Traditionally, expensive commercial fertilizers are used to correct  soil nitrogen deficiencies. Indeed, 50% of the increase in rice yields  after World War II can be attributed to increased fertilizer nitrogen  use. Although an increased rate of fertilizer nitrogen application has  been advocated to meet the growing demand for food, it is unrealistic  to advise the farmers to apply fertilizers they could hardly afford,  and whose prices are likely to escalate in the years ahead. In  addition, when they are not applied judiciously there are problems of  environmental pollution as plants are capable of taking up only a  relatively small portion of the applied nitrogen, a substantial amount  being lost through various chemical and biological processes. The  exploitation of cheaper alternatives or supplements to fertilizers  have therefore gained much interest in recent years.\u003cbr\u003e  Our increased interest in biological nitrogen fixation as a supplement  or alternative to nitrogen fertilizers led to the convening of a  consultants' meeting on `The Role of Isotopes in Studies on Nitrogen  Fixation and Nitrogen Cycling by Blue-Green Algae and the  \u003cem\u003eA\u003c\/em\u003e\u003cem\u003ezolla-Anabaena azollae\u003c\/em\u003e Association', in Vienna from  11--15 October 1982. The consultants' group recommended that the Joint  FAI\/IAEA Division of Nuclear Techniques in Food and Agriculture embark  on a coordinated research programme in this field and that initial  emphasis should be placed on \u003cem\u003eAzolla-Anabaena\u003c\/em\u003e symbiosis. As a  result, such a programme was initiated in 1984, which was concluded in  1989. The results and conclusions reported here are those that were  generated during the five years of its operation.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1993-03-31\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9780792322740\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-94-011-1681-7\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 148\u003c\/p\u003e ","brand":"Springer Netherlands","offers":[{"title":"Default Title","offer_id":46311913783436,"sku":"9780792322740","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9780792322740.jpg?v=1771514410","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9780792322740","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
