The used of chicken manure rate 1,500 kg (dry weight) gave 43.3 kg N 16 kg P 26.4 kg K 26.2 kg Ca
7.2 kg Mg 7.2 kg S 0.3-0.8 kg Mn 0.3-0.8 kg Cu 0.3-0.8kg Zn per rai (Osodsapa et al., 2008). While
Panitsakpatana (1987) reported that chicken manure gave N=2.7% P2O5=6.3% and K2O=2.0% at 9%
moisture content. Because the soil used in the experiment gave a low micronutrient, plant may absorb it
from chicken manure.
