Combined Application of Biochar and Lime Increases Maize Yield and Accelerates Carbon Loss from an Acidic Soil

Biochar, an ecologically friendly soil amendment, is suggested for large-scale field application its multiple potential benefits, including carbon sequestration, crop yield improvement, and the abatement of greenhouse gas emissions. However, it unknown how effective in changing properties associated improvement when biochar co-applied with lime acidic soil. Here, we examined effects two different biochars, i.e., rice husk (RHB) oil palm empty fruit bunches (EFBB), on nutrient availability, maize, CO2 emission acid Biochars were applied at rates (10 15 t ha?1) combination (100% 75%), while recommended rate NPK fertilizers, 100% lime, without any amendments (control) also included. Hybrid sweet corn was grown pots 20 kg soils 75 days. Plant performance analyses performed before after maize cultivation recorded. Compared to control, combined RHB biochars significantly buffered pH increased availability (e.g., P by 137%), reducing Al Fe concentration harvest. These changes (by 77.59%) uptake compared control. Between relatively more making these than EFBB. this treatment contributed a greater loss as (209% 145% higher EFBB) from We believe that biochar-mediated buffering responsible change. Our results suggest could bring desirable increase performance, although can be short-lived.
