Chapter 4. The fertilizer sector


Fertilizer supplies

The production of fertilizers started in Iran in 1945, in a small factory near the city of Karaj. Within ten years it had reached a production potential of around 60 tonnes. The main products were single super phosphate (SSP), thermo phosphate, bone powder and potassium nitrate. It was in 1955 that 176 tonnes of mineral fertilizers were imported into the country by the government for the first time. Along with this importation, the private sector also purchased 305 tonnes of mineral fertilizer. Later, the sugar industry also started to import on its own behalf. In the 1960s there were more than 17 different types of mineral fertilizers used in the country including five different N-fertilizers, four P-fertilizers, three types of Kfertilizers and more than five varieties of mixed fertilizers.

In the 1970s, with the establishment of Razi Petrochemical Industries, the government banned imports by the private sector. This company produced mainly triple superphosphate (TSP), diammonium phosphate (DAP) and ammonium sulphate (AS).

Production of fertilizers

The National Petrochemical Company manufactures a total of 1.8 million tonnes of urea and ammonium phosphates annually. After the revolution, at the initiative of Soil and Water Research Institute (SWRI) and as a result of soil testing, it became evident that a comprehensive plan for developing fertilizer production in the country was necessary. As a result, production by the private sector of fertilizers, including micronutrients, was promoted. This has led to the manufacture of a range of fertilizers since 1995. Over two hundred small manufacturers in different parts of Iran have been issued with permits to produce in total about two million tonnes of NPK compound fertilizers. Since 1995 many manufacturers have begun to produce micronutrient fertilizers such as zinc sulphate, copper sulphate, manganese sulphate, iron sulphate and boric acid. Several plants have recently begun the manufacture of superphosphate fertilizers (SSP or TSP) in locations where high-grade rock phosphates are plentiful. Several production units are engaged in making various types of sulphur materials such as sulphur coated urea, whose local name is Sari fertilizer, etc.

The 200 private fertilizer manufacturing units employ some 40 000 workers, directly or indirectly. However, the total number of plants that have good production capability, with an annual production capacity of a hundred thousand tonnes of quality fertilizers, does not exceed five in all, the others being small-scale producers. Total production from the sector reaches only about 0.5 million tonnes annually. Due to unstable demand and purchasing programmes, many manufacturers are facing problems with production and schedules.

In view of these problems, in 2001 the Organization of Professional Fertilizer Producers (OPFP) was established at the initiative of some active manufacturers. The objective is to coordinate and direct the members' activities so as to meet the demand quantitatively and qualitatively. At present some 80 percent of the manufacturers claim membership of the organization.

The total production of mineral fertilizers between April and September 2004 by all production units amounted to 1 314 thousand tonnes (Table 8). Of this total, 979 thousand tonnes were produced by the state-owned industries, a reduction of 5 percent compared with last year. The private sector produced 336 thousand tonnes, an increase of 28 percent in comparison with last year.

In 2004, 57 percent of mineral fertilizers, 80 percent of pesticides, and 100 percent of seeds were produced nationally, by both the public and private sectors.

FIGURE 8
Trends in fertilizer consumption changes during the past four decades

The improvements in fertilizer use are recorded in Table 10.

The development in recent years of the importation and consumption of potassium fertilizers, starting from almost zero, may be noted.

The predicted fertilizer use in 2004/05 is shown in Table 11.

Demand and supply

Domestic fertilizer production cannot meet the total demand (Table 12). Additional supplies are provided by imports by the private sector. For example, in the period from April to September 2004, imports by the private sector amounted to 275 thousand tonnes, of which 198 thousand tonnes were compound fertilizers and 52 thousand tonnes phosphate fertilizers. Based on the research carried out, the annual fertilizer needs in the country for the next 15 years is calculated and shown in Table 13.

1 Excluding organic and biological fertilizers, estimated annual use about 500 000 tonnes.

Fertilizer use by crop

In Iran there are no reliable records of the amount of fertilizer used by each individual crop, apart from wheat. The total amount of fertilizer used by province is known. Also the amount of fertilizer used on wheat is known. Based on this information, estimates of fertilizer use in 2001/02 on wheat, orchards and other crops are given in Table 14.
