desertification leads to decrease in the ecosystem c pool and attendant reduction in soil organic carbon (soc). reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

For the first few days after heavy rain or irrigations, water drains from the soil profile until its water content approaches a relatively stable value called the drained upper limit or field capacity. When plants have extracted all of the water available to them, the root zone water content approaches a lower limit of available water, or permanent wilting water content. The water held by the s...

Set-aside farmland can effectively improve the self-rehabilitation of arable soil. Long-term set-asides however cannot satisfy provisionment, therefore the use of short-term set-asides to restore cultivated soil is a better option. Few studies have compared short-term set-aside patterns, and the effects of set-asides on soil microbial community and enzyme enzymes. We analyzed the bacterial stru...

Wildfire is a natural disturbance, though elemental losses and changes that occur during combustion and post-fire erosion can have long-term impacts on soil properties, ecosystem productivity, and watershed condition. Here we evaluate the potential of forest residue-based materials to rehabilitate burned soils. We compare soil nutrient and water availability, and plant recovery after applicatio...

درک الگوی توزیع مکانی ماکروفون خاک بدلیل اثرات آن روی فرآیندهای اکوسیستم بسیار مهم است. لیکن اطلاعات کمی در این خصوص وجود دارد. درمورد تنوع زیستی ارگانیسم ها وجانداران خاکزی که ازاجزای مهم وکلیدی درهرسیستم اکولوژیکی هستند و در بهبود حاصلخیزی خاک و تولیدات زمین وپایداری اکوسیستم ها(ازطریق فرآیندهای بیولوژیک)نقش عمده دارند تحقیقات کمی انجام شده است. این تحقیق جهت بررسی الگوی مکانی پارامترهای تنوع...

The implementation of soil conservation measures is essential to promote sustainable crop production in the Mediterranean region. In an organic rainfed almond orchard located Lanjarón (SE, Spain), a study carried out during 2016–2021 analyzed influence different management strategies (SMSs) (TT, traditional tillage; NT, no VF, cover Vicia faba; VS, sativa; VS-VE, sativa and ervilia) on some sel...

poplar trees are appropriate species for plantation and forest rehabilitation because of fast growing and high wood yield, as well as adaptability to unfavorable climate. salinization of soil and high temperature are the inhibitory factors in khuzestan province. populus euphratica is a tree species that tolerates soil salinity and high temperature. acclimatization of cut seedling of three popul...

Assessment of forest soil and vegetation characteristics provides basic and essential information for the protection and rehabilitation measures in forest ecosystems. Therefore, regard to the importance of this issue, the distribution of different soil properties and vegetation diversity in relation to conservation management and degradation investigated in the oak forests of Ilam province usin...
