(Agric Engineering Project Topics & Materials)

The increase of salinity in soil and water bodies which simultaneously declines the productivity of agriculture is of great concern to the Nigerian Federation which holds agriculture as a major means of survival for its economy. Thus, the proper monitoring,use and management of soil and water bodies is a sure way to proffer solutions to food shortage and poor crop yields. This can however be achieved by the use of a fast, reliable, and accurate in-situ salinometer. A portable in-situ salinometer was constructed and used to measure the conductivity, temperature and salinity of different soil and water samples. The sample resultd were classified into groups viz: low salinity, moderate salinity and high salinity according to standard range of saline soils.
