Vedclass · Answer

(C) Plant ash is obtained by burning plant tissues at high temperatures (around $600^{\circ}C$).During this combustion process,organic compounds are oxidized.Nitrogen,being a volatile element,is released into the atmosphere in the form of oxides (such as $N_2O$ or $NO_x$) during the heating process.Therefore,nitrogen is not found in the residual plant ash,even though it is an essential nutrient for plant growth.Trace elements,essential elements (excluding nitrogen),and mineral elements remain in the ash as oxides or salts.
