Here is another photo log from a couple years ago. Chickpeas, once introduced as a break crop from a crop rotation dominated by cereals (i.e. wheat and barley) is now just as important and can be just as profitable as wheat and barley. Although chickpea varieties are getting better all the time they are still susceptible to water logging and disease due to too much rain. The variety used in this season was ‘Jimbour’. We have now switched to ‘Hat-Trick’.
The season was set up to be a bumper crop with great crop establishment and moisture profile but then it just kept on raining and we ended up with a lot of plant and not many peas in the pods due to water logging, disease and wind. Enjoy viewing some of the hardships of farming.
The video is me harvesting chickpeas, but not this particular crop.
Recently I’ve been looking at elevation data collected from our Trimble FMX GPS system we use in our tractor.
I imported the logs from this years planting operation. We plant on a swath width of 12m so the data resolution is quite good. The data logs are then transformed into a digital elevation model or DEM and then interpolated to create smoother surface. From the DEM, so far I have developed a contour map and an exaggerated 3 dimensional surface.
You may have noticed from these diagrams that this paddock has quite interesting topography. A couple of places in this paddock water fails to drain freely which can sometimes lead to water logging. My next step is to identify these sinks.
