Recently, animal-waste composts have been extensively used for open culture systems according to area farming practices. This has resulted in the accumulation of specific nutrients and disruption of base balance. We investigated the effects of single basal fertilization and mechanical stimulation on the seedling growth and soil conditions. A low fertilizer application technique was studied for accumulation of excess phosphorus and potassium due to extensive use of animal-waste composts. In conclusion, Thigmomorophogenesis (morphogenesis by mechanical stimulation), which is recommended for the increase of root development on the healthy seedling in young broccoli plants. Phosphate and potassium in the soil after cultivation from the application method in the cell pot system was lower in all soil horizons ranging 0-25cm than that from the standard application rate.
