Soil properties varied significantly in the field experiment
under different fertilization regimes (Tables 1 and 2). The organic
fertilizer (OM treatments) significantly influenced TOC, TN, and pH
in soil, while the influence of OM on the C:N ratio was not
significant (Table 2). Lower pH, and higher TN and TOC were
observed in the OM2 treatment compared with the OM1 treatment
(Table 1).
