Depth distribution of mineralizable nitrogen pools in contrasting soils in a semi-arid climate

Potassium reserves in soils with arid and semi-arid climate in southern Iran: a perspective based on potassium fixation

ABSTRACT- The present research was conducted to study K forms and fixation in soils of southern Iran (Hormozgan Province) with aridic and aridic-ustic regimes and to address the relations between soil mineralogy and potassium forms. Thirteen surface soil samples (0-25 cm) were collected from different regions and analyzed in laboratory. Illite and feldspar and mica are the major clay and soil m...

Soils of Arid and Semi-arid Areas

Conceptual and numerical models of the evolution of pedogenic carbonates in soils of arid and semi-arid regions: A review

Introduction Calcareous soils are widely distributed in arid and semi-arid regions of the world and the presence of carbonates in the soils affects both physicochemical properties and the pedogenic evolution. In addition, soil carbon plays a critical role in the global carbon cycle, and pedogenic carbonates are an important sink for atmospheric carbon. Pedogenic carbonates are also the proxy o...

Glazed Transitional Space as a Passive Heating System (Case Study: Glazed Loggias in Semi-Arid climate)

The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

Impacts of climate change on extreme precipitation events in arid (Bandar Abbas) and semi-arid (Shahrekord) stations in Iran

The aim of this paper is to project extreme precipitation events in an arid and a semiarid station. In order to project climate change based on general circulation models (GCMs), we have applied LARS-WG[1] downscaling tool. This stochastic weather generator down-scaled the climate of two synoptic stations using HADCM3 model and A2 emission scenario for 2040. We extracted extreme precipitation e...
