Acacia Constantinople grows best in mild climates, though it is resistant to high summer temperatures, winter frost, and strong winds. So there is evidence that excessive nitrogen actually causes more carbon to leave the system. The link between soil erosion and other consequences of desertification only confirms this, as erosion is another negative outcome but also a catalyst of previously mentioned problems. And the plant roots will leak out carbon compounds that attract the microorganisms. In contrast, eucalyptus is relatively susceptible to winter frost.

Desertification is a serious form of land degradation that results in the destruction of natural ecosystems and the end of services they provide for us. The locust is considered a tree of dry and warm climates, it grows in coastal areas and is therefore cultivated in Southern Greece and Crete while being considered a relatively frost-resistant plant. Another common problem of the crop cultivation in vulnerable areas is the employment of improper irrigation methods, such as canal irrigation. Copyright HarperCollins Publishers Definition of 'soil' soil (sl ) variable noun Soil is the substance on the surface of the earth in which plants grow. As desertification occurs, this most productive layer of the soil gets blown or washed away from the surface rather quickly because there is no vegetation that would protect it, and nutrients with organic material are lost for good.
