This book comprises the contributions of the international workshop Boron 2001 which was aimed at gathering all relevant information on recent developments in boron research in soils, plants, animals and men over the past years. Review articles and original contributions deal with both applied and basic aspects in this area, comprising topics such as methods for B determination, the physiological functions of boron in plant and animal metabolism, including use of 10B for diagnostic purposes and cancer treatment. Genetic and molecular aspects of boron efficiency and tolerance to toxic levels in plants and the early physiological reactions to boron deprivation are further important topics of this volume. The role of boron for reproductive development is dealt with in further contributions. Furthermore, improved methods for the diagnosis of the available boron status in soils, plants appropriate timing and leaf fertilizer application are addressed. Special emphasis is given in the contributions to highlight the most recent developments in the aforementioned areas.

The world’s population is expected to reach 8 billion by 2025 and most of this growth in population will occur in developing countries. To feed the world with such a marked increase in population, a great improvement in food production must be achieved particularly in these countries. To meet this challenge, present agricultural productivity must be increased on the cultivated land. However, in many developing countries, particularly in Africa, reduced soil fertility caused by continuous cropping with low nutrient input and the resultant nutrient mining of soils is a major threat both to food production and to ecosystem viability. As a result of declining soil fertility, together with increasing population pressure, expansion of crop production to marginal lands and forested areas contribute to the destruction of natural ecosystems. Food production is not only a quantitative challenge. Improving the nutrient status of plants provides a further valuable means of enhancing food quality and is of extreme benefit to the health of both plants and humans. There are several excellent examples showing that plants with optimum nutrient status are better adapted to biotic and abiotic stress factors. Because of population pressures, many global food systems are not currently providing enough micronutrients to ensure adequate micronutrient intakes in the human diet. This has resulted in an increasing prevalence of micronutrient deficiencies that now afflicts over three billion people worldwide.

The International Plant Nutrition Colloquium in Hannover was the 14th in a series that started in 1954. Hannover was also selected as the venue of the 7th Colloquium held 27 years ago, in September 1974, under the presidency of J. Wehrmann. This volume is a compilation of extended abstracts of all papers presented at the 14th Colloquium. These papers include two plenary lectures which address the role of plant nutrition in the sustainability of agro-ecosystems and the production of enough high quality food to feed the growing world population. Recent advances in plant nutrition are reviewed in introductory plenary lectures in each of the Symposia devoted to: genetics and molecular biology of plant nutrition, nutrient functions, nutrient uptake and translocation, the role of the apoplast in mineral nutrition, plant quality and plant health, salinity and plant--soil--water relations, mineral element toxicity and resistance nutrient acquisition, soil organisms/plant interactions, fertiliser use in relation to optimum yield and environment, nutrient dynamics in natural and agro-ecosystems, and plant nutrition and sustainable development.Current knowledge and research emphasis in these areas of the subject is well illustrated by more than 500 oral and poster presentations and the reader is provided with a comprehensive view of the state of plant nutrition research worldwide.

The International Plant Nutrition Colloquium in Hannover was the 14th in a series that started in 1954. This volume is a compilation of the plenary lectures presented at this Colloquium. These papers include two lectures which address the role of plant nutrition in the sustainability of agro-ecosystems and the production of enough high quality food to feed the growing world population. Advances in plant nutrition are reviewed in the 11 papers presented in each of the symposia including: genetics and molecular biology of plant nutrition; nutrient functions; the role of the apoplast in mineral nutrition; plant quality and plant health; salinity and plant-soil-water relations; mineral element toxicity and resistance nutrient acquisition; soil organisms/plant interactions; fertiliser use in relation to optimum yield and environment, nutrient dynamics in natural and agro-ecosystems, and plant nutrition and sustainable development.

Boron is one of the essential micronutrients for higher plants growth and development, and more and more studies have been conducted to establish boron as an essential element in animals and humans. This book reviews all aspects of boron research in recent years and is based on the Third International Symposium on all Aspects of Plant and Animal Boron Nutrition which was held in Wuhan, P.R. China. The following issues are discussed:boron sorption mechanisms in soilsdeficiency and toxicity of boronboron fertilizer applicationbasic research on the physiology and molecular biology of plant boron nutritionthe nutritional function of boron in animals and humansThis book is aimed at scientists, Masters or PhD students focusing on boron research field. Furthermore, it provides managers involved in agricultural production with an important reference to recent developments in boron nutrition research.

This book reviews all aspects of boron research in recent years and is based on the Third International Symposium on all Aspects of Plant and Animal Boron Nutrition which was held in Wuhan, P.R. China. The following issues are discussed:

boron sorption mechanisms in soils

deficiency and toxicity of boron

boron fertilizer application

basic research on the physiology and molecular biology of plant boron nutrition

the nutritional function of boron in animals and humans

This book is aimed at scientists, Masters or PhD students focusing on boron research field. Furthermore, it provides managers involved in agricultural production with an important reference to recent developments in boron nutrition research.

The Boron '97 meeting was a great success in summarising all recent developments in basic and applied research on boron's function, especially in plants.

The Boron ''97 meeting was a great success in summarising all recent developments in basic and applied research on boron''s function, especially in plants. New techniques have since been developed and new insight has been gained into the role of boron in plant and animal metabolism. Nevertheless, there were still lots of open questions. The aim of the present workshop held in Bonn as a satellite meeting to the International Plant Nutrition Colloquium was thus to gather all actual information which has been gained since the Boron ''97 meeting and to compile knowledge, both from animal and plant sciences. Furthermore, applied aspects had to be addressed too, as there is an increasing awareness of boron deficiencies even in crops such as wheat, which have formerly not been considered as responsive to boron application. Genetic differences in boron demand and efficiency within one species are a further important topic which has gained importance since the 1997 meeting. More in-depth knowledge on the mechanisms of boron efficiency are required as an increased efficiency will be one major possibility to maintain and improve crop yields for resource-poor farmers. Nevertheless, it has also clearly been shown that an adequate supply of boron is needed to obtain high yields of crops with a high quality, and that a sustainable agriculture has to provide an adequate boron supply to compensate for inevitable losses through leaching (especially in the humid tropics and temperate regions) and for the boron removal by the crop.
