Korea is one of those countries that have very high usage rates of chemical fertilizers per unit area of cropland. To reduce the fertilizer application rate, a variety of agricultural polices has been introduced since the 1990s. The purpose of this study was conducted to find out the situation of fertilizer use on vegetable crops at 720 farmer’s fields located in 9 province area. Organic fertilizer application rates increased in major field crops. Chemical fertilizer application rates decreased in most of the field crops and vegetables surveyed; however, this reduction was concentrated in phosphate and potassium usage but not in nitrogen. In spite of this decrease, the fertilizer application levels to most crops were maintained at levels much higher than recommended. In the nutrient balance, which was calculated from the difference between input (chemical and organic fertilizers) and output (agricultural products), the nitrogen surplus were higher than recommendation fertilizer application rate. To reduce fertilizer utilization and to conserve environment, further reduction of fertilizer application is essential.
