Abstract
Dennstaedia glauca is used as a green manure in specific agricultural contexts in Puno, Perü. It is applied in conjunction with animal manure and prior to potato cultivation in the first year after a period of fallow. Fronds ofD. glauca, while containing average or low amounts of micronutrients, are high in nitrogen, phosphorus, and potassium in comparison with other fern species and plant material in general. We suggest this fern contributes to fertility of soil used for tuber crops. The plant grows in abundance along watercourses and may play an important role as a recycler of nutrients leached from terraced fields.
