Soils Agroecosystems Forests Aquatic ... home Soil biodiversity Soil biodiversity reflects the variability among living organisms including a myriad of invisible micro-organisms (e.g. bacteria and fungi), micro-fauna (e.g. protazoa and nematodes) meso-fauna (acari and springtails) and the more familiar macro-fauna (e.g.earthworms and termites). Plant roots can also be considered as soil organisms in view of their symbiotic relationships and interactions with other soil components. These diverse organisms interact with one another and with the various plants and animals in the ecosystem forming a complex web of biological activity. Soil organisms contribute a wide range of essential services to the sustainable function of all ecosystems. They act as the primary driving agents of nutrient cycling, regulating the dynamics of soil organic matter, soil carbon sequestration and greenhouse gas emission, modifying soil physical structure and water regimes, enhancing the amount and efficiency of nutrient acquisition by the vegetation and enhancing plant health. These services are not only essential to the functioning of natural ecosystems but constitute an important resource for the sustainable management of agricultural systems. FAO and soil biodiversity A series of activities on soil biological management and soil biodiversity were initiated by FAO in 2000 through the Netherlands-supported programme on agricultural biodiversity. The aims are: firstly, to increase awareness among the range of stakeholders of soil as a living entity and the importance of soil biodiversity for agricultural systems; and secondly, to catalyse the adoption of improved management practices and production systems to enhance soil biodiversity and its biological activity.

Although the information provided here was accurate and current when first created, it is now outdated. The United States has over 330 million acres of agricultural land that produce an abundant supply of low-cost, nutritious food and other products. American agriculture is noted worldwide for its high productivity, quality, and efficiency in delivering goods to the consumer. However, when improperly managed, agricultural activities can affect water quality. The most recent National Water Quality Inventory reports that agricultural nonpoint source (NPS) pollution is the leading source of water quality impacts to surveyed rivers and lakes, the third largest source of impairments to surveyed estuaries, and also a major contributor to ground water contamination and wetlands degradation.

Theodor Friedrich Agricultural Engineering Branch FAO Perspective Shedding light on Conservation Agriculture Everyone who works in tropical agriculture sooner or later starts to wonder whether the way we treat agricultural soils is the right one. Soil conservation has been taught and practised for a long time, yet agricultural soils continue to degrade and erode in the tropics and elsewhere. Conventional tillage, which depletes soil organic matter and creates the conditions for erosion is a major cause. By contrast, ‘conservation agriculture’, which dispenses with pre-plant soil preparation altogether, is gaining ground - literally. What is the major difference between the two concepts of agriculture? For the outsider it might be confusing to draw the line between conventional agriculture (usually employing physical soil conservation works) and conservation agriculture. In fact a number of practices such as conservation tillage, minimum tillage and even zero tillage can be found in both systems. The main difference might be in the mind of the farmer: conventional farmers believe that they do something good and necessary by tilling and would eventually increase tillage if economically possible whereas conservation agriculturists feel uncomfortable whenever they have to force some steel into the soil and would try to avoid it the next time. But is tillage really necessary?

Home Site Map Calendar Search ... Webmaster What is Sustainable Agriculture? Concept Themes Farming and Natural Resources Plant Production Practices Animal Production Practices December 1997 A griculture has changed dramatically, especially since the end of World War II. Food and fiber productivity soared due to new technologies, mechanization, increased chemical use, specialization and government policies that favored maximizing production. These changes allowed fewer farmers with reduced labor demands to produce the majority of the food and fiber in the U.S. Although these changes have had many positive effects and reduced many risks in farming, there have also been significant costs.Prominent among these are topsoil depletion, groundwater contamination, the decline of family farms, continued neglect of the living and working conditions for farm laborers, increasing costs of production, and the disintegration of economic and social conditions in rural communities. A growing movement has emerged during the past two decades to question the role of the agricultural establishment in promoting practices that contribute to these social problems. Today this movement for sustainable agriculture is garnering increasing support and acceptance within mainstream agriculture. Not only does sustainable agriculture address many environmental and social concerns, but it offers innovative and economically viable opportunities for growers, laborers, consumers, policymakers and many others in the entire food system.

We use our soils for doing all sorts of things. Below is a list of some of the activities which we devote the most area to. Agriculture (466 million hectares ABS Australia's economy relies very heavily on its primary resources . Overall Australia produces over $20 billion of agricultural produce every year A successful agricultural industry needs fertile soils with an appropriate soil structure. Some Australian soils have been seriously damaged due to agricultural practices which were not suitable for the particular soil types. Agricultural practices brought into this country by the European colonizers do not work so well in Australia and there is a growing realization that we need to adapt our agriculture to our soils and climate. This is discussed further under the section Most of Australia's soils (420 million hectares ) are in rangelands, under grazing by cattle and sheep. A further 46 million hectares are used for the production of arable crops. Of this land under arable production, 32 million hectares are used to grow wheat.

Future Students Department of Crop and Soil Sciences 2-Year Certificate Undergraduate Graduate Scholarships Courses The Department of Crop and Soil Sciences undergraduate curriculum is designed to train young men and women as professional crop scientists, soil scientists, turfgrass scientists and environmentalists. It prepares them to apply scientific principles of crop and soil management for careers in agriculture, agribusiness, turfgrass management, government agencies, and related areas. Agronomic Sciences Turfgrass Management Turfgrass management encompasses many of the same agronomic principles and applies them to the management of grasses for use on golf courses, athletic fields, home lawns, and recreational areas. Turfgrass adds beauty to the landscape, minimizes sound and air pollution, stabilizes the soil, and reduces the heat load on homes through transpiration cooling. Advanced Study This option is specifically designed for those students that plan to attend graduate school. While all of the options in the department prepare students for graduate study, this option requires the completion of advanced levels of math and the basic sciences such as chemistry, physics, and botany. It also requires the completion of original research and presentation of the results in written form and in an oral or poster format. Environmental Soil Science Many industrial and agricultural practices in Michigan have resulted in degradation of environmental resources. In response to these problems, environmental soil scientists are turning their attention to water pollution, pesticide accumulation in soils, agriculture waste disposal, and environmental remediation.
