The fungal loop model of semiarid ecosystems integrates microtopographic structures and pulse dynamics with key microbial processes. However limited data exist about the composition and structure of fungal communities in these ecosystems. The goal of this study was to characterize diversity and structure of soil fungal communities in a semiarid grassland. The effect of long-term nitrogen fertil...
حوضه آبخیز سدمخزنی شهید پارسا در جنوب شرقی شهرستان فردوس استان خراسان واق گردیده است . بااحداث این سد علاوه برآبیاری اراضی موجود، 700 هکتار از اراضی جدید پایین دست به زیر کشت می روند. عمده ترین معضل موجود در رابطه با حوضه آبخیز، وجود بار رسوب فراوان و تجمع آن در پشت مخزن سد می باشد. لذابه علت عدم وجود اطلاعات کافی از وضعیت فرسایش خاک در حوضه آبخیز، دراین رساله بررسی و مطالعه فرسایش پذیری خاک ان...

objects identification in object-oriented software development - a taxonomy and survey on techniques
analysis and design of object oriented is onemodern paradigms for developing a system. in this paradigm, there are several objects and each object plays some specific roles. identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. this paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. the f...

Parent materials greatly influence soil development and the distribution of soils on the southeastern US Coastal Plain. We examined the physical, chemical, and mineralogical properties of 11 pedons in a 1-ha plot on the Upper Coastal Plain of Georgia, USA. Uniformity of parent materials was assessed by sand grain size characteristics. The soils have sandy epipedons of variable thickness and arg...

the C/N ratio is used to characterize living and dead organic matter. The total C accumulated in biomass is Increasing atmospheric CO2 concentrations, and widespread deposition of N to terrestrial ecosystems has increased the focus on soil generally limited by the availability of N. Forest trees C and N pools. The aim of this study was to estimate the size and are often adapted to N limited con...
