The contentsof this volume representthe proceedings of the First International Symposium on Foliar Fertilization which was organizedby Schering AG Agro chemical Division's Special Fertilizer Group on 12-14 March 1985. The conference was attended by 130 participants from 35 countries . As a leadingcompany in the field offoliarfertilizers , ScheringAG organizedthis conferenceto gathercurrentknowledgeon foliarfertilization under various crop and environmental conditions.We believe thatthese Proceedings form a basis for a more relevantapproach to foliarfertilization in agriculture and horticulture and thattheysummarize the currentstateof our knowledgeon this highly efficient methodof fertilization. Besides the formalpresentation of invitedfull-length papers, shortcommunications were also invited for presentation. Most of theseshortcommunicationshave been kindly expanded by their authorsto fullpapers. The subject matterhas been arrangedin these Proceedings to obtain a bettersequence than was originally possible in theprogramme for technicalreasons .: Chapter1 dealswith "Fundamental aspectsof foliarfertilizat ion". Chapter2 deals with "Foliarfert ilizationunder arid and semi-arid conditions", Chapter 3 is devoted to "Foliar fertil ization under tropicalconditions",Chapter 4 deals with "Foliar fertilization in horticulture" , Chapter5 is devotedto "Foliarfertilization in cerealcultivation" and Chapter6 concludeswith "Foliarfertilization in differentcrops and count ries". It is appropriatethata substantialportion of these proceedings is devoted to practicalaspects of foliarfertilization thus recognizingthe fact that foliarfer tilizationhas gained an outstandingrole inagriculture and horticulture and will see even more inthe future. We express our special thanksto the chairmen of the various sessions who con tributedto the su ccess of thesymposium: Professors E. Malavolta,M. Fregoni , T. Kudrev, H. -W. Doring, D. jelenic and Dr. V. Szirtes .
