Agronomic and environmental assessment of a new fertilization strategy using pelleted organo-mineral fertilizers for wheat production in mediterranean agricultural soils.

ABSTRACT: The use of compost in extensive cropping systems is not economically viable due to the high application rates required to meet nutrient requirements. However, compost pelleting increases nutrient concentration while reducing storage, distribution, and application costs. This study evaluated the effects of compost pellets fertilization compared to conventional management on agronomic efficiency and environmental impact in wheat production. Eleven treatments were applied in triplicate to 24 m² plots during the 2022-2023 wheat cycle, combining high phosphorus pellets at sowing (50 kg P ha^-¹) and high-nitrogen pellets at tillering (150 kg N ha^-¹). Fertilizers included (i) organic pellets (OF) enriched with agri-food by-products, (ii) organic-mineral pellets (OMF), and (ii
