Abstract
Spatial distribution of soil nutrients is not normally considered for smallholder farms in Ghana resulting in blanket fertilizer application which leads to low efficiencies of some applied nutrient...
Highlights
Agriculture is the main economic activity in the Northern region of Ghana
The paper relates to the broader call on research to improve soil fertility and control the continuous soil degradation in Ghana and SubSaharan Africa due to the inappropriate fertilizer application by smallholder farmers resulting in low crop yields which contributes to food insecurity in the region
Geospatial analysis of soil nutrient contents in the study area has proved to be essential in identifying locations in the Northern region of Ghana, where N, P and K levels are relatively low, moderate and high, respectively
Summary
The author’s key research activities are focused on the use of Geographical Information Systems to study the spatial pattern within natural resources. These activities include modelling and mapping underlying spatial features and factors that contribute to the continuous degradation of these natural resources in order to make decisions that could control and monitor the resources. The paper relates to the broader call on research to improve soil fertility and control the continuous soil degradation in Ghana and SubSaharan Africa due to the inappropriate fertilizer application by smallholder farmers resulting in low crop yields which contributes to food insecurity in the region
