Performance of DNDC model was evaluated using a long term fertilizer experiment (LTFE) datasets at Akola, Maharashtra. The LTFE site represents a semi-arid climate with a mean annual rainfall of 793 mm. Sorghum and wheat crops were cultivated for nine years (1988-1997). The model was parameterized using crop data from black soil region and used to estimate the total organic carbon (TOC) under different nutrient management treatments. It underestimates the total organic carbon in all the treatments in two different ways such as for control (T1) and 50% NPK (T2), it performs less than the measured values in the beginning of the experiment, while for 100% NPK+FYM (T13) and only FYM (T14) treatments the underestimation is found at the end of the experiment. Modelled data analysis using statistical parameters showed 50% NPK treatment was satisfactory. An effort is made to find out the relative performance of three models namely RothC, Century and DNDC using the same LTFE site. By far, RothC model was found to be near to the values of measured TOC as compared to other. Not Available |
