Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...

Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-3...

This study attempts to examine the relationship between soil bacterial population and physico-chemical properties of in Kaithal Fatehabad district Haryana. Soil pH ranged from 7.7 10.32 selected sites. EC 200 1780 μS/m at 25 °C. Organic carbon 0.10 1.32% present study. Majority samples showed medium status available nitrogen which 0.0005 0.02%. phosphorus is most for plant use values 6 7. Potas...

The aim of the present work has been directed to investigate the physico-chemical status of the soil at Majherdabri area of Jalpaiguri district, West Bengal, India. The soil samples have been collected using conventional method during summer (April) and winter (November). The samples collected from the adjacent forests serve as the control. The pH, organic C, available P, and K are determined b...

Bioremediation uses various microorganisms to detoxify or degrade various harmful substances in the nature, particularly soil and water. In the proposed work, five species of micro-organisms were used to analyse their impact on various physico-chemical parameters of water. In the first attempt the actual physico chemical parameters of the collected sample water were noted down (Fresh sample par...

soil organic matter is an indicator of soil, agriculture and environmental quality, playing important roles in soil strength and sound environmental functions. size and chemical fractionation of soil organic matter are long-standing approaches in clarifying their key role in soil processes. twenty seven surface samples (0-20 cm) and 6 pedons from different landform units were sampled and descri...

some of arid regions problems of iran are saline and sodic soils. in improvement and reclamation of iranian arid rangelands, some foreign species of atriplex had been imported and adapted for many years ago. the most adapted species was atriplex canescens. at the present research, some environmental factors, vegetative characteristics (na, ca, mg and k), soil properties (moisture, ec, ph, solut...
