INFLUENCE OF THE LIGNINIC PRODUCTS ON THE SOIL B1OREMEDIATION

摘要

The present paper reports the influence of the ammonium lignosulphonate (ALS) on the growth of the plants on the arid soils. The quartz sand with 400-800μm granulometry was used as the culture medium , while the been seeds with 98% germination capacity were used as the biological material. The experiments carried out in laboratory showed that ALS has an useful effect on the growth rate of the plant. leading to the increase of the amount of both the green and the dry biomass . The succesive cultures performed on the arid soils treated with ALS evidenced a stimulative effect of the used fertilizer, due to Us assimilation and transformation by the plant. Resides the growth stimulative effect, the ALS can be used with good results for restoration of both the prodnctiv potential of the arid soil and the, bioremediation of polluted areas.
