Abstract

Agroecological practices, such as organic fertilisation offer a sustainable approach to crop systems. In this research, organic fertilisers made from a mixture of nejayote (lime-water) and ovine manure were evaluated in maize. Several indexes and indicators were calculated based on field data. The results demonstrated that nejayote-manure fertilisers improve Soil Quality (SQI=14.1), enhance efficiency in nutrient utilisation (Increased Yield, IY= 4.2 Mg ha-1) and promote greater production biomass compared to chemical fertilisation. Organic fertilisations reduced dependency on external inputs and non-renewable energy, increased sustainability in maize, and facilitated the closure of nutrient cycles by integrating livestock, crop and agro-industrial systems.
