The functions performed by soil biota have Tillage major direct and indirect effects on crop growth and quality, soil and residue-borne pests, diseases Soil ecology incidence, the quality of nutrient cycling and water transfer, and, thus, on the sustainability of crop Agroecosystems management systems. Farmers use tillage, consciously or inadvertently, to manage soil biodiversity. Soil biota Given the importance of soil biota, one of the key challenges in tillage research is understanding and No tillage Plowing predicting the effects of tillage on soil ecology, not only for assessments of the impact of tillage on soil organisms and functions, but also for the design of tillage systems to make the best use of soil biodiversity, particularly for crop protection. In this paper, we first address the complexity of soil ecosystems, the descriptions of which vary between studies, in terms of the size of organisms, the structure of food webs and functions. We then examine the impact of tillage on various groups of soil biota, outlining, through examples, the crucial effects of tillage on population dynamics and species diversity. -
Soil Physics and Agricultural Production
Conference reports Soil physics and agricultural production by K. Reichardt* Agricultural production depends very much on the behaviour of field soils in relation to crop production, physical properties of the soil, and mainly on those and to develop effective management practices that related to the soil's water holding and transmission improve and conserve the quality and quantity of capacities. These properties affect the availability of agricultural lands. Emphasis is being given to field- water to crops and may, therefore, be responsible for measured soil-water properties that characterize the crop yields. The knowledge of the physical properties water economy of a field, as well as to those that bear of soil is essential in defining and/or improving soil on the quality of the soil solution within the profile water management practices to achieve optimal and that water which leaches below the reach of plant productivity for each soil/climatic condition.

The holistic study of soils requires an interdisciplinary approach involving biologists, chemists, ge- ologists, and physicists, amongst others, something that has been true from the earliest days of the field. In more recent years this list has grown to include anthropologists, economists, engineers, medical professionals, military professionals, sociologists, and even artists. This approach has been strengthened and reinforced as cur- rent research continues to use experts trained in both soil science and related fields and by the wide array of issues impacting the world that require an in-depth understanding of soils. -
Fundamentals of Geoenvironmental Engineering
NPTEL – Civil – Geoenvironmental Engineering Module 1 FUNDAMENTALS OF GEOENVIRONMENTAL ENGINEERING A) Scope of geoenvironmental engineering Any project that deals with the interrelationship among environment, ground surface and subsurface (soil, rock and groundwater) falls under the purview of geoenvironmental engineering (Fang and Daniels 2006). The scope is vast and requires the knowledge of different branches of engineering and science put together to solve the multi-disciplinary problems. A geoenvironmental engineer should work in an open domain of knowledge and should be willing to use any concepts of engineering and science to effectively solve the problem at hand. The most challenging aspect is to identify the unconventional nature of the problem, which may have its bearing on multiple factors. For example, an underground pipe leakage may not be due to the faulty construction of the pipe but caused due to the highly corrosive soil surrounding it. The reason for high corrosiveness may be attributed to single or multiple manmade factors, which need to be clearly identified for the holistic solution of the problem. The conventional approach of assessing the material strength of the pipe alone will not solve the problem at hand. A lot of emphasis has been laid for achieving a “green environment”. Despite a lot of effort, it is very difficult to cut off the harmful effects of pollutants disposed off into the geoenvironment. The damage has already been done to the subsurface and ground water resources, which is precious. An effective waste containment system is one of the solutions to this problem. However, such a project has different socio-economic and technical perspectives. -

The future of soil physics Glossary Bibliography Biographical Sketches Summary Soil physics is the study of the solid, liquid, and gaseous phases of soils and of fluxes of fluids and energy in soils. The solid phase consists of mineral and organic matter. The dominantUNESCO liquid in soils is water, and the– dominant EOLSS gases are similar to those in the atmosphere, except that soils contain more CO2 and water vapor and less O2. Interactions between the three phases in soils determine the movement of fluids and energy. Soil physicsSAMPLE established itself as a scientific CHAPTERS discipline in the early 20th century. Much progress has been made since then in the characterization of the physical properties and processes in soils. -

Effect of Environmental Factors on Pore Water Pressure

The results from 2009-2012 were presented and evaluated in a publication by Westerberg et al. (2014) and this report is an extension of that project. In a silt slope the pore water pressures are generally negative, contributing to the stability of the slope. In this report the pore water pressure variations are analyzed using basic statistics and a connection between the pore water pressure variations, the geology and parameters such as temperature, precipitation and soil moisture are discussed. The soils in the slope at Nipuddsvägen consists of sandy silt, silt, clayey silt and silty clay. The main findings were that at 2, 4 and 6 m depth there are significant increases and decreases in the pore water pressure that can be linked with the changing of the seasons, for example there is a significant increase in the spring when the ground frost melts. -
Part 533 – Geotechnical Engineering
Title 210 – National Engineering Manual Part 533 – Geotechnical Engineering Subpart C – Operations 533.20 General A. Soil mechanics is a branch of soil physics and engineering mechanics that describes the behavior of soils and provides the theoretical basis for analysis in geotechnical engineering. Soil mechanics is the application of the laws and principles of mechanics and hydraulics to engineering problems dealing with soil as an engineering material. The testing of soil’s properties are typically done at a testing laboratory with specialized equipment or can be measured or correlated in the field. Soil mechanics is a subdivision of civil engineering and engineering geology that evaluates the action of forces within a soil mass for natural or artificial structures that are supported on or made of soil. B. Collection and analysis of geotechnical engineering data are essential in the investigation and design of engineering structures. The examination and verification of soil properties during construction are critical. Specialized training and experience in geotechnical engineering are needed due to the many factors which depend on interpretation and judgment of soil related issues. Close coordination is needed between the investigation, soil testing, design, and construction functions. C. Soil mechanics testing provides data for evaluating soil and rock as engineering materials for planning, design, and construction. Test results identify the index, chemical, and engineering properties used in the analysis and design of foundations and earth or earth-supported structures such as dams, buildings, bridge foundations, retaining walls, as well as the support structure of buried pipeline systems. 533.21 Data Collection A. The engineering staff or team that prepares the final design will assist in planning of the geotechnical site investigation, sample selection, and final soil testing program. -
