Available in PDF, EPUB and Kindle. Book excerpt: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses measured in each experiment were yield, content and uptake of zinc, phosphorus, iron and manganese. The susceptibility of the five plant species to zinc deficiency ranged from very severe in sweet corn and bush beans, moderately to slightly severe in potatoes and tomatoes and tolerant in wheat. The soils used throughout these experiments were both phosphorus and zinc deficient. Phosphorus deficiency was the most limiting factor to plant growth and zinc deficiency could not be observed in susceptible species until phosphorus needs were met. In no instance did phosphorus application interfere with zinc uptake and in fact, higher levels of applied phosphorus increased the total uptake of zinc. Zinc deficiency nevertheless resulted because the supply of available zinc in these soils was inadequate to meet plant needs. Phosphorus content was greatly elevated in susceptible species when zinc deficiency symptoms were observed. Iron and manganese contents were greatly elevated in zinc deficient sweet corn whereas an increased content of these elements occurred only in the most severely zinc deficient bush beans and not at all in other species.

Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The Second Edition of this book retains the aim of the first in presenting the principles of mineral nutrition in the light of current advances.This volume retains the structure of the first edition, being divided into two parts: Nutritional Physiology and Soil-Plant Relationships. In Part I, more emphasis has been placed on root-shoot interactions, stress physiology, water relations, and functions of micronutrients. In view of the worldwide increasing interest in plant-soil interactions, Part II has been considerably altered and extended, particularly on the effects of external and interal factors on root growth and chapter 15 on the root-soil interface.The second edition will be invaluable to both advanced students and researchers.Key Features* Second Edition of this established text* Structure of the book remains the same* 50% of the reference and 50% of the figures and tables have been replaced* Whole of the text has been revised* Coverage of plant (soil interactions has been increased considerably)
Download or read book Genetic Aspects of Plant Nutrition written by M.R. Saric and published by Springer Science & Business Media. This book was released on 1983-09-30 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of addressing the problem of the genetic specificity of mineral nutrition at an international level arose four years ago in a proposal for this topic to be included in the program of the II Congress of the Federation of European Societies for Plant Physiology (FESPP) as a separate section. The Organising Committee of the II Congress of FESPP which was held in Santiago de Compostella in 1980 arranged a special session and it was clearly successful. A special scientific meeting where the genetic aspects of plant nutrition in their widest sense could be presented and discussed comprehensively appeared to be necessary and that is how this Symposium came to be organized by the Serbian Academy of Sciences and Arts. Much progress has already been achieved in this field, and bearing in mind the importance of this problem, particularly at the present moment, it is necessary for us both to acquaint ourselves with what has been achieved so far, and even more to direct attention and effort to the fundamental problems for the future.
Download or read book Phosphorus Management in Crop Production written by Nand Kumar Fageria and published by CRC Press. This book was released on 2017-02-17 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Biochemistry of Metal Micronutrients in the Rhizosphere written by John Manthey and published by CRC Press. This book was released on 1994-03-22 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry of Metal Micronutrients in the Rhizosphere focuses on chemical factors and biological activities that control the uptake and translocation of essential metal micronutrients by plants and microorganisms. Emphasis is placed on current proposals describing the roles of microorganisms in controlling the biological activities of metal micronutrients in the rhizosphere. Coverage includes basic principles of siderophore-mediated Fe acquisition by microorganisms, siderophores as important regulators of Fe availability to plants and rhizosphere microorganisms, and microbial control of metal micronutrient supply to plants. The book evaluates plant uptake processes of Fe, Mn, and Zn in solution cultures and integrates this information with a rapidly developing understanding of rhizosphere events. Important consideration is given to the roles of metal ion chelation and soil chemistry in these biological activities. The current understanding of the biochemical events associated with Fe-deficiency in plants is discussed, including how these activities mediate micronutrient availability to both plants and soil microorganisms. This unique mixture of detailed coverage of the events that control biological activities of Fe, Mn, and Zn in the rhizosphere makes this book an essential reference.

Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in the Department of Soil Science, University of the Philippines at Los Banos, from January to July, 1980 with the following objectives: 1. to evaluate the influence of phosphate fertilizer on the availability of zinc to the rice plant when grown in the soils with varying properties: 2. to determine the effect of phosphate fertilization on the zinc adsorption capacity of 5 Zn-deficient paddy soils; and 3. to determine the relationship between zinc adsorption characteristic and P-Zn interaction. Soils samples were collected from Zn-deficient areas representing 5 soil types, namely: Quingua sl, San Manuel scl, Calumpang sl, Mandaue cl, and Guadalupe c. In the zinc nutrition study, rice variety, IR 36, was grown in the greenhouse for 40 days using the Neubauer seedling technique. The soils were fertilized with 0, 30, and 60 ppm P as P2O5 and 0, 2, and 4 ppm Zn along with 50 ppm each of nitrogen and potassium. There was no interaction Zn-P fertilization and height, and between fertilization and dry matter production. However, significant difference were observed among soil types. Laboratory analysis showed that, except in San Manuel scl, phosphate fertilization and soil interaction resulted to a significant reduction in the zinc uptake by plants and increased zinc accumulation in roots. The translocation of zinc from roots to tops expressed as a ratio was significantly affected by the soil interacting with zinc and phosphate fertilization. Except in San Manuel scl, Zn ratio ...
