Recent researches recommend red mud (red sludge) by using in a possible correction of soils with acid reaction and poor content in nutrients. In addition, it was observed that plants of Poaceae family (called generic herbs) show a certain tolerance to this residue. Wheat plants grown in the second year after applying different doses of red mud have shown significantly positive plants trends. Thus, wheat plants grown at a dose of 60 t/ha compared to those of 10 t/ha red mud, formed ears 1 cm longer, had two (2) additional spikes, and the weight of the ear was larger by 0.4 grams. The number of grains in an ear was greater by seven (7), the weight of the grains in the average ear was 0.3 grams more, while the grains were relatively similar in size. The use of red mud in agricultural field conditions was used for the first time on the white luvic soil at the Pitești- Albora resort.
