The use of organic fertilizers is becoming more widespread, especially since an increasing number of farmers are reorienting to organic farming. However, on the market there is a relatively limited offer of these treatments compared to conventional fertilizers. Studying their efficiency is a domain still at early stages in our country. This study aims to determine the influence of a chelated complex fertilizer of micronutrients (Codamix) and an organic fertilizer based on proteins and seaweed (Ecoaminoalga), on the total nitrogen content of some crops. These foliar treatments were applied to wheat, maize, sunflower and soybean crops and the total nitrogen content of both leaves and seeds was determined. A control lot where no foliar fertilizers were used was also analysed. Both plant and fertilizer samples were analysed with CHNS Elemental Analyzer, after dehydration. Multiple differences were observed between the control group and the lots where foliar treatments were used, as well as correlations between the type of fertilizer and the nitrogen content for certain crops.
