Genetic Improvement of Crops was first published in 1980. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.Recent years have seen the emergence of a number of in vitro techniques that hold promise for the genetic alteration of higher organisms by non-traditional means. These new techniques may eventually modify the genetic structure of cash crop plants and, in practical terms, may lead to substantial improvement of crop production and to disease resistance in plants.This volume brings together 10 research reports by scientists actively engaged in developing genetic techniques in plants and other organisms. The first section explores both the potential for application of these techniques and the genetic needs of plant breeders. Other sections deal with genome organization and function; recombinant DNA technology and application; gene transfer; organelle transfer; and plant tissue culture.

Vaclav Smil
R618 R477 Discovery Miles 4 770 Save R141 (23%) Shipped within 7 - 12 working days

Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber-a discovery scientists had sought for over one hundred years-and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.

Phosphorus Management in Crop Production (Hardcover): Nand Kumar Fageria, Zhenli He, Virupax C. Baligar Phosphorus Management in Crop Production (Hardcover)

R3,080 Discovery Miles 30 800 Shipped within 7 - 12 working days

The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.

Nitrate and nitrite are two ions largely diffused in the environment because they take part in the nitrogen cycle. Moreover, a great part of atmospheric nitrogen may be oxidized to nitrite and nitrate by microorganisms in plants, soil or water. The more stable form of oxidized nitrogen is nitrate ion, but, through microbial activity, it can be reduced to nitrite ion which is more chemically reactive. Nitrate and its salts are widely used, especially as inorganic fertilizers, and for many other purposes such as oxidizing agents, explosives, in the chemical industry and as food preservatives. This book discusses the agricultural uses, management practices and environmental effects of nitrogen fertilizers.

Organic farming is a system approach utilizing the natural cycles and biological interactions for crop production and protection. It aims at harmonizing with nature and a method of production without destroying the environment. Vermitechnology is one of the important components of organic farming. The earthworm (verm) is now known to be a good biological element for the recovery of vermifertilizer and vermin- protein for use in agro-ecosystems, aquaculture, poultry etc. Earthworm culture, popularly called vermiculture is being widely practicised in a big commercialized manner. Therefore, it is high time to enter into the vermitechnology as a part of the biotechnology programme. In India, some companies have adopted vermiculture, but by and large the general awareness remains limited, despite the fact that several non-governmental organizations and governmental institutions are trying hard to popularize vermitechnology. This book is an attempt to help those desirous of starting a vermicutlure and vermicompost industry. Based on this rationale, the Vermiculture Research Station in Aligarh, India embarked on an extensive programme of transferring vermitechnology to the farmers back in 2000 under the Lab to Land programme. The farmers were given specialized training through field demonstrations in vermitechnology, organizing special courses and setting-up their own field units in rural areas. It is heartening to note that female farmers have also come forward in this new venture and are now producing quality vermicompost to supplement their income.

The world population will grow more rapidly during the few coming years. This must be accompanied by a parallel increase in the agricultural production to secure adequate food. Sustainability considerations mandate that alternatives to chemical nitrogen fertilizers must be urgently sought. Biological nitrogen (N2) fixation, a microbiological process which converts atmospheric N2 into a plant-usable form, offers this alternative. Among these renewable sources, N2-fixing legumes offer an economically attractive and ecologically sound means of reducing external inputs and improving internal resources. Environmental factors such as drought, elevated temperature, salinity, soil acidity and rising CO2 are known to dramatically affect the symbiotic process and thus play a part in determining the actual amount of nitrogen fixed by a given legume in the field. Understanding how nodule N2 fixation responds to the environment is crucial for improving legume production and maintaining sustainability in the context of global change. In this thoughtful and provocative new Brief, we provide critical information on how current and projected future changes in the environment will affect legume growth and their symbiotic N2 fixing capabilities. Each section reviews the main drivers of environmental change on the legume performance that include drought, elevated temperature, salinity and rising CO2, and soil acidity. Importantly we discuss the molecular approaches to the analysis of the stress response in legumes and the possible biotechnological strategies to overcome their detrimental effects.

The dramatic worldwide increase in agricultural and industrial productivity has created severe environmental problems. Soil and groundwater reservoirs have been polluted with pesticides, xenobiotics and agro-chemicals. The global consensus to reduce inputs of chemical pesticides and agrochemical fertilizers, which are perceived at being hazardous by some consumers, has provided opportunities for the development of novel, benign sustainable crop management strategies.

The future of agricultural depends upon our ability to enhance the productivity without damage to their long-term production potential. One of the strategies is the application of effective microbial products beneficial for both farmers and ecosystems. This kind of approach can ensure both ecological and economic sustainability. Soil microbial populations are immersed in framework of interactions, which are known to affect plant fitness and soil quality.

For betterment of life of human being, improved quality and variety of products are formed due to versatile action of different group of microorganisms, Microbes are able to degrade solid waste material into compost which is a mixture of decayed organic matter, manure etc. Incomplete microbial degradation of organic waste where the microbial process varies aerobic to anaerobic form is stated as compost, if added to soil improves plant growth and development. The biological activities and microbial metabolism in the soil contribute to alter its mixture and fertility. Incorporation of organic remain in the form of compost is known to influence favourably the physio-chemical and biological properties of soil. The beneficial activities bestowed upon plants by compost utilization are multifaceted, hence most promising alternatives for achieving sustainable agricultural production.

An increased awareness on compost has led to their use in agricultural concern. Contents in the present book will comprised various chapters on the role of beneficial bacteria in the composting process. The application is depicted to achieve the attainable productivity besides, in disease management and suppressiveness of organisms of phytopathogenic in nature. Significance of the compost elicits certain responses e.g. soil reclamation, soil fertility, soil health and disease management exhibit due to quality compost amendment in soil. It serves as low cost prospective option for sustainable crop production and protection.

The presented book describes the results of the research of the project titled Phosphorus Renewable Raw Materials A Resource Base for the New Generation of Fertilizers attributed to the National Center for Research and Development of Poland. This book is divided into three chapters that are assigned to different stages of the project undertaken by different R&D institutions. The concept and possible options of valorization of waste biomass, such as bones, fish bones, and ashes originated from the incineration of sludge from a waste-water treatment plant from the tertiary stage of biological treatment as resources of phosphorus were described by the team from Wroclaw University of Science and Technology. As a method of by-products valorization, the solubilization process was proposed. Two strategies were proposed: Ex-situ and in-situ. The in-situ manner resulted with suspension fertilizer with a low concentration of P2O5 while ex-situ gave the possibility to obtain two solid formulations with the high content of P2O5. All of them could be used in agriculture and horticulture as granular fertilizers or as substrates. The different content of P2O5, as well as other nutrients in obtained formulations, were described as an effect of utilization of different raw materials as well as various additional substances such as binders necessary for the stability of final formulations. What is more, the efficiency of obtained formulations was strongly related to the kind of microorganism used as an activator of unavailable phosphorus, which was discussed in details. The technology of production for biofertilizers in pilot-scale was described by the Institute of New Chemical Synthesis in Pulawy with the following issues underlined: Design of installation to produce fertilizers based on renewable raw materials; plant construction and production of the product; and preliminary economic analysis. The University of Warmia and Mazury in Olsztyn described the utilitarian properties of new fertilizer formulations that were evaluated in field tests with special attention to granular and suspension biofertilizer. In that chapter, the major results of the agronomic evaluation of new suspension and granular phosphorus biofertilizers from secondary raw materials (sewage sludge ash, animal bones, and animal blood) were presented. Biofertilizers contained Bacillus megaterium or Acidithiobacillus ferrooxidans bacteria. New bioproducts were tested in field experiments in reference to traditional commercial phosphorus fertilizers (superphosphate, phosphorite, etc.). The research confirmed that phosphorus biofertilizers from renewable raw materials were similar to commercial fertilizers in terms of their crop-enhancing efficiency and did not reduce yield quality and quantity.
