Soil Health
PubMedThe soybeans in your grocery store's tofu and edamame increasingly come from acidic soils where aluminum poisons roots and fungi rot crops — this research shows that simply planting sorghum nearby, boosted by a trace-mineral spray, could protect those crops without heavy chemical inputs.
Acid soils release aluminum that damages plant roots and makes crops vulnerable to disease-causing fungi. Scientists found that planting soybeans next to sorghum changed the microscopic community in the soil around the roots, producing natural compounds that block aluminum from building up and fight off fungal infections. Adding tiny selenium particles to that combination made the protection even stronger, cutting both aluminum damage and a common rot disease by more than a third.
Key Findings
Soybean-sorghum intercropping combined with selenium nanoparticles reduced aluminum accumulation in soybean roots by 57.4% compared to soybeans grown alone under aluminum stress.
The combined treatment cut Fusarium wilt disease incidence by 34.4%, while intercropping alone reduced it by 10.9%.
Both intercropping treatments reduced oxidative stress markers and enhanced root growth, with the effect linked to measurable shifts in rhizosphere microbiome composition and metabolite signaling.

Growing soybeans alongside sorghum — and adding selenium nanoparticles — dramatically cuts aluminum toxicity and fungal disease in acid soils, with the combined treatment reducing aluminum buildup by 57% and Fusarium wilt by 34% compared to soybeans grown alone.

The soybean, soy bean, or soya bean is a species of legume native to East Asia, widely grown for its edible bean. Soy is a staple crop, the world's most grown legume, and an important animal feed.
