There is a growing interest and enthusiasm in the production of soybean among farmers in selected states in Nigeria as new yield-enhancing and soil fertility-improving technologies are being introduced to them through an integrated farmer education campaign. Continue reading
Land degradation is the result of a number of largely human-induced factors, such as poor soil and water management practices, deforestation, overgrazing, improper crop rotation and unsustainable land use. In turn, these can significantly affect soil fertility, resulting in diminished crop yields and food insecurity. Traditional methods of modelling and monitoring soil erosion usually require a large number of parameters and many years of taking measurements. However, over the past decade, nuclear technologies and isotopic techniques have been introduced, which can effectively assess the soil and water status of an area, as well as identifying hot spots of land degradation. But how does it work?
