Abstract:
... Nitrogen mismanagement is a serious concern worldwide since farmers usually overuse chemical fertilizers to increase yield, and consequently their income. The oversupply of chemical fertilizers, particularly nitrogen-based fertilizers, has brought about serious environmental problems, among others, deterioration of water quality, global warming impacts, soil acidification, and water eutrophication ...

Subject:
corn; farmers; fertilizer rates; mineral fertilizers; nitrogen; profitability; research planning; surveys; Kenya
Abstract:
... It is widely perceived that African farmers are under-utilizing inorganic fertilizer. However, very little long-term evidence from farmers’ fields, accounting for variations in agro-ecological conditions, has been assembled to back this claim or determine the conditions under which it is true. Using five waves of nationwide household survey data from Kenya covering 13years, we estimate the relativ ...

Abstract:
... Throughout much of Sub-Saharan Africa (SSA), maize production is characterized by low productivity due to the scarce availability and use of external inputs and recurrent droughts exacerbated by climate variability. Within the integrated soil fertility management (ISFM) framework, there is thus a need for optimizing the application of fertilizers and manure to better use the limited nutrient resou ...
