“…Little practice of Geophysical methods is done in Nigeria for Agricultural practice specially to observe soil fertility. Some of the available researches include Oladunjoye that used Ground Penetrating Radar (GPR) to characterize valley bottom soil at ilora (Oladunjoye et al, 2021), Yusuf that employed geophysical and geochemical aproaches to investigate ground water quality and soil cultivation viability in mokwa among others. Leti described Agro geophysical methods to identify soil pipes (Leti et al, 2021).…”

One of the keys to national development in developing countries like Nigeria is the diversification of economy. Nigeria’s economy depends majorly on crude oil. The oil sector continue to face challenges like price drop in international market, corruption, reduced quantity of production as forecasted (although new oils are been drilled). These among others makes it necessary for the country to diversify its economy. Agriculture is one of the areas Nigeria have started investing into. New methods are necessary for fast improvement in the sector among which is geophysics. The need for Agricultural Geophysics to be considered for national economic development is discussed. Geophysics as a branch of science that deal with physical processes and phenomena occurring in the earth and its vicinity is applicable to many fields that contribute to the development of the economy of any nation. Such fields include oil, Agriculture, natural resources among others. Geophysical methods applicable in Agriculture like resistivity, electromagnetic induction, and Ground penetrating radar are discussed with their applications in agriculture. The various geophysical methods that are useful in agriculture are reviewed and necessity of their application is also emphasized.

In drylands groundwater is often the only perennial source of freshwater to sustain domestic water supplies and irrigation. Knowledge of the pathways and dynamics of groundwater discharge and recharge is essential to inform sustainable and rational management of limited water resources. The lower valley of the Dallol Maouri in Niger represents a large fossil tributary (i.e. paleochannel) of the River Niger and drains groundwater regionally from the Iullemmeden Basin through coarse-grained Quaternary sediments. The objective of this paper is to quantify groundwater discharge within this paleochannel using piezometry and surface geophysics (TDEM : Time Domain Electromagnetic, MRS : 2 Magnetic Resonance Sounding). TDEM and MRS experiments were conducted at 21 sites along 3 transects show respectively the mean thickness of Quaternary alluvium varies from 11 m to 18 m with the effective porosities ranging from 20% to 33% and hydraulic conductivity of 2 × 10 -3 m/s. Dense piezometric surveys along drainage channel reveal hydraulic gradients of 0.2 ‰ to 0.3 ‰ that indicate Darcy fluxes of 1,000 to 2,000 m 3 /day (dry season, i.e. minimum value). Paleochannel discharge, which currently provides baseflow to the River Niger is the focus local demand to increase access to water for drinking, livestock watering, and irrigation.
