Abstract

Thirty-day-old tomato seedlings were transplanted on June 17, 2025, and nitrogen, phosphorus, and potassium fertilizer usage was calculated based on soil testing. Based on the calculated fertilizer usage, treatments were administered: water N(20)- P₂O₅(20)-K₂O(20) soluble compound fertilizer alone(WSCF), filtered swine liquid manure(FSLM)+Mono Ammonium Phosphate(MAP), and FSLM+MAP+compost tea. Fertilizer was applied once a week for a total of 13 times. Nitrogen, phosphorus, potassium, calcium, and magnesium contents in tomato plants were high in FSLM+MAP and FSLM+MAP+compost tea treatments compared to WSCF. Soil nutrient content before and after the experiment showed no difference in pH, while organic matter, phosphorus, potassium, calcium, and magnesium contents and soil electrical conductivity decreased. Using FSLM reduced the amount of WSCF used per 10a by 13.66 kg, resulting in a savings of KRW 88,016 in fertilizer costs. Tomato yield per 10a increased by 17.4% in FSLM+MAP treatment compared to WSCF, and by 20.3% in FSLM+MAP+compost tea treatment with statistically significant difference. Gross revenue per 10a increased by KRW 2,822,000 in FSLM+MAP treatment compared to WCSF, and by KRW 3,293,000 in FSLM+MAP+compost tea treatment. Adding the fertilizer cost savings, FSLM+MAP treatment yielded a total profit of KRW 2,910,000 per 10a, and FSLM+MAP+compost tea treatment a total profit of KRW 3,381,016 per 10a.
