Rice is the major agricultural crop of Korea. If the ground is flat, there will be rice growing. In hilly regions, corn or other vegetables may be grown. Every square inch of land is used for agriculture right up to the mountains and sometimes even fairly steep land is terraced.
Precipitation is seasonally irregular, and in most parts of the country as much as half the annual rainfall occurs in the three summer months. This pattern favours the cultivation of paddy rice in warmer, irrigated regions. Where these conditions are lacking, however, farmers have to stick to the traditional favourite – rice.
Korea’s sparse agricultural resources limit agricultural growth. Climate, terrain, and soil conditions are not particularly favourable for farming. Only about 18% of the total landmass is arable; the major portion of the country is rugged mountain terrain.
