The fertigation system has continuously been increasing to extend crop cultivation, to provide simultaneously water and mineral nutrients, and to finally enhance yield and quality. The fertigation has a strength to regulate water and fertilizer relatively freely without any limitation of time, quantity, and type of fertilizers. However, a decision for those extremely depends on farmer’s experience due to an absence of standardized fertigation manual for each crop. As a measure to solve these problems, it should be firstly considered when, what and how farmers implement various requirements, and thus we surveyed some basic information to make a concept for crop-customized fertigation manual. The workflow was as followed: 1) choose crops → 9 major vegetables growing with fertigation, 2) monitor massive production area and select 2 sites with different cultivation period, 3) on-site survey and sampling at least two times during cultivation, early harvest and maximum harvest stages, and 4) analyze soil and plant samples and compute optimal rates for crop- and cultivation type-customized fertigation. Plant density was greater in forcing cultivation, and application rates were relatively higher in sequential harvest. The ratio of top dressing (fertigation) to total application generally ranged from 60 - 80% although some farmers were beyond the bounds. Mineral nutrient contents (N, P, and K) were more concentrated in Solanaceae, and it was observed that the quantity and concentration of fertigation were higher in sequential (e.g. cucumber) compared to once (e. g. watermelon). Given the result from the present on-site survey, it is carefully suggested to revise an application rate of top dressing for fertigation, to make the standardized- or customized-fertigation manual by crops, to implement practical means to optimize soil mineral contents, and to extend an education about application of smart and effective fertigation for farmers.
