PURPOSE: Culture fluid compositions for cultivating a tomato culture medium are provided to maximize the farmhouse income and to prevent environmental contamination by easily controlling the culture fluid concentration. CONSTITUTION: The culture fluid compositions are a standard solution A including 8.5wt.% of nitrogen, 26.0wt.% of K2O, 5.0wt.% of P2O5, 0.15wt.% of B2O3, 4.0wt.% of MgO, 0.2wt.% of Fe, 0.05wt.% of MnO, 0.005wt.% of Zn, 0.001wt.% of Cu, 0.0005wt.% of Mo and 0.05-1.0wt.% of water-soluble coloring agent; and a standard solution B including 11.0wt.% of nitrogen and 22wt.% of CaO. The compositions are diluted to 1/100-1/100 and processed on the underground part or the ground part of tomato plants by using 100-130% concentration for the spring cultivation, 100% concentration for the summer cultivation and 130% concentration for the winter cultivation.
