Fertigation. A Tool for Efficient Water and Nutrient ManagementFertigation. A Tool for Efficient Water and Nutrient Management. 2011. Kafkafi, U., and J. Tarchitzky. 140 p. ISBN 978-2-9523139-8-8
Published by IFA and IPI.

Sound water management has the potential to improve fertilizer/nutrient use efficiency. The introduction of well-tested, efficient fertilizer application through irrigation water or "fertigation" techniques could help turn vast areas of arid and semi-arid land in many parts of the world into farmland, as well as preventing water from being wasted in conventional irrigation systems. This book is a joint project of IFA and the International Potash Institute (IPI). It presents information relevant to soil-water-fertilizer interactions during fertigation. The authors have brought together various types of expertise on plant physiology, plant nutrition and irrigation, which are synthesized into practical knowledge related to fertigation in commercial field and greenhouse operations. Readers will find advice on selecting appropriate fertilizer products for fertigation of a number of field and horticultural crops. The suitability of some fertilizers for fertigation is explained from the point of view of the plant's physiological demand at different growth stages, the type of soil or growing medium, climatic conditions and irrigation water quality.

Fertilization of Selected Crops in Turkey (in Turkish)Önemli Kültür Bitkilerinin Gübrelenmesi. (Fertilization of Selected Crops in Turkey). 2010. Edited by Dr. Dilek Anaç, Ege University, Bornova, Turkey. 111 p. Turkish. ISBN 978-605-87957.

A requirement for higher yielding crops due to population growth has led to a greater use of inputs, which are often used in excess, to increase agricultural production. Precautions to control the excess use of fertilizers are very important not only for agricultural production, but for the environment as well as for the economy. Therefore, optimization in the nutrition of crops is essential in producing high quality healthy crops in an effort to obtain higher yields per unit of agricultural land.

Optimal and efficient use of fertilizers can only be achieved by understanding factors such as climate, soil properties, cropping period and the timing, amount and type of fertilizers used. Otherwise, soil fertility and yield quality may decrease, and the environment may be negatively affected.

This publication includes eleven chapters, each focusing on the growth requirements of a different crop: apricots, cherries, citrus, cotton, figs, maize, olives, thyme, greenhouse tomato, vineyards, and wheat, with an emphasis on climate, soil properties, nutrition as well as fertilization practices and recommendations. The authors of the chapters are all leading researchers from Ege University, Bornova; Celal Bayar University, Manisa; and the West Mediterranean Agricultural Research Institute, Antalya.

The publication will be useful for researchers, extension and agri-business technicians working in Turkey.

Fertilizing for High Yield and Quality: Soya in Latin America (in Spanish)IIP Boletín No. 20: Fertilizando Para Altos Rendimientos: Soja en Latinoamérica. (Fertilizing for High Yield and Quality: Soya in Latin America). 2011. 174 p. Spanish. ISBN 978-3-9523243-7-0. Authored by Dr. Ricardo Melgar, Estación Experimental de Pergamino, Buenos Aires, Instituto Nacional de Tecnología Agropecuaria (INTA), Argentina; Dr. Godofredo Vitti, Escuela Superior de Agricultura "Luiz Queiroz", Universidad de São Paulo, SP, Brasil; and Dr. Vinicius de Melo Benites, Centro Nacional de Investigación de Suelos, Río Verde, GO, Empresa Brasileira de Pesquisa Agropecuaria, EMBRAPA, Brasil.

The first edition of the IPI Crop Bulletin on Soya, written by Dr. Fauconnier, was published in 1986. Since this time, the area and productivity of soybean has dramatically increased, with Latin American producers playing a much more important role than before. The authors of this latest IPI publication in Spanish, Dr. R. Melgar (Argentina) and Drs. Vitti and de Melo Benites (Brazil), are well connected to this remarkable growth in their countries, and are well placed to outline soybean development in Latin America.

The publication includes four chapters, conclusions and color photos. In the opening chapter, the authors describe the economic importance of Soya in Latin America, including the development of the biofuel industry that uses soybean oil. The second chapter describes the general conditions required for the crop, climate, soils and potential across the Latin American region. In the third chapter, the role of each nutrient on the development and quality of the crop is outlined, and in the fourth chapter the various fertilization practices used in soybean production are discussed in detail, with a special focus on those applied in no-till systems.

Potassium for Quality and Yield Security in the Cultivation of Arable Crops (in Hungarian)Kálium - minőség és termésbiztonság a szántóföldi növények termesztésében. (Potassium for Quality and Yield Security in the Cultivation of Arable Crops). 2011. 16 p. István Terbe. Hungarian.

The brochure deals with the potassium demand and management of cereals, root and tuber crops, oil crops, tobacco, fodder crops and meadows and pastures. It briefly touches the topic of potassium in soils and gives some recommendations for fertilization of these crops.

Publications by the PDA

Potash Development Association - PDAThe Potash Development Association (PDA) is an independent organisation formed in 1984 to provide technical information and advice in the UK on soil fertility, plant nutrition and fertilizer use with particular emphasis on potash. See also www.pda.org.uk.

Note: Hard copies of PDA's publications are available only in the UK and Ireland.

Disappointing First Cut Yields due to Drought are no Reason to Neglect Potash and Sulphur.

June 2011. Yields of first cut grass have been lower than average in many parts of the UK. Pockets of the south west and N. Ireland aside, yields down by as much as 30% have been reported from Wales, Scotland and the midlands, north west and north east of England. Some grassland farmers may have delayed cutting to allow swards to bulk up, but with dry conditions encouraging early heading, this tends to exacerbate poor quality as stem elongation rushes on apace.
