Impact of Forest, Rangeland and Agriculture Land Uses and Climate on Soil Physical and Chemical Properties in Ilam Province

Fatemeh Karami; Masoud Bazgir

Volume 26, Issue 4 , December 2019, , Pages 953-970

Abstract
  Climate and land use are two important factors which are greatly influence on soil physical and chemical properties. This research was conducted to study the effects of climate and land use on physical and chemical properties of soil in Ilam province in 2016. After initial studies, Ivan area with semi-humid ...  Read More

Soil-plant interaction in salt marsh of Korsia region, Darab, southeastern of Fars province

Mehdi Najafi Ghiri; Alireza Mahmoudi; Shahrokh Askari; Esmaeil Farokhnejad

Volume 25, Issue 1 , April 2018, , Pages 170-182

Abstract
  Halophytes may change different soil properties and nutrients availability by organic materials addition to soil and soil conservation against erosion agents. Destroying these lands and halophytes may have an undesirable effect on environment. To study the effects of physiographic position, plant variety ...  Read More

Relationship between available phosphorus and some soil physical and chemical characteristics in Absard Plain (Damavand Province)

Maryam Dadgar; Masoud Aliha; Enseyeh Faramarzi

Volume 18, Issue 3 , September 2011, , Pages 498-504

Abstract
  Phosphorus is of macro elements for plant growth. Phosphorus compounds are almost insoluble and available phosphorous in soil is rapidly decreased. Use of phosphate fertilizers in soil has been always one of the fundamental issues in agriculture and production due to the low efficiency of phosphorus ...  Read More

Effect of soil antecedent moisture contents on runoff and sedimentation values with simulated rainfall method

Aziz Arsham; Ali mohammad Akhund ali; Abdolkarim Behnia

Volume 16, Issue 4 , January 2010, , Pages 445-455

Abstract
  Antecedent soil moisture is one of runoff and sedimentation crucial factors affected by parameters such as soil properties, topographic-, climatic-, and coverage circumstances etc. The work aimed at determining effects of soil properties and rainfall on runoff and sediment load at various antecedent ...  Read More

Studying the salinization factors in kerman province ( case study: kabootarkhan plain)

Gholam reza Zehtabian; Marzeyeh Tayeb; Mahshid Souri

Volume 13, Issue 4 , February 2007, , Pages 368-384

Abstract
  Salinity is one of the factores affecting the reduction of soil biological potential and vegetation and finally desertification. Water is the most limiting factor for cultivation in arid and semi arid regions.  Due to shortage of surface water resources, the pressure is exerted on under ground water ...  Read More

Growth of Haloxylon spp. plantation, ten years after thinning, in Sabzevar

Mohammad javad Ahmadian yazdi; Esmaeil Rahbar; Orujali Karimi

Volume 14, Issue 3 , January 2007, , Pages 313-322

Abstract
  A general model was developed to explain the interrelationships between soil saturation percentage, mean annual precipitation, and population density on growth and vigority of planted Haloxylon trees. Based on the model, estimated number of population density for 7 years old Haloxylon plantation in Sabzevar ...  Read More
