Cross Slot vs 750a super spring special

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 in the top left quadrant a zigzag darker line where we did not spray any Pacifica (a herbicide for killing grassweeds). Alo in the bottom left you can see the remains of some sort of Roman or bronze age settlement.

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 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 750a area is very obviously different to the other two, which are indistinguishable. 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

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. There was a little bit of overlap between the drills here, so the difference is not as apparent as I thought it would be

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

So there we have it. Until next time.

Hare coursing and CTF

Yesterday I finally bit the bullet and did something I’ve wanted to do for a couple of years; I bought a drone. Needless to say, it’s had a busy first 24 hours. I’ve also been playing with a clever website called DroneDeploy. It has an app which sets a flightpath for your drone, taking photos along the way, and then stitching them together into one¬†HUGE image. Like 250 megapixel huge. This morning I thought I would map our field of winter oats, which has suffered some attention from hare coursers all year. Below is a portion of the field – the tramlines are 30m apart for scale. I have adjusted the colours and contrast to make the tracks more visible, you can click on it to enlarge.

coursing

It is fairly obvious that coursers aren’t adopting a CTF strategy just yet. And unfortunately the police don’t have a lot of luck rounding them up. Shame DJI don’t fit machine guns to their drones. Yet.
