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 ...

Book excerpt: The book will serve as a text-cum-reference book on trace elements for students, teachers, research students, extension workers and progressive farmers. Chapter 1 to 7 briefly introduce the reader to all important general aspects of trace elements in the soil and plant systems with suitable examples and illustrations. Chapters 8 and 9 deal with trace elements essential to plants and also those which are important for animal and human health. The book gives information in an easily understood form about lower and upper critical limits for trace elements in soil and crops, physiological roles/effects, deficiency and toxicity disorders (biochemical, histological and visual). A new section on radionuclides is also introduced.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.
