This research examined the relationship between beneficial soil fungi and onion plants in different farming systems in the Netherlands. The study found that these fungi readily colonize onion roots in both organic and conventional farms, helping plants access nutrients from the soil. The research has important implications for sustainable agriculture and food production. Impacts on everyday life: – Better understanding of natural plant-fungal partnerships that can help reduce chemical fertilizer use – Insights into sustainable farming practices that maintain soil health – Knowledge that can help improve onion crop yields through natural processes – Support for developing more environmentally-friendly farming methods – Potential for reducing farming costs while maintaining crop productivity
