Book SynopsisPlants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.Table of ContentsEnvironmental and Biological Monitoring of Exposure to Pesticides in Occupationally Exposed Subjects.- Crop Quality Under Adverse Conditions: Importance of Determining the Nutritional Status.- Phosphorus Management in French Bean (Phaseolus Vulgaris L.).- Nutrition and Calcium Fertilization of Apple Trees.- Diagnosis, Prediction and Control of Boron Deficiency in Olive Trees.- Boron-Calcium Relationship in Biological Nitrogen Fixation under Physiological and Salt-Stressing Conditions.- Lime-Induced Iron Chlorosis in Fruit Trees.- Si in Horticultural Industry.- Biological Monitoring of Exposure to Pesticides in the General Population (Non Occupationally Exposed to Pesticides).

Book SynopsisThe advent of any new and effective therapy is soon followed by large numbers of publications in which the indications and benefits are explored critically. It is not unexpected, therefore, that within five years of the first Bermuda Symposium on advances in parenteral nutrition that a second Symposium was considered appropriate to review progress and explore new areas of investigation, as well as enlarging the scope of the meeting to include enteral nutrition. The rate of progress can be judged by the number of subjects which were not discussed at the first Symposium. For example, home parenteral nutrition, computer assisted assessment and prescribing, Studies of body protein synthesis and breakdown and the role of branched-chain amino acids are all new subjects for this Symposium which were not covered at all in the first meeting. Much progress has also been made to our understanding of the biochemi­ cal complications of parenteral nutrition and the problems related to long term access to the circulation. Nutritional care has become safer and more effective. There is an increasing awareness of the difficulties in making a true nutritional assessment in selecting patients for total parenteral nutrition and more attention has also been focussed on different approaches to enteral support in the management of undernourished patients. There is also continuing debate on the cost effectiveness of this expensive method of treatment and critics look in vain for evidence of efficacy based on controlled trials in specific groups of patients.Table of ContentsSection 1 Branched-Chain Amino Acids.- 1.
