Fertilizer, How Much Is Necessary?

Kwon Tae-jin

BACKGROUND

     North Korea has been experiencing an acute food crisis due to a series of natural disasters and the lack of agricultural resources. In response, the international community including South Korea has provided aid to help resolve the chronic food shortages. However, there is a suspicion that North Korea has appropriated the aid for military purposes.
     South Korea was asked to help North Korea's agricultural development, by providing agricultural resources such as fertilizer to ease the aggravating food shortages there. In response, the South Korean government set a policy which would provide the North with aid for agricultural development as well as for humanitarian purposes. In a ceremony commemorating the founding of Korea Broadcasting System (KBS), held on March 3, 1999, President Kim Dae-jung stated that the fertilizer aid to the North should be discussed at the governmental level based on the principle of reciprocity. He added, however, that a small amount of fertilizer for humanitarian purposes would be delivered to the North through the Red Cross.
     Fertilizer was chosen as a form of aid because it was believed that it could contribute greatly to increase agricultural productivity. During the 1970s and 80s, North Korea's agriculture experienced great success as a result of high-density planting and extensive use of fertilizers. The methods proved to be detrimental, however, to the natural balance of the soil and subsequently brought about negative side-effects such as a deterioration in soil fertility. It has now become almost impossible to restore the devastated soil in the short term. Furthermore, it would be very impractical for North Korea to pursue a fundamental solution to its agricultural problems without addressing the immediate problem of its hunger-stricken people. North Korea has recently transformed its uniform maize priority cropping system, prevalent throughout much of the country, to growing more potatoes and to diversifying the types of crops grown.
     International organizations have suggested that North Korea decrease planting density and use less fertilizer in order to restore soil balance. Following that advice is a positive step for the North from a long-term perspective. The reality of the present food crisis, however, gives North Korea no choice but to use more fertilizer in order to increase food production. One does not have to perform a complicated mathematical analysis to understand the economic importance of fertilizers to North Korea. If North Korea were currently using less than 20% of the amount of fertilizer needed, the increased use of fertilizer could bring about an instant and effective outcome whose economic benefits would outweigh those of other inputs. This explains why the North desperately wants fertilizer aid.

 

THE NEED FOR FERTILIZER AID TO THE NORTH

     In return for fertilizer aid to the North, the South Korean government expected cooperation, such as creation of exchange centers, where North Koreans and South Koreans could mail and receive letters from one another, and a reunion center for separated families. The North, on the other hand, refused to cooperate. Furthermore, agricultural cooperation between South and North Korea came to a halt because the North refused to abide by the principle of reciprocity and insisted on unilateral aid from the South.
     What is more, there is no sign that the North Korean food crisis will improve this year. Although the level of food production increased in 1998 compared to that of the previous year, it is still not high enough to guarantee sufficient food for the North Korean people to survive, if one takes into account the amount of fodder needed for animals, seeds, and the natural diminution of agricultural return. Consequently, the North Korean people will continue to suffer from famine unless North Korea procures an adequate supply fertilizer in 1999.
     Almost half of the nutrients needed for growing crops must be provided during the early stage of planting through application of base manure, and with the farming season approaching, the need for fertilizer aid can no longer be postponed. The active farming season in North Korea usually begins at the end of April. Considering the time needed for distribution of fertilizer, fertilizer aid to North Korea should be received by mid-April. Without North Korea's formal request, however, direct fertilizer aid by the South Korean government can hardly be justified. Instead, the South Korean government opted to provide North Korea with fertilizers through the South Korean Red Cross, in the form of unconditional humanitarian aid.
     On March 10, the South Korean government and the ruling party decided to provide fertilizer aid to North Korea through the South Korean Red Cross as well as to support the World Food Programme (WFP) in its efforts to help North Korea's agricultural development and resolve its food crisis. As a first step, 50 thousand tons1) of fertilizer was scheduled to be sent to North Korea through the South Korean Red Cross before the end of April. The delivery procedure was to be decided jointly by the South and North Korean Red Cross. In a special press conference on March 11, the South Korean Red Cross appealed to the public, to donate funds to be used towards the purchase of fertilizer for the North. The Red Cross also appealed to the South Korean government to provide the North with fertilizer aid in the form of nation-wide humanitarian aid. In response to the campaign, held March 15 to June 15, the South delivered a total of 55 thousand tons of fertilizer aid (worth about 17.2 billion dollars) to the North as of last March. 29.
     The South Korean government promised to provide the North with 200 thousand tons of fertilizer (worth about 50 billion dollars) based the so-called "inside agreement" on June 3, in Beijing, and delivered 100 thousand tons (worth about 25 billion dollars) to the North in June, 1999. The shipment included 45 thousand tons of compound fertilizer, 32 thousand tons of urea, 10 thousand tons of ammonium sulfate, and 13 thousand tons of fused phosphate.

Fertilizer Production in the North2)

     During the 1940s, North Korea produced 480 thousand tons of fertilizers a year. Since then, the North has increased its production of fertilizers through expanding or constructing plants such as Hungnam Factory (350 thousand tons of ammonium nitrate lime, 400 thousand tons of ammonium sulfate, 180 thousand tons of urea, 400 thousand tons of super phosphate, etc.), lime nitrogen fertilizer plant in Sunchon (expanded from Sambo chemical plant in 1967), The phosphate plant in Haeju refinery (expanded in 1971, 1975, and 1980), Nampo refinery (expanded in 1954, 1958, 1962, and 1984), and Chongnyun and Chongsu chemical factories. By the 1960s, North Korea had moved ahead the South in fertilizer productivity. (see table 1)

     Fertilizers produced in North Korea, however, have a relatively low concentration of active ingredients. They are so inefficient that the South had already stopped producing many of them. Nevertheless, the North produces nitrogenous fertilizers such as lime nitrogen (contains 19% nitrogen), super phosphate (29% phosphoric acid), ammonium nitrate (19% nitrogen), and ammonium chloride (25% nitrogen). Compared with urea (46% nitrogen) produced in the South, the concentration of nitrogenous ingredient in nitrogen-based fertilizers of the North is less than half that of the South. Moreover, the technology used to produce fertilizer in the North is out of date and the facilities producing compound fertilizer are few. As a result, it was not until 1990 that the North was able to produce potassium-based fertilizers.
     It is reported that the North produced a total of 4.28 million tons of chemical fertilizers in 1995; 650 thousand tons of urea, 400 thousand tons of ammonium sulfate, 350 thousand tons of ammonium nitrate lime, 370 thousand tons of lime nitrogen, 1.4 million tons of super phosphate, 400 thousand tons of fused phosphate, 510 thousand tons of potassium, and 200 thousand tons of ammonium chloride, etc. The specific breakdown of chemical fertilizers produced by the North includes 1.73 million tons of nitrogen, 1.78 million tons of phosphorus, and 170 thousand tons of potash. However, it is estimated that the real production of fertilizers will be 3.68 million tons because of worn-out facilities, and in terms of ingredient concentration, it will only total one million tons, half of that produced in the South. Because of the lack of equipment as well as resource and energy constraints, North Korea stopped operating Namhung Youth Factory and Aoji chemical plant for nitrogen-based fertilizers. Moreover, only part of Hungnam Factory is now in operation.3)
     Although Hungnam fertilizer cooperative plant once produced ammonia with coal as its main raw material, it stopped production it because of the damages incurred in the last flood. Furthermore, because of the dearth and the expense of electricity, those fertilizer plants made almost no profit.
     If the North would increase its supply of electricity and replace coal with bunker C oil, it could produce more nitrogen-based fertilizer.4)
     The North's capacity to produce nitrogen-based fertilizer amounts to a total of 400 thousand tons (in terms of ingredient); 216 thousand tons in Namhung plant, 141 thousand tons in Hungnam, and 34.5 thousand tons in Aoji. In actuality, only 37 thousand tons of nitrogenous fertilizer and 10 thousand tons of phosphate were produced in 1998.
     The North has recently encouraged farmers to produce and use, their own fertilizers such as liquid fertilizer, manure fertilizer, soil-mixed organic fertilizer, peat, to make up for the shortage in chemical fertilizers. It is estimated that the North could produce 50 thousand tons of complex microbial fertilizer and soil-mixed organic fertilizer per year. This is a type of organic fertilizer made up of humus soil sprinkled with urine to which urea is added and fermented at 40‘® for a week. Complex microbial fertilizer, on the other hand, is created with useful microbes extracted from the soil and fermented with various organic materials such as straw, chaff, sawdust, charcoal, and agricultural or fishery wastes. Last year, Chongryun--General Association of Korean Residents in Japan, a pro-Pyongyang organization--helped the North construct about 100 complex microbial fertilizer plants. This year the North launched a project for self-produced fertilizer as a national business in order to overcome chemical fertilizer shortages. Thus, the North Korean authority has assigned targets for fertilizer production to plants in urban areas, state farms and cooperative farms as well as to individual farms.

 

MEETING THE DEMAND FOR FERTILIZER

Demand for Fertilizer

     In the North, it is the cooperative farms that decide how much fertilizer should be used. In other words, the cooperative farms make their preliminary estimate on how much fertilizer is needed at farms before the planting season and submit a report to the county farm management committee. The county farm management committee then reports it to the province rural economic management committee. In the final stage, the Ministry of Food Administration decides on the total amount of annual fertilizer needed, based on the province rural economic management committee's report. The Ministry of Food Administration makes its decision taking into account the production levels of fertilizer plants and the amount of fertilizer imported. Furthermore, the Ministry of Food Administration gives production orders to each fertilizer plant, as well as overseeing the distribution of fertilizer. The fertilizer is usually first distributed to the Ministry of Food Administration, the province rural economic management committees, and the county farm management committees before it is distributed to the cooperative farms. Generally, they are responsible for transporting the allotted fertilizer to their own farms.
     In the 1980s, the North experienced a severe imbalance among the three major ingredients of fertilizers in terms of their NPK ratio; using nitrogen as a standard (1.0), the NPK ratio of nitrogen (N), phosphorus (P), and potash (K) was 1.0 : 0.22 : 0.11. On the other hand, NPK ration among the three ingredients in the South was 1.0 : 0.46 : 0.50. While the average amount of fertilization in the North was 343.5kg/ha, that in the South was 363.9kg/ha from 1982 till 1987.5)
     According to a report made by the North, the amount of fertilizer used in terms of real weight had increased from 260 (131kg/ha) in 1949, to 215 (113kg/ha) in 1956, to 307 (160kg/ha) in 1960, to 599 (300kg/ha) in 1963, and to 982 thousand tons (492kg/ha) in 1969. The report by the United Nations states that fertilizer use in the North had reached 819 thousand tons on the average during the period from 1989 till 1991 (in terms of ingredients). The amount estimated by the United Nations is close to that recently consumed in the South, which is 1 million tons.6) Given the current adverse economic conditions of the North, the amount of fertilizer use estimated by the U.N. seems rather unrealistic.
     The level of chemical fertilizer use in the North was similar to that of the South until the 1980s. During the 1990s, however, the North Korean economy began to stagnate, and the chemical fertilizer consumption in the North has become much less than that in the South. The South estimated that the average consumption of fertilizer (in terms of output) in the North from 1992 till 1994 was 1.437 million tons, 70% of South Korea's level of consumption of 2.4 million tons. However, if converted in terms of ingredients, the North's chemical fertilizer consumption would be far below the level of the South. In other words, the amount of 1.437 million tons would be 400 thousand tons in terms of ingredient, only 40% of South's level of consumption of one million tons (27.7% of the average real weight, based on the fertilizers produced in the North.)
     Since the gross area under cultivation in the North has been estimated to be 1.47 million hectares in 1999; 580,000 of rice, 600,000 of maize, 100,000 of barley and wheat, 100,000 of pulse, 40,000 of potatoes, and 50,000 of miscellaneous cereal grains, it needs at least 400 thousand tons of chemical fertilizer to cultivate those crops (in terms of ingredients). (See Table 2)
     If it converted into urea, fused phosphate, and potassium chloride, produced in the South, in terms of real weight, the North needs a total of 1.12 million tons of those fertilizers to cultivate those crops ; 445 thousand tons of urea, 500 thousand tons of fused phosphate, and 170 thousand tons of potassium chloride. Furthermore, it would take at least an additional 500 thousand tons (1.6 million tons in terms of real weight) if one were to take into account fertilizer for vegetables, fruits, and mulberries.

Supply of Fertilizer

     In 1998, the total supply of fertilizer was 124 thousand tons (in terms of active ingredients); 47 thousand tons from self-produced fertilizer and 77 thousand tons from imports or aid (see table 3). Compared with 193 thousand tons in 1997 and 200 thousand tons in 1996, the fertilizer supply in 1998 was far less.
     In 1998, the International Fund for Agricultural Development (IFAD) provided the North with 57 thousand tons (real weight) in the form of urea and compound fertilizers, which was totally used up in the IFAD project in the North. IFAD used about 35 thousand tons (real weight) of fertilizer for the double-cropping program on 70 thousand hectares, and used the rest of it for more fertile farmlands.7)

     Therefore, in 1998 only 98 thousand tons of chemical fertilizer (in terms of real weight) was supplied to be used for a land area of 1.8 million ha, excluding the area under the IFAD project. Under normal conditions, the amount of 98 thousand tons would be appropriate for 300 thousand ha of farmland. Thus, only 17% of the actual amount of fertilizer needed was supplied for almost all the farmlands.
     Most fertilizer that the North obtained from abroad in 1998 was imported from, or provided by China, except international organization's aid. In 1998 China exported a total of 63,014 tons of fertilizer to the North (worth about 10.9 million dollars; 44,101 tons of nitrogen, 18,811 tons of compound fertilizer, 100 tons of phosphates, and 2 tons of kalium, etc.), 35% of the amount exported in 1997. China provided the North with fertilizer through various trade channels, such as 16,582 tons through general trade, 13,467 tons through border trade, 10,000 tons through the processing trade, and 20,000 tons of nitrogen-based fertilizer through grant-type aid. In comparison, the South supplied the North with 3,300 tons of fertilizer in 1998.
     The North produced 298 thousand tons of ammonium sulfate, 79 thousand tons of super phosphate, and 27 thousand tons of potassium chloride. In addition, it has a plan to import 300 thousand tons of fertilizer: 280 thousand tons of ammonium sulfate, 10 thousand tons of super phosphate, and 5 thousand tons of potassium chloride. Thus, the North is supposed to have a total of 163 thousand tons of fertilizer in terms of ingredients: 133 thousand tons of nitrogen, 16 thousand tons of phosphates, 14 thousand tons of potash, and etc. However, 100 thousand tons of fertilizer (44 thousand tons in terms of active ingredient concentration) which the South provided following the June 3 "inside agreement" was not included. Therefore, if domestic production, commercial import, international aid, and South Korean aid were included in the account, it would total 210 thousand tons of fertilizer (in terms of ingredient concentration). The amount is 50% of the total fertilizer needed for all cultivation and a 67% increase, compared to the 124 thousand tons of fertilizer supplied in 1998.

 

REVIEWING THE POSSIBILITY OF FERTILIZER AID
TO THE NORTH

     In 1998, fertilizer production capability in the South was 4.788 million tons, the supply being 4.09 million tons and the demand, 3.88 million tons. The South, therefore, holds 210 thousand tons of fertilizer in stock (see table 4). Domestic fertilizer production was 3.55 million tons and the amount of import for the production of compound fertilizer was 310 thousand tons of fertilizer (270 thousand tons of urea, 20 thousand tons of fused phosphate, and 20 thousand tons of the others). The total demand for fertilizer was 3.88 million tons (1.82 million tons for agricultural, 220 thousand tons for industrial use, 600 thousand tons for raw materials, and 1.23 million tons for export). Since the demand in 1998 decreased by 400~500 thousand tons compared to that of the previous year, the South utilized only 78% of the domestic fertilizer production capability.

     The fertilizer demand for domestic use as well as for export is expected to be 4.3~4.4 million tons, excluding that earmarked for fertilizer aid to the North. The current level of domestic fertilizer production is 4.588 million tons, which is less than the 4.788 million tons produced in 1998. This shortfall resulted from the closure of the Jinhae Chemical Plant, with a production capacity of 300 thousand tons. In its stead, Dongbu Hannong Chemical Company was established in 1999, but it has a production capacity of only 100 thousand tons.
     This year, if the South fully utilizes domestic fertilizer plants and imports 300 thousand tons of fertilizer needed to produce compound fertilizer, the supply in the South is expected to be 4.89 million tons. Then, the South could hold an extra 500~600 thousand tons of fertilizer in reserve, after deducting 4.3~4.4 million tons for export and domestic use. Furthermore, if the South properly regulates imports for compound fertilizer and exports of domestic fertilizer, it could secure more fertilizer than expected.
     There are several technical issues to be considered when providing fertilizer aid. First, since 65~70% of the demand for agricultural fertilizer is concentrated during the first half of the year, the South must consider the time element in providing fertilizer to the North. Considering the domestic productivity of fertilizer and the demand, the South's provision of 100~150 thousand tons of fertilizer to the North by the end of June is a possibility. Furthermore, even if the provision were to be postponed until the end of this year, an increase in fertilizer aid would not negatively affect the domestic fertilizer market of the South. Secondly, compound fertilizer and urea seem the most appropriate form of aid to the North. The South already has an experience. It exported 5 thousand tons of urea and compound fertilizer to the North between July of 1997 and September of 1998, and received a positive response. Consequently, there seems to be no technical problem with the current project of fertilizer aid to the North at present.

 

THE PROJECTED IMPACT OF FERTILIZER AID

     In order to evaluate the economic efficiency of the fertilizer aid, one should first consider how much fertilizer contributes to the total production of each crops. Since the fertilizer contribution in quantity depends on each crop, soil, and climate, it is very difficult to evaluate it precisely. Thus, the estimation projected in this paper is based on the statistics of international organizations or opinions of experts in domestic agriculture, based on the assumption that the fertilizer aid to the North will be used in normal soil.

     Assuming 100 thousand tons of fertilizer to be provided to the North is consist of compound fertilizer and urea fertilizer. The effect in quantity will be as shown in Table 5. given that 50 thousands tons are to be used for rice and maize cultivation, respectively. It may be possible to produce a total of 2.18 thousand tons of food with 100 thousand tons of fertilizer aid; 88 thousand tons of rice and 1.3 million tons of maize, which could feed 1.3 million North Korean people for a year. Considering WFP's plan to provide the North with 533.5 thousand tons of food this year, one can easily appreciate the tremendous effect that fertilizer aid has.
     Recently, North Korea has been experiencing a serious shortage in chemical fertilizer, one of the most important factors showing food production. North Korea needs 500 thousand tons of chemical fertilizer for a year and needs at least 400 thousand tons of chemical fertilizer to cultivate food crops. In 1998, it produced 47 thousand tons, and the total supply of fertilizer was only 124 thousand tons including 77 thousand tons from imports or aid. Yet, since the fertilizer from aid is limited to designated areas, some cooperative farms don't receive any support. This means that only 17% of the actual amount of fertilizer needed was supplied for almost all the farmlands.
     This year, Hungnam Factory and Namhung Youth Factory began producing chemical fertilizer again. In addition, aid from the international community including South Korea will be also increased. As a result, about 230 thousand tons of fertilizer will be supplied. Therefore, it is expected that the food shortages of North Korea will be lessened owing to this increased fertilizer supply.

 

<notes>

  1. Figures in this paper are in metric measurements.
  2. Chemical fertilizers, even when they are the same brands, contain varying concentrations of major ingredients depending on manufacturing methods. For instance, even though one container of urea or ammonium sulfate weighs 20kg in terms of real weight, urea contains 46% nitrogen which weighs 9.2kg in terms of ingredient, ammonium sulfate contains 20% nitrogen which weighs 4.2kg. Therefore, one container of urea equals more than two containers of ammonium sulfate in terms of efficiency of fertilizer. Consequently, the "active ingredient," as a standard unit, is frequently used to indicate real efficiency of fertilizer. In this paper, the term "active ingredient" is used to compare the real ingredients of fertilizer.
  3. Hungnam Factory, established in Hamhung city, South Hamkyong province in 1927, has produced fertilizer since 1930. It was once ranked second in the world in terms of productivity, producing 480 thousand tons of ammonium sulfate a year. It began producing calcium cyanamide in 1936 and expanded to produce ammonium chloride and ammonium phosphate in 1941. (The Korea Fertilizer Industrial Co., LTD, Korea's fertilizer history of thirty years, 1994.) In 1991, it became the largest plant in the North, through expansion of its ammonia compound plant and its urea plant in 1968. It can produce a total of 1.33 million tons of fertilizer a year; 180 thousand tons of urea, 400 thousand tons of ammonium sulfate, 350 thousand tons of ammonium nitrate lime, 400 thousand tons of super phosphate, etc. (Production and Consumption of the Agricultural Resources in North Korea, by Choi Se-kyun, Korean Rural Economic Institute, 1995)
  4. International organizations have estimated that it would cost 50 million dollars to improve electric facilities.
  5. Similarly, the Ministry of Unification estimated that the amount of fertilizer used in the South was 283kg/ha in 1982 and 281kg/ha in 1984, while that in the North was 240kg/ha in 1982 and 253kg/ha in 1984.
  6. Fertilizer consumption in North Korea, during 1989~1991, was 652 thousand tons of nitrogen, 157 thousand tons of phosphorus, and 10 thousand tons of potash. United Nation, Statistical Yearbook for Asia and the Pacific, 1991, 1993.
  7. The 57 thousand tons of fertilizer provided by IFAD would total 26 thousand tons, if based on concentration of ingredients. The fertilizer provided by IFAD was mainly used for the class I (good) and class II (moderate) paddy and maize land type.
