Book excerpt: Soil acidity is one of the major problems for crop production in many parts of the world. Poor crop productivity and soil fertility in acid soils are mainly due to a combination of aluminum and manganese toxicities and nutrient deficiencies (mainly deficiencies in P, Ca, Mg and K). Among these problems, aluminum toxicity is one of the major factors limiting crop production in acidic soils. Aluminum, the third most abundant metal in the earth's crust, poses a serious threat to crop productivity in acidic soils. It covers approximately 40 per cent area of the earth's arable land (Ma et al. 2011). Aluminum exists in nature as mononuclear, polynuclear and also as low molecular weight complexes. However, mononuclear is considered as highly toxic as compared to other forms (Taylor 1991, Kinraide 1993). When the soil pH drops below 5.0, aluminum is solubilized as the phytotoxic Al3+ species from non-toxic aluminum silicates and oxides (Lindsay 1979). The mobility of aluminum increases sharply with the reduction in the availability of exchangeable cations such as Ca2+, Mg2+ and K+ (Parker et al. 1989). The high mobility of aluminum is seen in Kaolinite rich soils at pH levels as high as 5.5 (Alam and Adams 1979, Foy 1974. Roy et al. 1988). The toxicity will be acute at pH 4.1 in soils than at pH 4.5. However, in nutrient solutions, aluminum toxicity is more severe at pH 4.5 than at 4.0 due to the formation of A1(OH)2+ ions, which are more toxic than A13+ itself (Moore 1974).

Download or read book Plant Soil Interactions at Low pH Principles and Management written by R.A. Date and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding of plant-soil interactions in acid soils is important for improved food production in many parts of the world. The context of the book touches on basic and applied aspects of the physics, chemistry and biology of acid soils and their effect on growth of plants. It contains a large section on management of acid soils for plant (food) production and on socioeconomic aspects of management of acid soils. This is important because a large portion of the world's acid soils occurs in less developed countries. Plant-Soil Interactions at Low pH: Principles and Management contains a substantial number of papers, including nine invited reviews, presented at the Third International Symposium of Plant-Soil Interactions at Low pH. The major themes include chemistry and physics of acid soils, microbial and faunal activity in acid soils, mechanisms of acid tolerance of plants, selection and breeding of acid-tolerant plants, diagnosis and correction of acid soil infertility, socioeconomic aspects of acid soil management and management systems for agriculture, horticulture and forestry on acid soils.
Download or read book Soil Acidity in Oregon written by and published by . This book was released on 2013 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quick facts: Nitrogen (N) fertilizer application is the predominant management practice that causes soil acidification (declining soil pH). Nitrogen fertilizers that supply N only in the ammonium (NH4) form are the most acidifying (page 6). Crops and varieties differ in tolerance to soil acidity. Recommended minimum pH values for a wide range of crops are listed in Table 9 (pages 18-19). Lime is recommended to maintain soil pH above recommended values. Increased soil acidity can injure plants by a number of mechanisms, including: [1] Increasing the amount of soluble aluminum (Al) and manganese (Mn) in soil to toxic levels (pages 9-11) [2] Reducing the amount of plant-available phosphorus (P), calcium (Ca), and molybdenum (Mo) (pages 11-13)Some legumes are very sensitive to soil acidity because soil acidity inhibits N fixation by bacteria of the genus Rhizobium. These bacteria require high soil levels of Ca and Mo, which are limited at low pH. Under acidic soil conditions, legume roots may have few nodules or their nodules may be ineffective at N fixation (page 13). Information on pH and weed management (pages 20-21) and on soil pH monitoring (pages 7 and 15) is also contained in this publication. Neutralizing soil acidity with lime is discussed in companion publications (page 2).
