About these numbers

Where the math comes from

How is the amount of fertilizer worked out?

Pounds of nitrogen wanted equals your target rate times the area in thousands of square feet. Pounds of product is that divided by the nitrogen fraction on the bag. A 24-0-11 bag is 24 percent nitrogen.

How many cubic yards of mulch do I need?

A cubic yard is 27 cubic feet and covers 324 square feet one inch deep, so area times depth in inches, divided by 324.

How many pieces and pallets of sod do I need?

A standard piece is 16 by 24 inches, which is 2.67 square feet. Pallets vary by farm between about 400 and 500 square feet; this assumes 450, so check with your supplier.

What do these calculators not account for?

They do not know your soil. A fertilizer rate is a starting point and a soil test is what tells you whether nitrogen is what the lawn is short of.
