The International Potash Institute (IPI) is celebrating its 60th anniversary (1952-2012). For many decades, our agronomists and soil scientists have carried the message of “Balanced Fertilization”, demonstrating and disseminating the role of potash in yield performance and quality, in stress tolerance and in bringing more value to the farmer.
IPI was founded by German and French potash producers almost 100 years after the discovery of potash-bearing salts in Staßfurt, Germany. The aim of the Institute was to “foster the application of scientific and practical methods for the amelioration of the soil in general and the use of fertilizers, especially of potash”. Its headquarters was located in Bern, the capital of Switzerland, and after a few months, a Scientific Board with scientists from 16 European countries was established to provide IPI with the necessary scientific guidance.

With Switzerland hosting the Institute, two distinguished politicians - Paul Chaudet and Nello Celio - who had both served as President of the Swiss Confederation, led the Institute till the 90s. Alexander von Peter, IPI Director from 1970 to 1991 reflects that “one of the assets the Institute had during these days was the open and productive exchange of views among the agronomists of the member companies, which allowed the Institute to establish missions in Africa, Asia, Latin America and more.”

In 1957, after five years of IPI operation, the first new member joined the German and French founders (Dead Sea Works Ltd., a potash producer in Israel) soon followed by other potash producers in Spain, UK, GDR, USSR and Jordan. With this expansion, the Institute became the scientific hub for potash producers across Europe and the Middle East.
Celebrating IPI’s 60th anniversary provides an excellent opportunity to hear about the Institute’s past activities from previous members and leaders of IPI. During the last few months (early in 2012) I had an opportunity to meet with some of them whilst traveling to Germany and Israel.

Prof. Dr. Iossif Bogdevitch.
Ever since his meeting Dr. Alexander von Peter in 1974, Prof. Iossif Bogdevitch from Belarus has been closely involved in IPI’s work. In 1990 he was instrumental in organizing the first IPI symposium in the Former Soviet Union on “Development of K-Fertilizer Recommendations”. The conference was held in Soligorsk, the city closest to the large potash deposits from which JSC Belaruskali, an IPI member, produces its potash. In the 1990s, Prof. Bogdevitch joined the IPI Scientific Committee, where he, and other leading scientists, influenced and provided valuable guidance on IPI’s activities. In 1998, he became the IPI coordinator for Belarus, the Baltic States and Ukraine which, he says, was “the most satisfying time in my professional life.”

Abraham Cohen and Meir Bazelet are veteran IPI coordinators, working for more than 30 years as coordinators and members of the IPI Technical Secretariat. A. Cohen joined IPI in 1971. After a few years, he was posted to IPI missions in South Africa and Latin America as an IPI coordinator, before returning to work at the head office in Bern. M. Bazelet joined IPI as a coordinator for Turkey in 1966. Later he held coordination positions in China, South Africa, Argentina, amongst others. Both veteran coordinators admit that satisfaction came predominantly from the opportunity to assist in developing sound research work on K nutrition in countries with local scientists, many of whom they stayed in contact with over the years.
Dr. Alexander von Peter served as IPI Director at the Bern headquarters from 1970 to 1992. I met him at his home in Heidelberg, and we greatly enjoyed reviewing his rich history with IPI. An economist by training, Dr. A. von Peter was always very conscious of the economical use of potash fertilizers. He recalls that the technical meetings at IPI, with so many agronomists from the member companies, always provided fruitful brainstorming. During his time as director, IPI changed its focus in activities and moved from mostly organizing symposia to active coordination in regions, which assumed that an impact in this field of operation could be gained. In 1992, after more than 20 years living in Bern, he retired and returned to his home in Heidelberg.

Dr. Adolf Krauss served as IPI Director from 1994 to 2004. In 2002, at IPI’s 50th Jubilee Symposium, he wrote that, “very early on, IPI also looked beyond Europe and established missions around the world, either on its own or in collaboration with what is now the Potash and Phosphate Institute, PPI/PPIC headquartered in the USA. The most comprehensive mission was the POTASCHEME in India (1957-1962), which had both expatriates and a large number of local staff. Other missions were founded in subsequent years in Argentina, Brazil, Peru, Uruguay, East Africa, South Africa, former Rhodesia, Hong Kong, Iran, Japan, Korea, Singapore, Taiwan, and in Montpellier, France for the Mediterranean region.” During his tenure, IPI focused strongly on the term “Balanced Fertilization”. Data presented in Fig. 1 shows how consumption of nitrogen fertilizers expanded in comparison to P and K, leading to severe nutrient imbalances in many regions, with ill-consequences on productivity, quality of products, declining soil fertility and environmental degradation.
Mr. Erich Wyss, former IPI President served the Institute for almost 20 years (1991-2009). This period was fundamental in forming the new identity of IPI as a result of the adjustments made at the end of the 80s following the demise of the Former Soviet Union. Mr. Wyss provided valued leadership during changing times and allowed the Institute to maintain and increase its scientific activities worldwide. He also participated in various symposia held in parts of the world, and inaugurated the IPI Golden Jubilee Congress in Basel, “Feed the Soil to Feed the People - The Role of Potash in Sustainable Agriculture”, with many of IPI’s research partners attending. The first Five-Year Plan (2009-2013) for IPI was completed during his service.

Prof. Dr. Christian Brückner joined IPI as President in 2009. With strong support from its members, Prof. Brückner provides critical guidance for the Association as we face new challenges and opportunities. IPI’s current portfolio of activities spans nine regions with research and dissemination projects led by six coordinators (see photo), overseen by the head office in Horgen, near Zurich. All coordinators are experienced field agronomists with IPI member companies. Nominated by the General Assembly of the IPI Members, IPI coordinators operate on a long-term basis in regions worldwide in accordance with the strategic framework of the Five-Year Plan.
Early days for potash production at Dead Sea Works, Israel.
In the 1960s and 1970s, IPI invested heavily in producing scientific literature on the role of K in agriculture. With its first proceedings published in 1954, IPI has continued to publish new proceedings every year up to the present. All these publications have been scanned and are now available on the IPI website.
For almost 40 years between 1956 and 1995, IPI published the Potash Review, a collection of more than 1,000 themed scientific papers, with many of the papers dealing with potash use in international agriculture. These legacy documents were also recently made available on the IPI website, and can be searched by title, author, year and theme. Prof. (Emeritus) Uzi Kafkafi, a veteran of IPI’s Scientific Committee said, “this transformation of the practical reports, published in Potash Review for over 40 years, is once again bringing to life the basic agronomical knowledge accumulated over almost a century of advanced agricultural research. Basic information for agronomists and growers can now be retrieved quickly and accurately with the proper references. In this new format, Potash Review replaces old plant nutrition books that are no longer easily accessible. In these modern times where most agricultural research centers are concentrating on genetic research, such basic agronomic knowledge is neglected and the current generation of students has no real contact with the old accumulated wisdom. IPI deserves deep appreciation for the resurrection of this real basic knowledge in fertilizers and plant nutrition that otherwise would have been lost forever.”
In 2006 IPI initiated a new electronic newsletter (e-ifc), sent out quarterly to more than 2,000 email recipients. In each edition, three to four research items and a collation of events, new publications and an update of recently published papers with relevance to potassium fertilization are included. Edited by Dr. Ernest A. Kirkby, the newsletter provides scientific reports from IPI research projects in more than 20 countries spanning across Latin America, Europe, Africa and Asia. More than 80 research papers have already been published, and each year more are added.
Providing “crop specific” information has been achieved by inviting eminent scientists to compile data on nutrient management for a specific crop. The first Crop Bulletin published by IPI in 1974 was on wheat, by Dr. G. Kemmler from the Büntehof Agricultural Research Center Station in Germany. More than 30 crop bulletins are now available, covering field crops, fruit and vegetables, and fiber crops, amongst others, with the Sugarcane Crop Bulletin to be released in the near future.
The need to highlight a specific issue such as fertigation, or potassium requirements of crops, led to the evolution of another series of publications known as “Research Topics”, produced every two years, to which IPI invites prominent scientists to contribute on relevant topics.

IPI has not only been involved in creating scientific findings, but also in disseminating them. Recent developments in information technology provide enormous opportunities for developing new, innovative dissemination tools. IPI is developing several Apps which will run on Apple and Android systems to allow users to: view a set of pictures demonstrating the effect of potash on a large variety of crops and illustrating typical deficiency systems (K gallery); read and search through the IPI e-newsletter (e-ifc); or calculate nutrient removal rates from various crops. The excellent resolution, search and sharing tools makes these Apps on either Apple or Android smart phones and tablets very useful to smallholder farmers, extension experts as well as researchers.

Worldwide, more than fifty ongoing field experiments and demonstration plots are executed each year, together with seminars, workshops and farmers’ field days. International symposia are regularly conducted in countries where we operate, to demonstrate the essential role of potassium in optimized crop nutrition to various target audiences. IPI makes a major investment in reaching out to farmers, their suppliers and advisors and believes in field-level promotion and outreach to farmers, as well as in fundamental and applied research. We also work hand-in-hand with organizations that include extension services, universities and those willing to take part in farmers’ gatherings, field days, open seminars, training courses and other learning-related activities.

The first deliveries of potash fertilizer date back to 1880 (Table 1), with high growth rates recorded during 1880-1910 when we know that some deliveries were already crossing the Atlantic from Europe to the East coast of the US. In 1935, more than 60 percent of global potash sold originated from Germany, followed by supplies from the potash mines in France, Russia, Spain, Poland, US and Israel (Fig. 2).
The potash market (and all other agri inputs) recovered after the Second World War and in 1954, total deliveries were more than 5 million mt K2O. From 1954 to 1961 (this period is not covered by the FAOSTAT database) growth was maintained at high level, and in 1961, total deliveries reached more than 9 million mt K2O (FAOSTAT).

From the FAOSTAT database which also covers crop and nutrient data from 1961 till today, and with supplementary data from the International Fertilizer Association (IFA), various developments can be assessed:

The vision of the IPI founders in 1952 is still valid today. Our principles of cooperation have lasted through many years in many regions and crises as farmers, and those who assist them, value a constant flow of science and partnerships to enable progress. Römheld and Kirkby (2010) describe the needs and prospects for research on potassium, and highlight the need for advanced and effective dissemination of knowledge. The rapid development of ICT provides many new tools to allow much faster and more effective dissemination of practical knowledge to farmers using smartphones and web connections. We, at IPI, believe that advanced dissemination is one of the first tools necessary for increasing agricultural productivity.
Römheld and Kirkby (2010) summarized and highlighted the needs for future potassium research:
Other fields which require future research include:
The practice of intensive fertilization to support massive food production for an increasing global population with higher dietary requirements has a short history. During the last 50 years, food production has hugely increased. However, consumption of nutrients N, P and K has been much skewed towards N, causing potassium depletion in soils and reduction in yields in many regions Therefore, to enable closing yield gaps and allow for a much higher productivity in many regions, a significant increase in K fertilization is required (Mueller et al., 2012).
Meeting the future demand for food is a huge challenge. By 2050, food production needs to have doubled, but achieving this will be very different to the past, depending on crops with a much higher demand for K than cereals, such as oil and sugar crops, fruits and vegetables, and roots and tubers. Considering the need for additional intensification, as well as environmental stewardship, soil fertility management and sustainable production, the term “Balanced Fertilization” should be revived, as one of the simplest to implement yet sound and appropriate measures farmers need to use in the future.
