Soil properties such as pH, redox potential, organic matter content, nutrient interactions, the type of plant or variety, and environmental factors, such as soil water content, temperature and light, greatly influence the likelihood that a plant will exhibit micronutrient-deficiency or -toxicity symptoms. Changes in the environment often have a greater effect on micronutrient than on macro nutrient nutrition of plants. This chapter emphasizes advances in knowledge since Lucas and Knezek's (1972) review in the first edition of this book. In addition, greater emphasis than is customary will be placed on the role of the environment on micronutrient nutrition. Other general references that contain material on this topic are available (Adriano, 1986; Bergmann, 1988; Marschner, 1986; Mengel & Kirkby, 1987; Weber, 1971; and Wild, 1988). Some excellent reference sources include the specific contributions of Keren and Bingham (1985) and Fleming (1980) on B, of Loneragan et al. (1981) on Cu, of Jones (1982, 1984, 1986, and 1988) on Fe, of Graham et al. (1988) on Mn, of Gupta and Lipsett (1981) on Mo, and of Adriano (1986) on Zn. The comprehensive study of Sillanpaa (1982) provides much useful information concerning micronutrient uptake by plants and selected soil properties.","PeriodicalId":405171,"journal":{"name":"Micronutrients in Agriculture","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127016444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advances in technologies and methods associated with diverse areas, such as membrane isolation and the subsequent solubilization of membrane transport proteins from these membranes and their reconstitution into artificial liposomes, various microelectrode techniques, including ion-selective microelectrodes, extracellular vibrating microelectrodes, and patch clamp methodology, and most recently, molecular biology investigations of transport proteins, have advanced our understanding of molecular and cellular aspects of some ion transport systems. However, research in the areas of plant micronutrient uptake and long-distance transport has not progressed as rapidly for two reasons. First, there has simply been less research conducted in the area of micronutrient transport, which is the result, primarily, of a lack of proper research funding for this important area of plant nutrition. Since 1972, the bulk of the work in this area has focused on Fe absorption into plant cells, which indeed, has resulted in a significant increase in our understanding of Fe transport and nutrition. Considerably fewer investigations have been conducted into the transport of the other micronutrients and, in some cases, Mn and Mo transport in particular, little new research has been carried out over the past 15 yr. Second, research into micronutrient cation (Fe H , Cu2+ , Zn2+ , Mn2+, and Ni 2+) transport has been complicated by the chemical nature of these reactive species; that is, the tendency of these cations to form metal-organic complexes of varying stability, size, and charge (Tiffin, 1972). Therefore, it is not sufficient (or safe) to assume that the mechanisms of macronutrient and micronutrient transport differ only in the lower requirements of the micronutrient transport systems for substrate, and that all that can be learned from studying macronutrient transport systems can be extrapolated directly to the micronutrients. Certainly, many of the general aspects of ion absorption related to thermodynamic driving forces and the structure/function of","PeriodicalId":405171,"journal":{"name":"Micronutrients in Agriculture","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122100871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, at present, only 17 are regarded as essential for all higher plants. These include the nine macronutrients, C, H, 0, N, K, Ca, Mg, P, and S, which typically occur in the plant dry matter at concentrations ~ 0.1 010, and the seven micronutrients, CI, Fe, B, Mn, Zn, Cu, and Mo. In addition, Co is essential for symbiotic N fixation in legumes and some other species. The term ultra-micronutrient has been proposed (Nicholas, 1961) for elements such as Mo and Co, which are needed in particularly small quantities. However, positive effects of many other elements on plant growth have been reported over the years. This prompts researchers to question what constitutes essentiality (and nonessentiality), whether all the essential elements have been discovered, and how elements that appear to have beneficial effects on plant growth, yet have not been shown to conform with our definition of an essential element should be regarded. This chapter is intended to explore these questions and to comment on some of the elements in the latter category.","PeriodicalId":405171,"journal":{"name":"Micronutrients in Agriculture","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133759877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
