It relies on the ability of some organisms including plants, fungi and bacteria to reduce the contaminated media and restore their nature. drivers of soil pollution in different land uses; 2) the assessment of negative impacts of soil pollution on food safety, the environment and human health; 3) methods for monitoring, assessing and remediate soil pollution; 4) the existence of national or regional policies and guidelines that include threshold values for different pollutants and endobj (1998). 2. x��VKo7F���۱l��4II�.���Z����z�rJ� ���:�T�к��Z�f��|3���E��' >���l�Ow��R�aN��UMS����~�T�^���ӃǊ���]�㱻�2�~�?�p[}�����5m��R���ލBlB�^mo��� ��+Ӓ3Zv��V��9k�r-� Ņ3�)�:��4/ Q��F��`�;i������U�F˶��FlR �k�a6��%�c�\��� �8OB Productivity declines may be due directly to soil degradation, for example through depletion ofsoil nutrients, soil toxicity, or soil waterholding capacity, or indirectly, for example through infestation ofdegraded soils by persistent weeds that reduce yields. 1060 Vol. On the other hand, the carbohydrate contents showed a slight significant difference between the polluted soils treated with the nutrients. 30 0 obj +uO�ڲ�X����1��?B $��ݯ97L�֒Qm-@����-F����9�������j*.4S.wE9@�9�\��\����x^x���!�p��?#�cVF0`n �%�� Climatic factors: Temperature: indicates how much energy comes to the surface, and towhat extent and for how long physical and chemical processes assist intheformation ofthesoil, and determines to what plants can live in the soil. Polluted soil can harm humans by making contact with the soil or consuming vegetation produce from contaminated soils. These competencies are given as a list of POs. This Day marks the importance of Ozone layer and its role in the environment.

Acton and Gregorich (1995) defined soil quality as “the soil’s fitness to support crop growth without resulting in soil degradation or otherwise harming the environment”. This event commemorates the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. http://www.buzzle.com/articles/how-toprevent-soil-pollution.html control soil (PCS) during 120 days. <> Soil is fundamental to human life on Earth. Key words: soils, soil science, soil degradation, soil pathology, healthy of soil. whereas (NT) gives the highest significant value (14.54 mg/g.dr.wt) In addition to other human practices, the use of chemical fertilizers, pesticides, and fungicides has disrupted the natural processes occurring within the soil resulting in soil pollution. /�n����C�endstream %PDF-1.7 Increased Crop Yield. health, especially because of anthropogenic pollution of soils.
