Agricultural scientists study farm crops and animals, and develop ways of improving their quantity and quality. They look for ways to improve crop yield with less labor, control pests and weeds more safely and effectively, and conserve soil and water. They research methods of converting raw agricultural commodities into attractive and healthy food products for consumers. Agricultural science is closely related to biological science, and agricultural scientists use the principles of biology, chemistry, physics, mathematics, and other sciences to solve problems in agriculture. They often work with biological scientists on basic biological research and on applying to agriculture the advances in knowledge brought about by biotechnology.

     Extractions: home 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. 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.

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.

     Extractions: Soil Conservation There is a growing awareness in Canada of the relationship between agricultural production and environmental issues. As stewards of the land, Canadian farmers are aware of their responsibilities to the environment and are taking positive steps to ensure the environmental sustainability of their industry. Canadian farmers are leaders in sustainable agricultural practices. Long before environmental concerns became familiar to the general population, Canadian farmers were developing techniques that benefit Canada's greatest agricultural asset - the soil. Soil structure improves with increased organic matter and decreased erosion. Agricultural practices that are beneficial to the soil and that are widely used in Canada include conservation tillage, residue management, and extended crop rotation through forage and erosion control. Canadian farmers are pioneers in the development of conservation tillage which includes no-till and low-till practices. These practices, rarely seen thirty years ago, were used on 16% and 31% respectively, of Canada's seeded cropland in 1996. Studies have shown that these techniques offer enormous benefits to farmers, including reduced fuel consumption, less soil erosion, reduced soil compaction, increased crop yields and higher organic matter in the soil.

     Extractions: Precision Agriculture One-Step Closer to Widespread Use MADISON, WI - JUNE 4, 2003 - USDA-Agricultural Research Service scientists at the George E. Brown, Jr. Salinity Laboratory, Riverside, California, have developed general guidelines for soil mapping using mobile equipment. This advanced technology is valuable for looking at changes in soil quality over time; including the presence of pollutants such as salts, pesticides, and fertilizers; and for use in precision agriculture to determine areas that are to be managed to maximize yield, minimize environmental impacts, and optimize the use of resources. Soil is a very diverse media, which can vary from one point to the next in its chemical and physical makeup. Many of these soil properties influence crop yield and can cause yield variations within fields. These soil properties also influence how pollutants move through soil and get into the groundwater or runoff into lakes and streams. One useful means of mapping these changes is using mobile equipment to measure several soil properties simultaneously. In order to determine where to take the optimum number of soil samples that will characterize the patterns in soil properties within a field, information is first obtained through the use of a global positioning system (GPS). Using statistical software developed by Scott Lesch of the Salinity Laboratory, maps of soil properties are then created by a geographic information system (GIS). These maps are used to guide management decisions for precision agriculture.

     Extractions: of Science Sponsored by With the population exceeding 6 billion and growing by about 6 million a month, the need to protect agricultural land and to increase food production has become critical. Does sustainable agriculture have the answers? Printer-friendly version of complete topic About 5000 years ago, large cities were flourishing in the flat plains of what is now southern Iraq. The cities were surrounded by thousands of hectares of crop land irrigated from the rivers. Farmers grew barley, wheat, flax, dates, apples, plums and grapes, and herded sheep and goats for meat and milk. This early example of intensive agriculture proved unsustainable. By around 4000 years ago, desert had replace the fields and the cities had been abandoned. History records many such examples of agricultural communities flourishing and then failing, often because farming eroded the soil, exhausted the soil’s nutrients or caused a build-up of salt. There were many fewer mouths to feed in those days; the global population was probably no more than a couple of hundred million. So if agriculture failed in one area, plenty of arable land remained available for development. The world no longer has that luxury. The need to protect agricultural land and to increase food production has become critical. Around the world the concept of sustainable agriculture has been embraced to try to ensure that food supplies will continue to match demand.

     Extractions: Soil and Land Overview The soils of Newfoundland and Labrador are strongly influenced by location , climate and geology. It is the easternmost province of Canada with a land area of approximately 405,720 km The surface geology of the province is characterized by large areas of coarse textured material (glacial till deposits), washed sediments, peat deposits and rock outcrops. The climate of the Island portion of the province reflects its maritime location with cool moist summers, and relatively mild winters. The climate is suitable for a relatively broad range of crops and cropping practices. The Labrador portion has more extremes of climate due to northern and continental influences. Soils surveys and land use studies show that approximately 100,000 hectares (250,000 acres) of mineral soil in the province is considered suitable for commercial scale mechanized farming. Much larger areas are suitable for agricultural commodities less dependant on soil quality, ie: berry crops pastures , confinement livestock operations and Christmas tree farms.
