Available in PDF, EPUB and Kindle. Book excerpt: This symposium on 'Boron in Soils and Plants' completes a quartet of reviews of the behaviour in soils and plants of four trace elements, copper, manganese, zinc and boron, selected for their importance in agriculture. The series had its genesis in a suggestion from Professor Robin Graham of the Waite Agricultural Research Institute that it would be appropriate in 1981 to celebrate the Golden Jubilee of the publication in 1931 of the first definitive evidence for the essentiality of copper in plants. The previous decade had seen a resurgence of interest in copper deficiency and toxicity in agriculture and an expansion of our understanding of the behaviour of copper in soils and plants. We therefore decided to promote a review of our understanding of the behaviour of copper in soils and plants by inviting appropriate authors to prepare reviews of 14 topics for publication in a book and presentation at a Golden Jubilee International Symposium on 'Copper in Soils and Plants'. Posters of current research were also displayed and published. Murdoch University, Perth, Western Australia was chosen as the venue because of its then current research on copper, the importance of copper in Western Australian agriculture, and the presence in Perth of many international nutritionists due to the fortuitous scheduling in 1981 of the 'Fourth International Symposium on Trace Element Metabolism in Man and Animals'.
Download or read book Soil Analysis Handbook of Reference Methods written by J. Benton Jones, Jr. and published by CRC Press. This book was released on 1999-12-20 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils. Soil Analysis Handbook of Reference Methods is a standard laboratory technique manual for the most commonly used soil analysis procedures. First published in 1974, this Handbook has changed over the years to reflect evolving needs. New test methods and modifications have been added, as well as new sections on nitrate, heavy metals, and quality assurance plans for agricultural testing laboratories. Compiled by the Soil and Plant Analysis Council, this latest edition of Soil Analysis Handbook of Reference Methods also addresses the major methods for managing plant nutrition currently in use in the United States and other parts of the world. For soil scientists, farmers, growers, or anyone with an interest in the environment, this reference will prove an invaluable guide to standard methods for soil testing well into the future. Features

Download or read book The Mobility and Plant Availability of Boron in Selected Western Oregon Soils written by David R. Parker and published by . This book was released on 1981 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several crops grown in the Willamette valley of western Oregon respond to applications of boron fertilizers. The acid, highly-leached soils of this area are naturally low in plant-available B. Application of B to the soil annually or at less frequent intervals is currently recommended, but the fate of applied B and the residual effect on plant growth has received little attention. In studying boron in these soils a more convenient and more accurate method for determining hot-water-soluble B based on the azomethine-H procedure was developed and adopted to replace the curcumin method. Substitution of 0.02 M CaC12 for distilled water for extraction of soil B resulted in clear, colorless solutions which permitted accurate colorimetric determination of B.A greenhouse experiment was established to investigate 1) the influence of soil properties on the mobility and plant-availability of B, 2) the magnitude of the loss of B from the surface soil by leaching, and 3) the residual effect of applied B on plant growth and the B supplying power of soils. Soil samples from sixteen locations representing five agriculturally important soil series were studied. The percentage of B from a 2.0 mg B /kg application recovered in 25 cm of leachate decreased as soil organic matter, clay, and free iron and aluminum oxide content increased. The results clearly indicated the importance of organic matter in reducing the mobility of B, and suggested that free Fe and Al oxides, and perhaps clay, may also be important. Soil acidity over a pH range of 5.4 to 7.5 did not influence the mobility of B. Dry matter yields for three cuttings of New Zealand white clover (Trifolium repens L.) were not significantly affected by B soil test level or B applied at planting. Plant tissue concentrations of B were high compared to field-grown forage legumes and, while these concentrations were affected by extractable soil B level or B application, the correlations between soil test level of B and plant content of B were low. A balance-sheet approach, where the amounts of leachate, plant, and extractable soil B were tabulated, indicated a B supplying power for the soils studied. All sixteen soils released B to leaching and cropping with minimal decreases in hot-water-soluble B content. When B was applied to the soils, only those higher in organic matter and/or free Fe and Al oxides tended to "fix" B in a form not recoverable by leaching, cropping and hot-water extraction. The capacity of the soils to maintain soluble B levels under cropping depended both on the individual soil and the amount of B present (i.e., check vs. B applied). The results are in agreement with a small body of literature suggesting the importance of intensity/capacity relationships in the availability of B to plants.

This book was released on 2002-05-31 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The economic significance of boron (B) in agriculture, horticulture, and forestry has been beyond dispute for several decades. Even in the last two decades, the areas where B deficiency limits plant production has grown with increased reports from China, south Asia and southeast Asia. The present volume is reflective of the growing awareness of the significance of low soil B with reports from Australia, Bangladesh, Brazil, north, central and southern China, India, Nepal, and the North West Frontier Province of Pakistan contained herein. Boron deficiency also continues to be a problem for crop yield and quality in areas where B deficiency has been known for some time, for example in Germany and the USA. The problem of low soil B is not limited to effects on field crop yield, with papers reporting on depressed wood yield and quality in timber trees (Lambert et al. ), and depressed fruit quality (Dong et al. ; Smith et al. : Zude et al. ) also appearing in the present volume. Globally, Shorrocks (1997)1 estimates that ?? tonnes of B fertiliser is applied annually in agriculture. The economic benefits from the use of B fertiliser have not been quantified but are clearly enormous. Paradoxically, the clear economic imperatives for using B fertiliser on low B soils are not matched by a similar clarity of understanding of the role and functions of B in plants.
