چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولDominant Tree Species and Soil Type Affect the Fungal Community Structure in a Boreal Peatland Forest.
Boreal peatlands play a crucial role in global carbon cycling, acting as an important carbon reservoir. However, little information is available on how peatland microbial communities are influenced by natural variability or human-induced disturbances. In this study, we have investigated the fungal diversity and community structure of both the organic soil layer and buried wood in boreal forest ...
متن کاملAssessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.
Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...
متن کاملBehavior of Soil Physical and Chemical Properties against Forest landuse Change (Case Study: Khalkhal County, Ardabil Province)
Extended abstract 1- Introduction Changing the forests and pasture landuses to agricultural lands is one of the major global concerns about environmental degradation and climate change. As a result of the rangeland and forest changes into agricultural land and also tillage operations, about 430 million hectares, representing 30% of the world's total plowed land, are annually eroded and leavin...
متن کاملStudy of Physical and Chemical Soil Properties Variations Using Principal Component Analysis Method in the Forest, North of Iran
The field study was conducted in one district of Educational-Experimental forest at Tehran University (Kheirood-Kenar forest) in the North of Iran. Eighty-five soil profiles were dug in the site of study and several chemical and physical soil properties were considered. These factors included: soil pH, soil texture, bulk density, organic carbon, total nitrogen, extractable phosphorus and depth ...
