DRONES AT NBR: MULTISPECTRAL

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…

ÄDELHOLM 2024: PREPARATION – CULTIVATION

The plough was out late 19 December. It has also been decided that the 8.4 ha field at Ädelholm will host the 2024 version of the NordicSugar + NBR sommarmöte (summer meeting) in early June. Speaking of ploughing, from when the sugar beet field from 2023 was ploughed, we got the feedback that it was…

ÄDELHOLM 2023: STORAGE

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…

ÄDELHOLM 2023: HARVEST

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…

650.01.01.01 SUGAR BEET CLAMP ENVIRONMENT CFD MODEL V2: TRANSLATION TO OpenFOAM11: MESH

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…

ÄDELHOLM 2023: MAN LÄR SIG AV SINA MISSTAG

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…

BOLTERS 2023

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…

ÄDELHOLM 2023: WEEK 31

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…

ÄDELHOLM 2023: WEEK 28, SLOW GOING

2023-07-15, sow +99 days, 1056 degree-days_base3, 107.3 mm rainfall. RAIN We’ve had a good bit now; ca 70mm in the last 20 days. It has included a few heavy downpours, so there are signs of water running across the field, but nothing that will have flown off the farm. DEVELOPMENT It is a little underwhelming.…

ÄDELHOLM 2024: PREPARATION – NUTRIENTS

Phosphorus (P) and Potassium (K) levels are not great at Ädelholm. So, extra will be applied. I assume this will happen in late summer/ autumn, maybe with the cover crop. Phosphorus, 2012 and 2020. Potassium, 2012 and 2020. PRESCRIPTION FILE Using the markkartering.se prescription file creation tool in the “customized” layout, and the following parameters:…
