Mild steel coupons (MSCs) buried for thirty months in soils inoculated with bacterial isolate Bacillus cereus-SNB4 resulted in microbiologically influenced corrosion (MIC) based average percent weight loss (APWL) and corrosion rate (CR) as 8.21% and 3.55mgdm d , respectively with 18.86% moisture and 2 1 0.218% organic contents. For nutrient added soils the corresponding figures were -8.95 and -...

The leeward Kohala Field System on the island of Hawai‘i was one of the most intensive pre–European contact dryland agricultural systems. Archaeological and soil analysis has documented changes in soil nutrients over time. Soils were collected under agricultural field walls of different relative ages within the Kohala Field System. These field walls preserved soil from the time of their constru...

Permafrost-affected soils in the Northern latitudes store huge amounts of organic carbon (OC) that is prone to microbial degradation and subsequent release of greenhouse gasses to the atmosphere. In Greenland, the consequences of permafrost thaw have only recently been addressed, and predictions on its impact on the carbon budget are thus still highly uncertain. However, the fate of OC is not o...

Surface humic soils, where fine roots are mainly distributed, can be accidentally buried due to coverage by deposits such as volcanic ash. This soil may influence the vertical distribution of because organic matter strongly affects functions. However, root distributions in soils little understood. In order elucidate effects on distribution, we investigated biomass and characteristics a profile ...

Irrigation practices that are profligate in their use of water have come under closer scrutiny by water managers and the public. Trickle irrigation has the propensity to increase water use efficiency but only if the system is designed to meet the soil and plant conditions. Recently we have provided a software tool, WetUp, to calculate the wetting patterns from trickle irrigation emitters. WetUp...

introduction: minerals are one of the main components of soils which play different roles in the soils. minerals make up about 50% of the volume of most soils. they provide physical support for plants, and create the water- and air-filled pores that make plant growth possible. mineral weathering releases plant nutrients which are retained by other minerals through adsorption, cation exchange, a...

introduction: playa is one of the most important landscapes in arid regions which covers about 1% of the world's total land area. study of playas is important from different points of view especially pedology, sedimentology, mineralogy, environmental geology, groundwater and surface water chemistry. more than 60 playas have been identified in iran. considering the fact that playas and surroundi...

Buried military munitions, such as bombs, artillery projectiles, rockets and landmines can present serious safety hazards. Geophysical investigations are often used to detect such munitions so that they can be safely recovered and destroyed. However, different geophysical methods each have particular capabilities and limitations. Magnetometers and gradiometers are well suited to detecting ferro...
