Remote Sensing Technology for Precision Agriculture

Soil macronutrient sensing for precision agriculture.

Accurate measurements of soil macronutrients (i.e., nitrogen, phosphorus, and potassium) are needed for efficient agricultural production, including site-specific crop management (SSCM), where fertilizer nutrient application rates are adjusted spatially based on local requirements. Rapid, non-destructive quantification of soil properties, including nutrient levels, has been possible with optica...

Hyperspectral remote sensing of agriculture

Remote sensing is being increasingly used in different agricultural applications. Hyperspectral remote sensing in large continuous narrow wavebands provides significant advancement in understanding the subtle changes in biochemical and biophysical attributes of the crop plants and their different physiological processes, which otherwise are indistinct in multispectral remote sensing. This artic...

Remote Sensing of Cropland Agriculture

Web-based Near Real-Time Remote Sensing Data System Providing Decision Support for Precision Agriculture

The U.S. Northern Great Plains is one of the world’s most agriculturally productive areas. Digital Northern Great Plains (DNGP), a web-based remote sensing system available at http://dnpg.umac.org, and Zone Mapping Application for Precision-farming, a decision support tool based on DNGP available at http://zonemap.umac.org, were developed to provide remote sensing imagery and decision support f...

Remote sensing technology for mapping and monitoring vegetation cover (Case study: Semirom-Isfahan, Iran)

To determine the suitable indices for vegetation cover and production assessment based on the remote sensing data, simultaneous digital data with field data belonging to the spring rangeland of the Semirom-Isfahan province were analyzed. During two years of monitoring the annual, grass, forb, and shrub vegetation cover and the total production data from 86 were collected. The Global Positioning...
