Unfortunately spring hasn’t really sprung yet, but hopefully it will soon. Regardless, here is the latest tiller count data from the drill trial. Same old same old.
If you’ve read recent posts here you will know about the drone I’ve bought. It may have had a slight altercation with a tree, putting it out of action for the time being, but before that I made a map of the drill trial field. Here it is, along with some more photos taken the same day, but from a somewhat lower altitude. You can click on any of them to get larger versions.
Here is a large version of the whole field photo. Aside from the different drill areas, which will be explained in the next picture, you can see a zigzag darker line running from half way up the left side to halfway along the top. This is where we did not spray any Pacifica (a herbicide for killing grassweeds). Also in the bottom left you can see the remains of some sort of Roman or bronze age settlement. A stream runs along the bottom, curved, headland and we normally get some flooding, which is what the brown patches are
I tried, and failed, to make some sort of clever interactive overlay of this info on the previous image. The blue section is the Cross Slot area, the red is 750a. Everything else is CO8. The CS and CO8 are indistinguishable, but the 750a area looks distinctly different. From this perspective the crop looks pretty ropey, so I went down to ground level and took the following photos, the locations of which are also marked on this image
1 – CO8. Looks much better from the ground!
2 – Cross Slot. Looks similar to CO8, not surprising given that all the numbers match up too
3 – The Cross Slot / 750a seam. Is it slightly lighter green than the Cross Slot? I wonder if that could be due to the same amount of nitrogen divided amongst a greater number of plants & tillers.
4 – 750a. Slightly less ground visible, but the difference seems much smaller down here compared to from the drone
5 – 750a / CO8 seam. Not a very good comparison because of the coincidental tramline it landed in. Still – not a massive difference though. Again, 750a looks maybe a slightly lighter shade of green
So there we have it. Until next time.
