Soil with a pH that's too low can lead to your tomato plant getting too little calcium. To prevent overly acidic conditions, perform a soil test and apply lime at the recommended rate to raise the pH to the 6.0 to 6.5 range. Do this two to four months before you plant.
There are 40 acres in a parcel, which has four sides that measure 1,320 feet each. A square mile is 640 acres, with each side measuring 5,280 feet in length.
One acre equals 0.0015625 square miles, 4,840 square yards, 43,560 square feet or about 4,047 square metres (0.4047 hectares) (see below). While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends on which yard it is based.
