Knowledge, attitudes, and intentions of biosolids use in agriculture : perspective from the agricultural managers of the Dominican Republic

Abstract

Biosolids have benefits for soil and crop production and contribute to sustainable development. The use of biosolids in agriculture holds great potential for enhancing the economic development of rural communities. This research aims to analyze the mediating role of attitudes between knowledge and the intention to use biosolids as fertilizer. During the examination process 635 questionnaires were obtained, and statistical analysis was performed using SmartPLS. The results of the study indicate that attitudes play a mediating role between knowledge and the intention to use biosolids in agriculture. In conclusion, it is emphasized in the need for positive attitudes towards the use of biosolids among agricultural managers, directors, technicians, and farmers. These results benefit the Dominican Republic's Ministry of Agriculture, agricultural professionals, and farmers. The Ministry can shape policies and offer education on biosolid use. Agricultural leaders should consider attitudes alongside knowledge.
