Join us for our next free webinar - Analyzing and Groundtruthing Soil Characteristics

August 23, 2016

Our 2016 webinar series focuses on one ASD spectroscopy application each month.

If you haven't watched each of our previous webinars, visit our webinar recordings page to see what you missed. Some of our past topics include: NIR, Metamorphic Petrology, and Remote Sensing, On-orbit Sensor Absolute Radiometric Calibration for Earth Remote Sensing, and Adventures in Albedo.

This September, our webinar focuses on the application of soil characteristics. 

In this webinar you will learn:

  • How (and why) water alters the spectral reflectance of soil
  • The importance of the location of water in the soil
  • Nutrient and organic matter analysis of soil
  • UAS sensor calibration using an ASD instrument
  • Groundtruthing a UAS sensor using an ASD instrument

Looking to improve your wine grape quality? Join us for a free webinar!

February 12, 2016

On February 17, Dr. Daniel Cozzolino will present NIR Technology in the Wine Industry

Viticulture (from the Latin word for vine) is the science, production, and study of grapes. It deals with the series of events that occur in the vineyard. Join us as we explore the relationship between NIR technology and Viticulture.

In This Webinar You Will Learn

  • How NIR technology can be used for continuous and non-destructive measurements on grape, wine products, and processes over time

  • How NIR analysis can help identify grape characteristics and chemical properties of materials during the production of wine products.

Non-destructive fruit testing

It is becoming quite common to utilize NIR spectroscopy in the field or greenhouse to measure fruit sweetness. This is useful both for deciding when to harvest, but also when running a breeding program. The ability to rapidly and non-destructively select plants with the desired traits allows fruits on those plants to mature and have their seeds collected. A recent study goes beyond sweetness and measures pH - when eaten, the pH of a fruit or vegetable is closely related to the perceived tartness. In the paper listed below, Yahaya et al. developed pH calibrations for mangoes. Others have shown that other fruit properties, such as crispness or firmness in apples, are also quantifiable using near infrared spectroscopy.

FieldSpec spectroradiometer used to monitor drought stress of mandarin orange trees

January 30, 2015

In their paper that was published in the July 2014 issue of Agricultural Water Management, Panigrahia et al. found that it was possible to utilize deficit irrigation of mandarin orange groves while achieving near maximum fruit yield. A level of irrigation that resulted in 50% evapotranspiration (relative to full irrigation) resulted in significant water savings while providing yield that was within 2-4% of the full irrigation yield; fruit quality was a good or better than that achieved with full irrigation.

Landsat 8 Successfully Launches - Is Your FieldSpec 4 Ready?

February 11, 2013

NASA's Landsat Data Continuity Mission (LDCM) launched today from Vandenberg Air Force Base in California. A joint NASA and U.S. Geological Survey (USGS) mission, LDCM will add to the longest continuous data record of Earth's surface as viewed from space. LDCM is the eighth satellite in the Landsat series.

Reflectance Spectroscopy for Soils and Crops Research – See it at the ASD booth at ICPA!

July 09, 2012

Reflectance spectroscopy offers a versatile and precise way to extract important information from soils and crops. ASD’s FieldSpec 4 and HandHeld 2 instruments are valuable tools to researchers in the field of precision agriculture.

Researchers already use this method to assess soil fertility and crop nutrients analysis. They are attracted to the portability, non-destructive measurement, and immediate lab-quality results that our spectroradiometers provide.

Add sophisticated calibration modeling by our SummitCAL experts to create a full crop and soils analysis solution.

Soil applications include total carbon levels and carbonate levels. Crop applications include nitrogen status, soil fertility and water status.

Examples of constituents ASD instrumentation can measure:  
- Moisture
- Total carbon/Inorganic carbon
- Total nitrogen/Mineralized nitrogen
- Clay/Silt/Sand
- Soil organic matter
- Cation-Exchange Capacity (CEC)
- pH

Check out our spectroradiometers and related crops and soils applications at the ICPA Conference in Indianapolis, July 15 – 18. ASD’s booth number is 12.
