Abstract
Report about possible soil acidification of SRI advocated biochar as additional organic soil amendment. The aim of this study was to study the effect of rice husk biochar (RHB) on soil properties rice growth and nutrients uptake on a SRI rice field in Jembal Kelantan. However ten ton/ha of RHB was insufficient to alleviate soil pH. Soil salinity significantly decreased 29% with RHB addition and improved vegetative growth stages of rice plant; thus rice yield improved. Besides RHB also provided supplementary C N Ca and increased soil cation exchange capacity (CEC). Therefore biochar induced higher total nutrients uptake in SRI system except K. Moreover the disparity of nutrients uptake were prevalent in tiller than grain; further proving positive effect of RHB enhancing rice plant vegetative growth. Incorporation of biochar in SRI system improved soil properties rice growth and yield. Long-term study is needed to validate the duration of benefits bring upon biochar addition in SRI system.
