Precision Agriculture - NCSU-BAE Agriculture and the farmer have come a long way since the time the first caveman foraged the forest and learned to cultivate plants and animals in an organized manner. Basically, precision agriculture is the control of chemicals, fertilizers, and seeds to achieve the greatest output per acre per amount of input. In its simplest form, precision agriculture would be adding a little extra fertilizer to a few spots in the field that need a little extra or maybe leaving that back corner out that never did produce enough to pay for itself. www.bae.ncsu.edu /programs/extension/agmachine/precision/info.html   (2536 words)

Precision Agriculture In agriculture, precision agriculture is beginning to see widespread application as a management concept in planning, design, making production and environmental assessments, identifying best management practices, and education. Before understanding the principles of using different precision agriculture information, methods and technologies, it is important to understand the implications involved when changing management decisions in the field. Precision agriculture is “a management concept which recognizes variability within the soil and crop environment and maximizes economic production while minimizing environmental impact for a specific location” (Krill, 1994). precisionag.osu.edu /resources/decision.html   (2059 words)

Precision agriculture will become agriculture and it will help us with all those sorts of problems you're talking about. www.abc.net.au /rn/science/buzz/stories/s403123.htm   (1277 words)

New Systems Research Targets Precision Agriculture's Effectiveness This precision farming project instead tries to look at all possible variables that could affect yield—to determine which are most significant. They also measure how precision agriculture affects the amounts of farming inputs needed—such as water, nutrients, and pesticides—and whether the environment benefits from this intensive management. One of the handicaps of precision agriculture to date has been the expense of collecting enough information across a field to apply inputs on a site-specific basis. www.nationalatlas.gov /articles/agriculture/a_precisionAg.html   (1157 words)

Precision Agriculture and GIS Added field level precision opens the way to better manage natural in-field variations where previously, in terms of treatments, a field was normally assumed to be homogenous. Precision farming (PF) and variable rate technologies (VRT) use spatial databases within field environmental and management variables with the aim of evening the application of field inputs while maximizing production across a field. Precision farming relies heavily on the spatial analysis embedded in GIS. www.esri.com /industries/agriculture/business/precision.html   (437 words)

Precision Agriculture: Precision agriculture can be defined as a comprehensive system designed to optimize agricultural production through the application of crop information, advanced technology and management practices.

Last check: 2007-11-05) To illustrate some of the points previously discussed, figure 2 is a time series of both LAI and the ratio of actual to potential ET during the course of a cotton growing season. The first point of interest in figure 2 is the center and lower right-hand portion of the field that had a consistently lower LAI throughout the season. The tendency of the southern portion of the field to have a lower LAI, especially early in the season, may be an indication of nonuniform irrigation applications or variation in soil type. www.uswcl.ars.ag.gov /EPD/remsen/rspreag.htm   (1657 words)

Fort Hays State University Undergraduate agriculture students at Fort Hays State University this past summer began reaping a harvest of satellites and computers as well as grain during wheat harvest on the University Farm. This is precision agriculture, a system of software and machinery designed and built to optimize a farmer's efficiency and profit margin, said Dr. John R. Greathouse, chair of FHSU's Department of Agriculture. For Dr. Bob Stephenson, associate professor of agriculture, who led the harvest team, the advantage to undergraduates is that they will be able to enter the agricultural marketplace and go to work for any of the companies that are developing precision agriculture systems: John Deere, Farmland Industries, Servitech, Crop Quest, Collingwood Grain, Caterpillar and others. www.fhsu.edu /agriculture/farm/hpj3.shtml   (604 words)

Mathematics in ATE: Precision Agriculture Computer tools such as spreadsheets and technology such as Global Positioning Systems (GPS) have begun to transform agriculture to a precision, high-performance industry where data are used to minimize costs and optimize yields.
