An aerial photo enables potential drainage problems to be diagnosed by locating the wettest areas in a field (shown by the darker areas in the photos). Thanks to the overall view that the photo offers, specialists can better judge the extent of these problems by evaluating the surface area of these wet zones. This first diagnostic is a simple process to provide an idea of the work that needs to be done for each parcel of land.
The first diagnostic is not enough to completely understand the drainage problems that might exist. Observations must be validated in the field. This is what we call “microtopography”, a method that defines and measures the relief of the land.
This technique uses two tools: a fixed GPS-RTK that serves as the base and a mobile GPS-RTK that roams about the field.
Every second, the GPS records the height of the antenna relative to the land surface.
The data from the mobile GPS-RTK is then corrected by the fixed GPS-RTK using post-processing software. This method is precise to within approximately 1cm of elevation and provides exceptional results.

Once the data is collected, a digital model of the land area is produced along with a simulation of surface water movement. This step portrays, with precision, the way in which surface water runs-off but also provides an understanding as to why the water runs-off in a particular manner.
Therefore, this provides a precise representation of the relief of the land as well as the run-off patterns for the water.
Land-leveling is a means of moderating the slope of a field while keeping within the general relief of the field. This helps to favour water run-off and helps to avoid all the drainage problems that can significantly harm yields.
As for the land-leveling plan, it is a method of planning that targets the implementation of complementary improvements for optimum channelling of water run-off. This makes sure that the water runs-off from the field in the right place and in the right way. In addition to benefitting crop yields, these improvements help reduce soil erosion.
Land-leveling represents an interesting added-value for all farmers. And, in some cases, it may be possible to receive a subsidy for this type of work.
Our team is made up of agronomists and engineers who have vital experience in the North-American agricultural sector. Thanks to R&D activities, they have been able to develop this completely innovative service and test the results in order to provide you with the highest quality service.
Thanks to aerial photos, microtopography and yield maps, it is possible to determine the probable causes in yield variations.
In crop production, water is one of the most determining factors for yield.
Most farmers only solve drainage problems in problematic areas. Yet, drainage is a problem that affects the entire field. Only managing specific spots just displaces the problem elsewhere in the field.
As a result, it is essential for all farmers to be 100% sure that their water removal system is adapted to their fields and therefore have in place the best land-leveling plan possible.
