Where to put a farm weighbridge, why the concrete approaches matter more than the deck, pit versus surface, and a realistic timeline from order to first load.
How axle weigh pads work, why summed axle weights are less accurate than a full bridge, what pads cost, and the jobs they're genuinely good for on a farm.
The realistic options for weighing grain without a weighbridge, from merchant intake weights to heap estimates, with what each costs and when it's fine.
What the Weights and Measures Act means for farm weighbridges, when a bridge must be approved and verified, and why most grain sales don't require it.
What to check before buying a used weighbridge: load cells, deck corrosion, indicator age, moving costs, and when paying extra for new makes sense.
Following the harvest year as it unfolds - crop totals, daily progress, and keeping the team aligned.
Why the harvest spreadsheet cracks in the exact weeks it's needed most, and what a load-by-load system looks like that survives a big wheat day.
A working column layout for a harvest spreadsheet, the habits that keep it accurate through wheat, and an honest look at where it stops coping.
The record-keeping jobs to do in the fortnight before the first field: areas checked, sheds allocated, tares taken, meters tested and the team briefed.
How harvest teams lose track of fields, sheds and varieties, what each role needs to know, and why one shared record beats radios and WhatsApp groups.
The five figures worth checking every harvest evening — tonnes cut, moisture trend, shed space, drier backlog and tomorrow's movements — and why.
What combine yield monitors measure, why they drift 3-5% without calibration, and why the weighbridge stays the ground truth for tonnage and money.
Typical UK harvest dates by crop — winter barley from early July, wheat through August — plus what actually decides the start: moisture, not the calendar.
How to work out how many grain trailers a combine actually needs, where the chain breaks at the pad and the drier, and the fixes that genuinely help.
What to agree with a combining contractor before the machine arrives: whose areas count, whose weights count, and who fills in the paperwork.
Knowing what is in each shed - fill levels, crop mixes, and stock movements after the trailer leaves the pad.
Target moisture levels for combining, selling and storing UK grain, what heat and insects do to wet grain, and how to keep a store safe until it's sold.
Flat stores versus silos for UK grain, what storage costs against paying a co-op, and why most storage problems are really record-keeping problems.
How to prepare a grain store for harvest: the clean-down in the right order, proofing and repairs, bait points before grain arrives, and the records to keep.
Why grain temperature is the earliest warning of trouble in store, the targets to hit by autumn and winter, and how to probe, record and act on a rise.
The insects and mites that infest UK grain stores, where they hide between harvests, why cooling below 15°C is the cheapest control, and how to monitor.
On-floor, batch and continuous-flow grain drying compared: costs, throughput, how to match a system to your tonnage, and the drier-as-bottleneck problem.
What grain drying really costs in the UK: fuel per point removed, the weight the water takes with it, commercial charges, and a worked example per load.
How to work out how much grain fits in a shed: floor area, depth and bulk density, a table for common crops, and why heaped estimates flatter the tonnage.
How to sample grain properly at intake and in store, what buyers test for, and why labelled retained samples per load are what settle disputes months on.
Choosing a grain moisture meter for the farm: capacitance versus resistance types, what £100 to £700 buys, calibration drift, and the errors to avoid.
Why oilseed rape heats faster than cereals in store, the 7.5-8% storage moisture target, twice-weekly first-month checks, and how to keep airflow moving.
Connecting loads back to fields so you can see yields, compare seasons, and spot gaps early.
Typical UK yields for wheat, barley, OSR, oats and beans in t/ha and t/acre, why the farm average hides more than it shows, and how to benchmark your own fields.
UK winter wheat averages around 8 t/ha (3.2 t/acre) in a normal year. What separates 7 from 11 t/ha, why seasons swing it, and how to measure your own.
Why the same fields yield well or badly year after year — water, compaction, pH, rotation and headlands — and which of the causes are actually fixable.
Registered area and cropped area are not the same thing. How margins and tracks shrink the cropped acre, and why yield must divide by what you drilled.
1 hectare is 2.4711 acres, so divide t/ha by 2.4711 for t/acre. A conversion table for common yields, the classic unit mix-ups, and how bushels fit in.
Specific weight is grain density in kg/hl, measured with a chondrometer. Typical minimums for wheat, barley and oats, what lowers it, and how claims work.
How to benchmark yields against national averages, your own field history and other farms — and the honesty rules that stop the comparison flattering you.
The per-field records worth keeping each season, why field knowledge dies in one person's head or a drawer of diaries, and when the payoff arrives.
How to estimate wheat yield before combining with ear counts, grains per ear and TGW — a full worked example, honest error bars, and why it's worth doing.
