Only modest reductions in moisture mass fraction were observed with delayed harvest
Biomass mass fractions of N, K, and ash usually did not change or decreased with later harvest.
Delayed harvest of napiergrass reduced N removal considerably more than for energycane, potentially recycling some of this N for the subsequent crop.
Occasionally, increases in N, K, or ash mass fractions were observed likely due to changes in biomass composition from leaf drop or free sugar degradation
