She also received several awards: PAGASA which was awarded by the President of the Philippines, the Alberto Romualdez Outstanding Health Research Award (National Category), and the Clara Ruth Darby Award (Nutritionist – Dietitians Association of the Philippines).

Dr. Nelly S. Aggangan, Scientist II from the National Institute of Molecular Biology and Technology (BIOTECH) of UPLB has concentrated her research on finding mycorrhizal fungi that help plants thrive in adverse conditions such as thin topsoil, low nutrients, very acidic to slightly acidic pH, and mine tailing and abandoned mined-out areas as an alternative to pricey inorganic chemical fertilizers for reforestation, crop production, improving growth and yield in unproductive agricultural soil, and restoring soil productivity and sustainability. Her research has led to the discovery of 12 species that are now in the MYKOVAM, MYKORICH, and MYKOCAP mycorrhizal inoculants. Furthermore, numerous farmers around the country have attested that these mycorrhizal inoculants may replace 65–85% of the chemical fertilizers needed by plants to achieve normal growth, particularly in infertile soil, and can enhance yields by up to three times depending on the crop. Also, the rehabilitation of a three-decade-old mined-out and abandoned land in Mogpog, Marinduque, is Dr. Aggangan's high-impact initiative. The 3-hectare experimental area is currently covered with green, healthy young mini-forests that can absorb heavy metals from the soil thanks to her leadership and collaboration with the communities and LGUs, creating a cleaner and safer environment. Her outstanding work on mine tailings bioremediation has greatly decreased the effects of environmental (soil, air, and water) degradation and educated the locals.
