Effects of Fermented Fish Residue-Derived Liquid Organic Fertilizer on Soil Chemical Properties, Nutrient Use Efficiency, and Lettuce Growth in Tropical Sandy Soil
Fermented fish residue (FFR) is a byproduct generated from the fermented fish industry and presents a significant opportunity for waste valorization into liquid organic fertilizer (OF). This study aimed to determine the chemical properties of FFR and its derived OF, along with the effects of OF application on soil chem...
