Work out row spacing plan instantly with clear inputs, formula shown and shareable results.
Rows fit across the field width, so the count is width divided by row spacing rounded down. Headlands at each end for turning machinery shorten each row, and multiplying the usable row length by the row count gives the total linear metres to be sown, sprayed or harvested.
Row count
Rows = floor(field width / row spacing)
Row metres
Total row length = rows x (field length - 2 x headland)
Seed, granular fertiliser, drip tape and in-row spray volumes are all consumed per linear metre of row, so the total row metres is the real basis for ordering.
Run rows across the slope on sloping land to limit erosion, and along the longest dimension on flat land to reduce turning time. Change the width and length inputs to compare both layouts.
