- Description
- Utilization of biochar at high application rates can increase soil C and crop yields, decrease greenhouse gas emissions and reduce nutrient run-off from soils. However, the high application rate of 10 t ha−1 may not return a profit to the farmer due to the high cost of biochar. In this study biochar was modified through pre-treating the biomass and post-treating with phosphoric acid, minerals and different chemical fertilisers to study the effects of two new enhanced biochar fertilisers on the yield and quality of green pepper in a field experiment with 5 fertilisation treatments and 3 replications. The two new biochar fertilisers significantly (P « 0.05) increased the yield of green pepper (11.33–11.47 t ha−1), compared with the conventional chemical fertiliser (9.72 t ha−1). The biochar fertiliser treatments improved the vitamin C content of green pepper from 236.99 to 278.28 mg kg−1, and also significantly (P < 0.05) reduced the nitrate content from 132.32 to 101.92 mg kg−1, compared with chemical fertiliser. This study indicated that, compared to the use of conventional chemical fertiliser, all of the biochar fertiliser treatments could significantly improve the yield and quality of green pepper.
