Use all information through mapping, soil sampling, Remote Sensing & state of the art technology to better control input costs, increase yield and decrease risk. With our D-GPS systems you'll always be sub-meter accurate. All our vehicles are equipped with D-GPS (Differential GPS) systems. This means that the D-GPS system has sub-meter accuracy. After the field has been mapped, we insert a grid over the field. This means that a soil samples will be taken every hectare. All our samples are individually taken, package and send to a laboratory for analysis.When we receive the laboratory analyses we insert them in a GIS (Geographical Information System) program, where we develop charts of each field. All the red areas are where there is a shortage of chemicals. The third image is an example of a recommendation chart. This chart indicates how much product must be spread on what piece of the field. All the blue areas are where chemicals will be spread. As you can see there is a correlation between the red areas and the blue areas. The reason NDVI is related to vegetation is that healthy vegetation reflects very well in the near infrared part of the spectrum. NDVI provides a crude estimate of vegetation health and a means of monitoring changes in vegetation over time.
