and the role of anthropogenic activity; Nitrates in soils and waters from sewage wastes on land; The role of nitrates in the eutrophication and acidification of surface waters; Toxicity of nitrite to freshwater invertebrates; Sensitive areas, vulnerable zones and buffer strips: A critical review of policy in agricultural nitrate control; Considerations of the amino nitrogen in humic substances; Fertilizer and nitrate pollution in India; Status of nitrate contamination in ground water near Delhi: A case study. Part 3 Nitrate and health: The metabolism of dietary nitrites and nitrates; Identification of nitrate reducing bacteria from the oral cavity of rats and pigs; Potential risks and benefits of dietary nitrate; Metabolism of nitrate in humans: Implications for nitrate intake; Bacterial nitrate reductase activity is induced in the oral cavity by dietary nitrate; Antimicrobial effect of acidified nitrite on gut pathogens: The importance of dietary nitrate in host defence; Effects of nitrates and nitrites in experimental animals; Nitrate exposure and childhood diabetes.
