Usually the most difficult part of a crop loss investigation is documenting the severity and quantifying the extensiveness of damage.  AG-RECON offers several tools for this crucial job.


The maps AG-RECON produces show subtle crop trends and defines areas of similarity or change in the field.


AG-RECON's CROP ANALYSIS program looks at a crop using 3 separate maps; MSIRMAP, GROWTHMAP and STRESSMAP.


MSIRMAP demonstrates changes in crop conditions, but colors are enhanced and exaggerated so that subtle changes in crop color or stress can be identified.  Subtle trends in this map provides information on visible symptoms of plant response and clues to contributing factors to damage.


GROWTHMAP shows up to 8 categories of chlorophyll or vegetation density variability and the number of acres for each category condition.  This map is most useful for selecting sites that are representative of a condition for yield sampling, leaf tissue sampling, soil sampling, site observation, or any other quantitative analysis used to characterize a condition.


STRESSMAP identifies changes in surface temperature, with each color change on the map representing a 1F change in temperature. Warmer temperatures indicate relatively more stressed plants. Plant stress can be caused by lack of available moisture or presence of salts, pests, diseases, growth regulators or spray damage.  Use STRESSMAP to identify soil moisture monitoring sites and unusual crop stresses.


Together the 3 maps in AG-RECONís CROP ANALYSIS provide the professional agronomist with an inexpensive, timely, and reliable tool for field investigation, quantification and documentation.


If aerial photography is needed, AG-RECON also offers Black and White, Color, Infrared and Color Infrared aerial photography. Aerial photographs are best used when a traditional photographic format is desired or when the project requires the fine detail of a high resolution photograph.  A photograph is needed when the affected areas are smaller than 5 feet across, like individual row events such as a plugged fertilizer shank, a misadjusted spray nozzle or wheel compaction problems.


Large format and satellite imagery are also available for large scale or regional investigations.
