IPI Bulletin No. 4 on Fertilizing for high yield Citrus

* IPI Bulletin No. 4 on "Fertilizing for high yield Citrus" has been thoroughly revised by Y.Erner, A.Cohen and H.Magen. Total production of citrus exceeds that of all other fruit including deciduous kinds and banana. This Bulletin, dealing with a crop of such economic importance, offers guidance to citrus growers and their advisors on how to achieve best results in their plantations. The Bulletin discusses the crop's requirements as regards climate, soil, water and crop management. Nutrient requirements are covered under the headings of the major and minor nutrients. The effects of nutrient deficiency are discussed, with coloured plates showing visual symptoms, and measures for their correction are described. The determination of fertilizer requirements using sophisticated methods of leaf analysis is covered in some detail. Finally, practical fertilizer recommendations from several countries are described. It is hoped that, as well as providing a practical guide for growers, the Bulletin may also serve as a reference for further research.
