Available in PDF, EPUB and Kindle. Book excerpt: Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

Available in PDF, EPUB and Kindle. Book excerpt: The low solubility of many rock phosphate (RP) around the world is the main cause of their ineffectiveness when applied to soil as a source of P for crops. The low solubility decreases their value as P fertilizers and prevents their widespread use, especially for high P demanding crops. One method proposed to enhance RP solubility is to add sulfur (S) as an amendment. The oxidation of S to H2SO4 in the soil results in dissolution of the applied RP. This study tested three Brazilian RP sources (Araxa, Catalao, and Patos de Minas) mixed with S at a ratio of 5:1 (RP:S). The application of the RP-S mixtures proved to be a promising alternative method for increasing RP solubility and thus their effectiveness as P sources. The soil pH decreased proportionally to increasing rates of RP-S application. The NaHCO3 extractable soil P increased as a consequence of increased soil acidefication. The ryegrass growth, P uptake, plant P concentration and P recovered from RP sources were enhanced only when S was mixed with the RPs. On the other hand, when RP sources were applied directly without S, the available soil P as measured by NaHCO3 extraction was depleted with time regardless of source or rate of RP. The inefficiency of the directly applied RP sources to supply adequate P was evidenced by less plant growth than applied with S. Also, in addition to this inadequate supply of for plant assimilation, the directly applied RP sources failed to develop a residual reserve of available P in the soil, even at very high application ...
