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…

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:…

ÄDELHOLM 2024: PREPARATION – COVER CROP

A decision has finally been made: barley, with hairy vetch sown to some test areas. The vetch might be changed out for crimson clover, if the seed is not available. Seed is sourced from SvenskaFoder. Barley will be sown to ca. 70 kg/ha, and the legume to ca. 30 kg/ha (max permissible = 30% by…
