  2. Soil Moisture Active Passive - Wikipedia

    en.wikipedia.org/wiki/Soil_Moisture_Active_Passive

    The active and passive sensors provide coincident measurements of the surface-emission and backscatter. The instruments sense conditions in the top 5 cm of soil through moderate vegetation cover to yield globally mapped estimates of soil moisture and its freeze-thaw state.

  3. Yield mapping - Wikipedia

    en.wikipedia.org/wiki/Yield_mapping

    Yield mapping or yield monitoring is a technique in agriculture of using GPS data to analyze variables such as crop yield and moisture content in a given field. It was developed in the 1990s and uses a combination of GPS technology and physical sensors, such as speedometers, to track crop yields, grain elevator speed, and combine speed.

  4. Crop yield - Wikipedia

    en.wikipedia.org/wiki/Crop_yield

    In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Cereal yield in tons per hectare and kilograms of nitrogenous fertilizer applied per hectare of cropland.

  5. Crop simulation model - Wikipedia

    en.wikipedia.org/wiki/Crop_simulation_model

    CropSyst, a multi-year multi-crop daily time-step crop simulation model developed by a team at Washington State University's Department of Biological Systems Engineering. [ 4 ] DSSAT , the Decision Support System for Agro-technology Transfer, is a multi-crop, multi-year crop simulation model which evolved from the IBSNAT (1982-1993) and ICASA ...

  6. Grain yield monitor - Wikipedia

    en.wikipedia.org/wiki/Grain_yield_monitor

    The combine grain yield monitor is a device coupled with other sensors to calculate and record the crop yield or grain yield as a modern-day combine harvester operates. Yield monitors are a part of the precision agriculture products available to producers today that provide producers with the tools to reduce costs, increase yields, and increase efficiency.

  7. Sustainable agriculture - Wikipedia

    en.wikipedia.org/wiki/Sustainable_agriculture

    Sustainable agricultural systems are becoming an increasingly important field for AI research and development. By leveraging AI's skills in areas such as resource optimization, crop health monitoring, and yield prediction, farmers might greatly advance toward more environmentally friendly agricultural practices.

  8. Agricultural productivity - Wikipedia

    en.wikipedia.org/wiki/Agricultural_productivity

    Food production per capita since 1961 Grain silos Rice plantation in Thailand Cambodians planting rice, 2004. Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural ...

  9. Sigmoid function - Wikipedia

    en.wikipedia.org/wiki/Sigmoid_function

    The van Genuchten–Gupta model is based on an inverted S-curve and applied to the response of crop yield to soil salinity. Examples of the application of the logistic S-curve to the response of crop yield (wheat) to both the soil salinity and depth to water table in the soil are shown in modeling crop response in agriculture.
