In spite of its failures, MARNDR has also had some notable successes: for example, thanks to its fertilizer subsidy policy, the total production of Haiti’s staple cereal crop, maize (corn), increased by more than 70% from 2008 to 2011 [72, 84]. However, nationally, the actual yield ...
In addition, metabolic responses to nutrient releases may result in the outwelling of carbon from coastal wetlands to the open water of the Great Lakes, providing an important subsidy (Bouchard, 2007, Cooper et al., submitted for publication), especially as some lakes undergo dreissenid mussel-...

Three alternative measures are studied to reduce ...
These nutrient supply and dietary pattern trends coincide with specific socio-economic, policy, political, and climatic events from the 1970s to the early-mid 2000s, such as population growth, maize subsidy and crop diversification policies, regime change and drought. This study shows how policy,...
When farmers are faced with cash constraints and if there are differences in the availability and price of a single fertilizer due to differential subsidy levels, they tend to buy and use mostly N fertilizers [10]. If N fertilizer is applied alone, P becomes a yield-limiting element after a...
