Geographic information systems, or GiS, are extensively used in agriculture, especially in precision farming.Land is mapped digitally, and pertinent geodetic data such as topography and contours are combined with other statistical data for easier analysis of the soil.
The Decision Support System for Agrotechnology Transfer (DSSAT) is a set of computer programs for simulating agricultural crop growth. [1] It has been used in over 100 countries by agronomists for evaluating farming methods. [2] [3] One application has been assessing the possible impacts on agriculture of climate change and testing adaptation ...
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity.
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
Soil and Water Assessment Tool (SWAT) is a free and open source hydrology model and GIS computer simulation sponsored by the USDA. SWAT is a well known geographic hydrological model in use by many universities and government agencies around the world, and integrates with commercial products like ArcGIS .
Precision agriculture education. The agricultural industry, including teachers, is still in the relatively early stages of precision agriculture technologies. Precision agriculture has led many to believe that industry-related technologies should lead research and education instead of the other way around.
GIS is used to display, analyse and collate soil data and processes, and also identify different types of soils through mapping and web-based software. [40] Soil Science is used in tandem with GIS to identify individual soil properties applicable to agricultural and urban soil management. The Soil Health Card Programme in India utilises soil ...
[1] [2] [3] Typically, such models estimate times that specific growth stages are attained, biomass of crop components (e.g., leaves, stems, roots and harvestable products) as they change over time, and similarly, changes in soil moisture and nutrient status.
