Concentration of<20mg P2O5/100gr soil was considered low status, while those with ranges of 20-40 mg P2O5/100 gr soil and >40 mg P2O5/100 gr soil were moderate and high status, respectively. Results showed that of 42 samples analyzed, 19 samples were considered having low P status (1.53-19.54 mg P2O5/100 gr soil) 12 samples having moderate P status (28.20-35.60 mg P2O5/100 gr soil) and 11 samples was high (42.20-674.82 mg P2O5/100 gr soil).
