Total amount of nutrient production according to the number of livestock were 222,331 M/T N,64,716 M/T P₂O₅, and 86,670 M/T K₂O, which are 86.7%,53.6% and 52.7% of the fertilizer requirement, It is estimated that 45 regions showed an overload capacity of fertilizer per hectare in N, 11 regions in P₂O₅ and 13 regions in K₂O. The converted optimum number of livestock was 13,415,000 Livestock Unit (LU).
