Grain Sun-Drying Time Estimator
Estimate the sun-drying days to bring grain down to its safe moisture, given how much moisture you remove per day.
Sun-drying typically removes 1–3 moisture points per good drying day, depending on sun, wind, layer thickness and turning. Spread grain thin on clean tarpaulins, turn every 1–2 hours, and heap and cover it overnight and against rain so it doesn't re-absorb moisture.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Grain Sun-Drying Time Estimator
Sun-drying is the cheapest way to bring grain to safe storage moisture, but you need to plan how many clear days it will take so harvest, threshing and storage line up. This tool estimates the drying days from the moisture you must remove and a realistic per-day removal rate (1–3 points on a good day). It supports the key practices: spread grain thin, turn it often for even drying, and heap-and-cover it overnight and before rain so it doesn't soak moisture back up.

Frequently asked questions
How long does it take to sun-dry grain?+
Roughly (current − target moisture) ÷ the points removed per day. Sun-drying removes about 1–3 moisture points per good day, so dropping wheat from 18% to 12% takes around 2–4 clear days with regular turning.
How can I sun-dry grain faster and evenly?+
Spread it in a thin layer on clean tarpaulins or a drying floor, turn it every 1–2 hours, dry on hot, breezy days, and heap and cover it overnight and against rain. Thin layers and frequent turning are the keys to fast, even drying.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the store/godown and your data never leaves the device.
