Field guides and worked examples

Specific decisions, clear assumptions, and sources you can check.

• Seed Germination Test to Sowing Quantity (Sample Count Formula)

  Turn a small germination test into a sowing quantity using the sample rate, a separate establishment assumption, and the target plant count.

• Two Germination Tests: Decide Before You Sow

  Compare two small germination-test samples from one seed lot, set a decision rule before counting, and keep the single-sample seed quantity visible as a baseline.

• Packet Germination Percent to Seed Quantity

  Turn a printed packet germination percentage into a sowing quantity, then recompute it when the label gives no test date, lot number, or field context.

• Packet Germination vs. Your Own Test: Sizing a Reserve

  When a packet germination figure and your own small test disagree, run both rates through the same seed-demand division and add a labeled reserve instead of averaging them.

• Last Frost Buffer to Transplant Timing

  Use a stated last-frost date and a crop frost-sensitivity buffer to plan a transplant window, with a worked calendar example and explicit assumptions.

• Drip Line Run Time From a Bucket Test

  Turn a chosen watering depth for a raised bed into drip timer minutes using a catch test of real emitter output, with a worked example and stated assumptions.

• Raised Bed Soil Fill Volume: Bags and Cubic Yards

  Convert inside length, width, and fill depth into cubic feet and cubic yards, then round bag or bulk orders with a labeled extra-material allowance.

  2026-10-24
• Compost Top-Dress Volume for a Bed: Depth, Bags, and Cubic Yards

  Convert bed length × width × compost top-dress depth into cubic feet and yards, then bag counts; keep extra-material percent as a separate input.

  2026-10-27
• Mulch Volume for a Bed: Depth, Bags, and Cubic Yards

  Convert bed length × width × mulch depth into cubic feet and yards, then bag counts; keep waste/extra percent as a separate input.

  2026-10-30
• Potting Mix Volume for Round Containers: Diameter, Depth, and Bags

  Convert container diameter and fill depth into cubic inches/feet, then bag counts; keep drainage/headspace as separate inputs—not a product recommendation.

  2026-11-01
• Planting Hole Volume from Root Ball Size: Depth, Diameter, and Backfill Bags

  Convert root-ball diameter and planting-hole depth into cubic feet and bag counts for backfill or amendment; keep hole width multiplier and amendment percent as separate labeled inputs.

  2026-11-03
• Vegetable Row Seed Count: Bed Length ÷ In-Row Spacing

  Convert a measured planting-row length and chosen in-row spacing into seed or transplant counts, with labeled end-guard deductions and a small reserve—separate from germination math.
