Hydrochar (HC) incorporation affects soil nitrogen (N) transformation, which could further affect the N leaching loss. We conducted a lysimeter experiment to evaluate responses in terms of and rice yield HC applied at low (0.5%) or high (1.5%) rate, while considering three inputs, i.e., 240, 192, 144 kg/ha (named N240, N192, N144, respectively). The results showed that grain was highest (124.3 g/pot) for being significantly reduced minimum achieved study (110.3 N144. Interestingly, input kg/ha, application increased by 6.9–8.0%, equivalent N240. NH4+-N occurred mainly during first 4 weeks season, did not influence both 192 240 kg/ha. However, compared N144 + HC1.5% recorded higher loss 34.6%. This suggests amount increases risk when is low. resulted 10.2–45.3% more NO3−-N inputs were applied, effect significant regard applications involving 20 40% reduction, but this only with treatments 1.5% HC. Moreover, we found organic main form leachate (>80%). More specifically, 7.8–8.3% lower than N192. Based on effects leaching, recommend reduction (N144) (HC 0.5%) ensure crop production protect water environment.
