SOIL FERTILITY EVALUATION OF COFFEE (Coffea spp.) PRODUCTION SYSTEMS AND MANAGEMENT RECOMMENDATIONS FOR THE BARAHONA PROVINCE, DOMINICAN REPUBLIC

SOIL FERTILITY EVALUATION OF COFFEE (Coffea spp.) PRODUCTION SYSTEMS AND MANAGEMENT RECOMMENDATIONS FOR THE BARAHONA PROVINCE, DOMINICAN REPUBLIC

Reported yields in most coffee farms of the Barahona province in the Dominican Republic are relatively low (< 290 kg ha-1 parchment coffee). In general, coffee producers do not use diagnostic techniques such as soil testing. This fact prevents them from identifying the limiting factors (especiall...
