The study shows the impact of soil treatment with industrial waste on the nutrient content and growth process of green oat plants. The industrial process of carbon dioxide leaching from dolomites produces magnesium carbonate and oxide and calcium carbonate as waste. Both waste types result in the industrial processes of manufacturing magnesium compounds from dolomites as waste product and deposits on the industrial equipment. Besides calcium carbonate the waste contains magnesium carbonate. The difference between the two waste types lies in the double magnesium content, established for the crusts deposits. The research pursues the result of treating soil with industrial waste, managed as four different doses, on soil features like reaction and calcium-, magnesium content as well as on the nutrition process of oat plants, stand out as growth process and calcium- magnesium uptake. The experimental alternatives consists of treating soil with four different waste doses. The results praise that, after soil treatment with several doses of waste, acid soil becomes neutral, while an increase for calcium and magnesium content in soil was also observed. For green oat plants, the growth process by mean of some vegetation characteristics and essential elements uptake was studied. The impact of soil treatment with waste as fertilizer on plant content differs depending on the pursuit nutrient element. The results show that calcium uptake increased by 117% and 72% for magnesium uptake was established. The consequence on the development of green oat plants reveals a positive effect on germination and risen plants, simultaneous with dry matter content decrease. The originality of this paper consists in the revaluation of this industrial waste in agriculture both as a fertilizer and an amendment for acid soils. The importance of this study lies in establishing a new technology that can be used in agriculture by specifying the suitable dose of waste, usage manner and application frequenc
