Car tire numbers are explained using the letters and numbers printed on the side of the tire. These numbers tell you the tires purpose, the complete dimensions, the total load/weight capacity, speed rating and more. These specifications are referred to as the tire code.
Organic Soil for Turnips. Clay soil is high in minerals which are good for turnip growth, however, clay is a very dense material and inhibits the growth of tubers. To solve the problem, mix 1 wheelbarrow of sand into a 100 square foot section, and mix it in well. When mixing clay, be sure that the clumps are broken up and mixed with the sand.
Space the trenches 12 to 24 inches apart. Sow purple top turnip seeds about 1 inch apart in the trenches, four to six weeks before the last frost for harvest in late spring, covering the seeds lightly with soil. Purple top and other turnip varieties grow best in daytime temperatures of 60 to 65 degrees Fahrenheit. You must plant them so that you have 45 to 65 days before daytime temperatures reach 75 degrees Fahrenheit.
