Field notes
The calculator directory divides its 30 tools into ten categories, including feed and forage, water and tanks, storage and grain, and barn and housing. Inputs and outputs are described in practical terms: the fence-post tool accounts for corners, ends, and gates, while feed-cost estimates use daily feed amounts and price per ton. The homepage says results are estimates for planning and names professionals whose advice they do not replace.
