How this works and common questions
About this tool
The page multiplies your area by the seed rate and the fertilizer rate you type. It does not choose a product rate.
How it works
In feet, amount is area times your pounds per 1,000 square feet, divided by 1,000. In metres, amount is area times your kilograms per 100 square metres, divided by 100. Both round up to 2 decimal places.
Rules
The page does not name a rate. You type it. Verify with your local code or a professional. Ballpark estimate, check before you buy or quote.
