Smart inputs for stressed soils: assessment of biofertilizers, nanomaterials, biochar, and biostimulants for sustainable crop productivity in Sub-Saharan Africa

Sub-Saharan Africa (SSA) faces an existential food security crisis driven by severe soil degradation, chronic nutrient deficiency, escalating abiotic stresses, and a rapidly growing population projected to double by 2050. While mineral fertilizer application remains critically low, averaging 9–17 kg/ha compared with a...
