AAA grade 2 formula Green Giant (green bar) in the plantations. 40-50 kilos per Rai rate.Scientific fertilizer or chemical fertilizer, chemical fertilizers should be used: 1 ratio 1: 2, including chemical fertilizer formula 10-10-20, etc. or used as fertilizer, the closest formula fertilizer formula 13-13-21 may typically be put in 100-150 kg per Rai rate per period to grow, but they can use techniques to reduce cost, increase productivity by using pure organic. AAA grade 2 formula Green Giant (green bar), mixed in with Green Giant sow 2 before part 1-part chemical fertilizer can reduce chemical fertilizer costs down. Use of chemical fertilizer will be reduced approximately 30-40 kg per planting cycle.
