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…

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…

This seems reasonable, given R&D is an expensive and risky game. Most farmers can neither afford…

OpenFoam version: 9 Solvers: clampPimpleFoam (v5), pimpleFoam Case: clamp_16 IT’S ALIVE I’m not sure if this is the most elegant solution available within the OpenFoam environment, but to swap the inlet and outlet, simply, two different geometries are used. When the air is flowing left-to-right (ltr), the geometry with the inlet on the left is…
