Use of Amazonian tree species Inga edulis for soil regeneration and weed control.

Popis výsledku v původním jazyce

Our objective was to evaluate the effects of short-term tree fallow of Inga edulis on weeds and soil fertility. We compared four treatments, namely, (1) natural fallow, (2) planted fallow with I. edulis, (3) planted fallow with I. edulis + herbaceous cover crop kudzu (Pueraria phaseoloides) and (4) continuous cropping of cassava (Manihot esculenta). Tree and weed biomass amount and composition were determined at 3, 6, 9, 13, 17, 20, 24, 28 and 33 months after establishment, while soil samples at 17 and25 months. Improved fallows were able to significantly decrease aboveground weed biomass. Total biomass of improved fallows increased more rapidly than that of natural fallow and cassava cropping. Planted fallows using trees such as I. edulis have the potential to reduce growth of weed species and improve some soil fertility parameters but, on highly degraded soil, a longer time and possibly P fertilisation may be needed to achieve these increases.
