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…

ÄDELHOLM 2023: WEEK 26, INSECTS THEN RAIN

2023-06-27, sow +81 days, 806 degree-days_base3, 42.4 mm rainfall. DEVELOPMENT Canopy cover was measured from a drone flight yesterday (26th June) morning (ca. 7.30 am) as 84%. The BBRO BeetGRO model puts canopy cover at 95% from 950 degree-days and forward. So, maybe we’re not tracking that badly. The drone batteries had “leaked” a lot…

MODEL-IT 2023

MODEL-it The symposium was the 8th International Symposium on Applications of Modelling as an Innovative Technology in the Horticultural Supply Chain. The name says the most of it. The website says the rest of it. The focus is post-harvest and food processing, but it seems to be mainly post-harvest. HIGHLIGHTS OF MODEL-it 2023 Presentations and…

ÄDELHOLM 2023: WEEK 22 INCL. MECHANICAL ROW WEEDING & HOT AIR BALLOONS

2023-05-31, sow +54 days, 424 degree-days_base3, 28.8 mm rainfall. DEVELOPMENT We’ve still not had much rain. There was a very handy 6 mm last Tuesday. Modal development stage is probably BBCH20, if that exists. Unfortunately an accurate canopy cover figure is not possible as the drone mission attempted on 24 May had to be aborted…

ÄDELHOLM 2023: NO RAIN AND TIII

2023-05-16. sow +39 days, 160 degree-days_base3, 19.4mm rainfall. NO RAIN The last rain we had was three weeks ago. There is some forecast for tonight, but it feels pretty uncertain given it will come from storm activity i.e very hit and miss: we got 5 mm in about 15 minutes in Malmö yesterday with a…

ÄDELHOLM 2023: POST-TI & TII PREP

2023-05-02. sow +25 days, 141 degree-days_base3, 19.4mm rainfall. DEVELOPMENT The modal stage of development is probably BBCH11 – first pair of leaves visible but not unfolded. The cold has slowed things down. My plant count came in at 226, 4.52 per meter, 94 167 plants/ ha. BUT… …now that it is very easy to see…

ÄDELHOLM 2023: WEED CONTROL – TI

2023-04-24. sow +17 days, 101 degree-days_base3, 19.0mm rainfall. WEEDS We have weeds. We also have moist soil and a little rain in the forecast. This means the products that require moisture (Centium, Tanaris, Goltix) will be proper effective. Also in the forecast is a fair bit of cloud and cooler weather. This means the products…

ÄDELHOLM 2023: EMERGENCE, WEEDS, INSECTS

2023-04-18. sow +11 days, 56 degree-days_base3, 15mm rainfall. EMERGENCE It is difficult to put a number on it, but it is definitely >0%. The majority of the field is still bare soil, but there are also many areas with rows of visible cotyledons (BBCH09). A few digs found plants in various stages of development. All…

ÄDELHOLM 2023: ESTABLISHMENT

EARLY CHECK (2023-04-14, sow +7 days, 30 degree-days_base3, 15mm rain) Some signs of life. Unfortunately, some of that life is mice. The further “up the hill” (i.e to the west/ towards the trial site) I went, the more life there was. I would guess that the median growth stage was BBCH02-03 (pellet swollen, on the…

ÄDELHOLM 2023: SOWING

SUMMARY: SOIL PREPARATION: The field was ploughed in Autumn 2022, and harrowed twice prior to sowing (5 and 6 April). No autumn 2022 harrowing was done as by the time I realised that this was something that I should ask for, it was way too wet. FERTILISATION: ProBeta (15-3.6-8-+), broadcast 5 April 2023. The actual…
