Developing Android/ Interactive Voice Response (IVR) soil nutrient test kits to guide fertilization application around the Keta Lagoon Complex in Ghana.

Project Summary

Lagoons are productive coastal systems providing a wide range of ecosystem services including food supply, nursery habitats, nutrient cycling, etc. Expansion in agricultural activities around coastal lagoons due to population growth has resulted in large export of nutrients into these lagoons. 

This has led to adverse effects such as algal blooms, creation of low oxygen zones and acidification of bottom waters which are harmful to the ecology, fisheries and biodiversity of these lagoons. Keta lagoon, the largest and most productive coastal lagoon in Ghana has in recent times witnessed significant changes in its ecological structure, mainly, due to high influx of nutrients from farms in its watershed.

Parts of the lagoon has been classified by recent studies as having reached a hypertrophic status, thus calling for immediate measures to reduce influx of nutrients into the lagoon. 

This project seeks to reduce the exports of nutrients into the Keta lagoon by; developing easily accessible, cheap and user-friendly Android/IVR soil nutrient testing kits, building farmer capacity in the use of the test kits, and design a routine water quality monitoring program for the lagoon.
