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.
Acres are to conceptualize large numbers. there are 27,878,400 square feet in a section. That number is meaningless due to the conceptualization problem. However when you say there 640 acres in a section that number is more easy to grasp. You can not have the square root of acre ie the square root of 40 acres is a meaningless term. 40 acres is 43,560 square feet x 40 = 1.742,400 square ft. take the square root = 1320. Therefore 40 acres is 1320 ft on each side.
