Abstract
This study was conducted to evaluate the effects on soil chemical properties and plant growth after applying sol-dier fly compost (SFC). Treatments were as follows. No fertilizer (NF), control, SFC1 (SFC 250 kg/10a), SFC2 (SFC 500 kg/10a) and SFC3 (SFC 1,000 kg/10a). As compared to control in the pot test, organic matter (OM) and exchangeable sodium (Ex-Na) of SFC3 treatment were increased, and growth and nutrient uptake of young radish were not significantly different. Correlation coefficient between soil chemical factors like total nitrogen (T-N), OM, and CEC and uptake of nitrogen (N) and phosphorus (P) was significantly positive ( p ≤0.05). Compared to control in the field test, electrical conductivity, T-N, OM, Av.-P 2 O 5 , and CEC was increased, and lettuce growth was not significantly different. Correlation coefficient between application amount of SFC and T-N, OM, and Av.-P 2 O 5 was significant positively ( p ≤ 0.05). These results indicated that the application of SFC improved nutrient availability of soil by increasing OM and CEC.
