Use of reservoir sediments as nutrients for the fertilization
of agricultural soils in the Dominican Republic. The research
project “Use of Reservoir Sediments as Nutrients for the
Fertilization of Agricultural Soils in the Dominican Republic”,
financed by FONDOCyT and in consortium with the
University of Évora, Portugal. It addresses the problem of
erosion in the hydrographic basins and sedimentation in the
Sabana Yegua reservoirs located in the southern region of
the Dominican Republic and Tavera in the northern region.
The purpose of was to determine the nutritional quality of
the sediments stored in the reservoirs, to use it as a soil
improvement amendment in degraded areas of the basin, to
ensure a greater water storage capacity in the reservoirs and
improve its quality, with the purpose to guarantee the
generation of hydroelectricity and supply the irrigation
demand of agricultural producers. The method consisted of
sampling the soils in the hydrographic basins, the sediments
within the reservoirs, as well as in the water and determining
the organic and inorganic elements and heavy metals. The
results showed that the sediments of the reservoirs have a
greater nutritional richness than the soils of the basins. The
water Dominican Republic. The findings confirm the
environmental benefits of using sediments as agricultural
amendments. However, the economic analysis reveals that
the use of these sediments as fertilizer makes it unprofitable
for producers, due to the high costs of extraction, drying,
transportation and application at the parcel level. It is
recommended to carry out other studies in new agroclimatic
zones and with other more profitable crops to evaluate profitability
