Isotopic experiments were conducted to identify the absorption pathways and efficiency of radioactive calcium and phosphorus containing fertilizers on dorsal and ventral leaf surface with different duration on sweet persimmon, tomato, pear, apple and peach. Field experiment was conducted to determine the effective fertilizer application method on tomato. Absorption and translocation of radioactive calcium and phosphorus were analyzed by using bio-imaging analyzer and liquid scintillation counter. In persimmon, tomato, pear, apple and peach according to color intensity from bio-imaging, the nutrient absorption capacity increased with the increase in time and also the colour intensity of fermented mono-calcium phosphate (FMCP) treated dorsal leaf surface was higher than mono-calcium phosphate (MCP). In persimmon, the highest 45Ca radioisotope containing FMCP and MCP absorption of 7.64×10⁴ and 3.68×10⁴ Bq/DWg of leaf were obtained respectively on dorsal leaf surface. Also, the maximum 32P tagged FMCP and MCP with absorption of 8.88×10⁴ and 6.75×10⁴ Bq/DWg of leaf were obtained respectively on dorsal leaf surface. Phosphorus absorption was more than calcium both FMCP and MCP due to higher absorption efficiency of phosphorus from the applied fertilizers. Also phosphorus moved from applied area to other parts of leaf but calcium failed to move from treated area to non-treated area. From this fact, it is indicated that the phosphorus did not seem to enhance the movement of calcium as well as the calcium and phosphorus absorption seemed to be in ionic, soluble or solid state. Dorsal and ventral parts treated tomato experiment showed that FMCP appeared to absorb in greater amount than MCP. Calcium failed to translocate from treated leaf to root of tomato but appreciable amount of phosphorus was found in root of tomato. The translocation of phosphorus and calcium from treated middle leaflet to non-treated leaflet and fruit of tomato were distinctly visualized in the bio-imaging photos by foliar application. The highest phosphorus absorption and translocation of 4.22×10⁴, 0.20×10⁴ and 0.14×10⁴ Bq/DWg were found using FMCP treated, non-treated leaflet and fruit, respectively. The maximum nutrients absorption and translocation were found in dorsal treated leaflet than the ventral treated leaflet of tomato. From either upper or lower leaf treated of tomato experiment, higher absorption was resulted by the bio-imaging and liquid scintillation from dorsal and ventral treated lower leaf than the upper leaf. Also the highest translocation was found when lower leaf surface was used for foliar application. In fertilizer application methods from tomato experiment, the results showed that the soil application of fertilizer was basic practices for increasing the crop yield. On the other hand, foliar application of FMCP helped to improve the fruit quality by the inhibition of blossom end rot of tomato. The highest 45Ca enriched FMCP absorptions of 5.77×10⁴, 7.34×10⁴ and 2.68×10⁴ Bq/DWg on dorsal treated leaf of pear, apple and peach were found, respectively. On the other hand, maximum phosphorus absorptions obtained of 7.45×10⁴, 7.75×10⁴ and 6.99×10⁴ Bq/DWg on dorsal treated leaf were also found of pear, apple and peach, respectively. The absorption rate of foliar applied FMCP and MCP was in the order of apple > pear > peach among the fruit trees. In general conclusion, FMCP appears to be absorbed in greater amount calcium and phosphorus than MCP on sweet persimmons, tomato, pear, apple and peach. Also, the translocation of treated fertilizers was found more effective in dorsal leaf surface and lower leaves than the ventral leaf surface and upper leaves. Aqueous pores as well as stomata could be an important pathways for the uptake of foliar applied fertilizers.
