Estimates, not guarantees

Every calculator on Lawn by Soil produces an estimate from the numbers you enter and the formula shown on its page. Real results depend on measurement accuracy, product strength and conditions we cannot see. Always follow the product label or official rules where they differ from our estimate.

Follow the label

Fertilizers and pesticides, including pre-emergent herbicides, must be applied according to their product labels, which set the legal rates, timing and safety precautions. Some states and localities restrict fertilizer timing or phosphorus use. Our calculators help with arithmetic and timing; they do not replace the label or advice from your state's cooperative extension service.

Independence
