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.
A half acre equals to 21,780 square feet. About 43,560 square feet make one acre. To convert acres into square feet, the number of acres is multiplied by the conversion factor. In this case, 0.5 acres is multiplied by 43,560 square feet.
