Studying the salinity and alkalinity of the soil under different plant coverage
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 8
Abstract
In order to achieve a sustainable management of lands to identify and getting familiar with the physical, chemical and biological performances of the soil in different agricultural, pasture and forest ecosystems, we have embarked on studying the quality of the soil. Of the most important factors affecting plant coverage are the salinity and alkalinity of the soil; however, the mutual impact of plant coverage on these factors and the impact of different cultivations (almond, grape, pea, wheat; poor, average and good pastures) on the pH and the impact of slope were not significant. The impact of different cultivations on the electrical conductivity of the soil with the probability of 99% was significant. The cultivation of almond has the highest electrical conductivity and the cultivations of poor pasture and wheat have the lowest electrical conductivity and this is because of the increasing of the herbal remnants and organic compounds in cultivations such as almond and the decreasing of organic compounds in cultivations such as wheat and poor pasture. Such cultivations don't have a significant impact on the soil's pH due to the tampon attribute of the soil.
