In this study, poultry manure compost and organic fertilizer were added to soils derived from basalt, granite, and river alluvial deposits for use as soil parent materials. Following incubation periods of 30 or 60 days at 25 °C, the physical and chemical properties and adsorption characteristics of the soils were studied. The results indicated that the application of poultry manure compost or o...

Microbes are the key components of the soil environment, playing important roles during soil development. Soil parent material provides the foundation elements that comprise the basic nutritional environment for the development of microbial community. After 30 years artificial maturation of cultivation, the soil developments of three different parental materials were evaluated and bacterial com...

abstract accumulation of heavy metals in soils has become a serious environmental problem in many parts of the world. no information is currently available on the distribution pattern of heavy metals concentration in soils of hamadan province. the objective of this research was to determine the spatial distribution of pb and zn and its relationship with land use and parent materials of a select...

The objective of this study was to investigate the physical, chemical, and mineralogical composition of lateritic soils in order to use these soils as potential commercial products for industrial application in the future. Five lateritic soils derived from various parent materials in Taiwan, including andesite, diluvium, shale stone, basalt, and Pleistocene deposit, were collected from the Bt1 ...

As a part of a broader study of the surface formations in maritime Antarctica, a preliminary survey on the content of radionuclides has been carried out in soils of Byers Peninsula, located in the western end of Livingston Island, South Shetland Islands. Data on natural and artificial radionuclides are very scarce in Antarctica and the studied soil samples can be representative of the maritime ...

topography and climate are two important soil forming factors affecting genesis and clay mineralogy of soils. calcareous and gypsiferous soils are widely spread in arid and semiarid parts of iran and palygorskite is a dominant clay mineral in these soils. the objectives of the study were to: (1) determine soil genesis and classification along the climotoposequence and (2) investigate clay miner...
