How long does it take to map a field?
Roughness of the terrain, sloughs, trees and various other factors all impact the time it takes to map a field. A smooth, square, flat quarter section with no obstacles can be mapped within about an hour but in many cases, it can take up to 2-3 hours.
Why use 10 zones for SWAT MAPS zone maps?
We take pride in high resolution maps so 10 zones are required. This allows enough flexibility to vary rates of product across fields with significant variability. We know some fields with minimal variability may require less than 10 different rates ...
How many soil samples do you take from each field?
All maps have 10 zones, our standard is that we soil sample so as to make 5 soil sample zones. It can vary upon the size of the field, but a quarter section would typically have 5 geo-referenced points per zone, using 2-3 cores per point, or 10-15 ...
Do you use yield maps?
Yield maps, if accurate, can serve as a good report card of what has occurred in your field that year. However, yield maps are different every year and even when using a 10-year average, they don't tell you why the yield was at a certain level in one ...
Does snow affect mapping?
Snow actually causes more challenge for the mapping trucks than for the SWAT BOX. The EC readings are still reliable through snow, and as long as we can drive through the drifts (rather than over them) the elevation data will still be accurate. We ...
Can I use the SWAT BOX on my own equipment to collect EC data?
Yes, if you have access to very accurate elevation data such as LIDAR or RTK using a mobile base station. In some cases, elevation data from your own equipment can be used but the quality of data would first need to be assessed by our map developers.
