Farm & Ag: fuel, fertilizer, water — and the axle math

Skid tanks, totes and transfer tanks live or die on weight: a tote of UAN is a third heavier than water. Charts for the tanks, weights for the loads, a generator for everything custom.

On the farm everything is heavier than it looks, and weight is what breaks equipment. A 275-gallon tote of UAN 32 fertilizer is over 3,000 pounds — a third more than the same tote of water — and two of them exceed most farm-trailer axle ratings before you’ve loaded anything else. So the workflow here pairs volume with weight: measure or generate a chart for any skid tank, drum or tote, then check what the load actually weighs before you hitch up or stack. The dip chart generator handles the odd custom tanks that fill a yard, and the weight pages carry cited densities for diesel, fertilizer and water.
