The summary of this step is that there is good documentation for the installation of STICS and SticsOnR already. SticsOnR & SITCS ON LINUX As noted, the documentation is already good. This is just some notes (mainly to self) about my experience with the installation of STICS and SticsOnR on a Linux (Ubuntu) system. My…

(2024-04-18, sow +0 days, 0 degree-days_base3, 0 mm rain) The clock has started. Sowing was complete on 18 April, with the first seed planted at ca. kl14. 18 April is 11 days later than sowing 2023, which wasn’t particularly early either. That means the potential for the crop is definitely reduced. We usually say 1%…

At the end of the 2023 season, the question was asked whether we could more readily, yet still robustly, measure canopy cover. We knew the answer to this question: multispectral index from drone captured images. We knew drones gave the coverage. We knew that multispectral make comparisons over time and space more robust. We also…

AUTUMN PLOUGH The plough was out late 19 December. Speaking of ploughing, from when the sugar beet field from 2023 was ploughed, we got the feedback that it was an absolute mess after harvest. We knew this would happen given the soil moisture conditions, but it was a cost we decided to pay. The only…

The field was lifted 14 November, with an expected delivery date of 22 November. There was a lot of rain in the forecast for 15 November – ca. 40mm – which was to be followed by a small cold period of -2C for a few hours. The gut said cover the clamp. The rule-of-thumb guides…

Harvest: 2023-11-14. Published: 2023-11-27. Updated 2023-12-21. A big thanks to the team from Björnstorp & Svenstorp who fought traffic and mud to harvest the crop in what is also a crazy busy time for them. It was approximately 6.5 hours of harvest, at 1.05 ha/hour. Timing As seems to always be the case, there were…

At first glance, by comparing the blockMeshDict files from the OpenFOAM.org User Guide, the blockMesh utility may have seen some changes. For the “Stress analysis of a plate with a hole” example, the mergePatchPairs command has disappeared from the dictionary. For the “Breaking of a dam” example, defaultPatch command has appeared. However, looking at the…

2023-09-03 Probably not the last time I’ll say that (- you learn from your mistakes – ) in the context of Ädelholm, but definitely the first time I’ve heard my daughter say it. Wise beyond her 7 years. The specific mistake was that one of the bolters I had pulled earlier in the season seemed…

By my calculations, 2023 is a “normal” to “safer than normal” year with resepect to bolting risk. This, coupled with the general late sowing, means there shouldn’t be any general issues with bolting in 2023. Ädelholm had a sowing date of 7 April. Taking the station nearest – Alnarp – the approximate vernalisation hours are…

2023-08-08, sow +122 days, 1404 degree-days_base3, 267.4 mm rainfall. RAIN 78 mm in the last two days. I’m guessing that there is no soil moisture deficit anymore. WEEDS Found this nasty thing, thanks to a post on NBRs Facebook. Velvet leaf (Lindmalva) is something there is concern about in the industry, and thus the NBR…
