NFLs refer to natural forestlands; GLs refer to grasslands; RDCFs refer to recently developed commercial farmlands; OCFs refer to old commercial farmlands established since 1986; SCLs refer to smallholder cultivated farmland soils. Desc. stat. represents descriptive statistics values, and StD. represents standard deviation. , and indicate that the mean difference is significant at 0.05 and 0.01 levels of significance, respectively.
