Crop Nutrition for Vietnamese Robusta Coffee

Coffee remains one of the most significant sources of income for many farmers in the Central Highlands of Vietnam, but at the same time, yields have been declining or stagnant. Field insights indicate that farmers attempt to counter this trend by experimenting with varying, often increasing amounts of currently available fertilizers. These changes have not worked but have increased production costs markedly. Not to mention that imbalanced fertilizer dressings cause collateral effects of increased contamination of offsite water resources. Robusta coffee systems in the Central Highlands of Vietnam have potential for improvement that can be realized by closing knowledge gaps on balanced crop nutrition, and at the same time, extending access to appropriate nutrients.
