摘要
Climatic conditions are strongly influencing the development and the existence of soil. The artificial soil is an impetuously necessary improvement brought to the pedological layer of the Earth. The main reason of its existence is the fact that it makes intensive agriculture possible in certain areas where soil formation and the existence of the soil is impossible. Obtaining the artificial soil is done by complex biophysical and chemical ways, using recyclable products, manure and complex chemicals which guarantee the soil life-sustaining property. Thus, it is obtained from recycled cellulose, river gravel, basalt, limestone, animal and plant manure, all together being mixed with mineral salts that contain important chemical elements for plants, such as vanadium, phosphorous and nitrogen. Testing is done by using crops in the laboratory, by putting them under certain conditions and by observing their growth and yield of seed development. The soils chemical properties are constantly measured and corrected, depending on the needs of each plant species separately. This paper has its groundwork in the study of wheat crops that are growing in such soil. The results from these experiments showed that treated with acid rain, the growth of wheat in artificial soils has a higher yield than that obtained for the natural soil, even though it is obvious that the natural soils are better under non-polluted conditions.
