摘要: The effects of rice husk biochar (BC) and coal fly ash (FA) on growth yield soil properties were investigated in a lowland soil. All parameters positively influenced by the integrated application BC, FA chemical fertilisers compared with sole fertilisers. Yield increase was 16.4% when BC+FA applied together 50% recommended dose nitrogen (N) N, phosphorus potassium (NPK). Post-harvest analysis suggested that BC both act as supplier, well reservoir nutrients. Accumulation heavy metals plant parts after harvest below toxicity threshold for plants humans. There also no significant change microbial population initial Therefore, combined supplemented could be to improve fertility crop productivity without affecting quality.
