The Effect of Biochar Application on Nutrient Availability of Soil Planted with MR219

Nur Firdaus Abdul R and Nur Syahirah Abdul R

This study aims to determine the effect of biochars on the soil pH, nutrient content in soil and the growth performance in terms of height of paddy and number of tiller in a field experiment. Biochars as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different types of biomass resulted in variable biochars properties which have an influence on trace elements availability in soil. Both biochars type was tested at equal rates respectively. The results detailing the nutrient content and growth performance of paddy showed that the application of both RH and EFB improve biomass production. The results show that the addition of EFB biochar to soil has a positive effect in growth performance and nutrient content. However, after running the statistical analysis on data, it shows that there is no significant difference between the treatments either in soil pH, nutrient content, plant height and the number of tiller on paddy (P>0.05).
