Jean Martial Johnson

Jean-Martial Johnson’s work contributed to the development of innovation in soil properties and nutrients – including the digital map of Africa at 30 m spatial resolution; RiceAdvice – used by stakeholders addressing plant nutrition challenges in sub-Saharan Africa.

His collection and analysis of rice plant and soil samples in major rice-growing environments – across 20 sub-Saharan Africa countries – resulted in the development of four large datasets consisting of soil fertility properties, macro- and micronutrients in straw and grain, yield gap, and nutrient omission trials.
