Ecological agriculture has an important role in preserving soil fertility due to the use of organic fertilizers instead of chemical ones. Organic fertilizers contribute to increasing soil fertility by increasing the content of nutrients; correction of the aerohydric regime in the soil, the intensification of microbiological activity as well as the improvement of the soil structure. The leguminous plants have the ability to ensure their nitrogen requirements through this symbiosis, and after their harvest, an appreciable amount of nitrogen remains in the soil. Within the cultural technologies, soil works represent an important link. In order to correct the aerohydric regime, a scarification was performed and the preparation of the germinal bed was carried out by a passage with a heavy disc. Before sowing, a pass is made with the combinator with the arrow blade (goose paw) with an important role in combating weeds. Vegetable remains are chopped and incorporated into the soil, leading to an increase in the content of organic matter, having an important role in the synthesis of the organic compounds that make up the humus. The degree of weeding is a problem in wheat cultivation in the ecological system, it can lead to high harvest losses of up to 60%. Optimum density, crop rotation, blind seeding, are the main factors to consider in reducing the degree of weeding
