- Seeding Rate per Acre Calculator
- Convert a target seeding rate into pounds per acre, total seed, bags or units and seed cost, adjusting for seeds per pound, germination and purity.
- Plant Population per Acre Calculator
- Calculate plants per acre from row width and seed spacing, or from field stand counts, with square feet per plant and percent of your target population.
- Row Spacing & In-Row Seed Spacing Calculator
- Work backward from a target plant population to the exact in-row seed spacing, seed drop rate, seeds per 100 feet and seeds per 1/1,000 acre for planter setup.
- Field Acreage & Area Calculator
- Convert field measurements to acres, hectares and square feet for rectangular, triangular, circular and trapezoidal fields, plus perimeter for fencing.
- Growing Degree Days (GDD/GDU) Calculator
