This may require planting deeper than 1.5 inches under dry soil conditions. If you must plant deeper than 1.5 inches in order to place the seed into uniform moisture, make sure the variety has an excellent emergence score or long hypocotyl. Also, consider seed size when deciding how deep to plant.

November 12, 2011. The American Pregnancy Association states that once sperm is dry it is dead. Sperm cannot be brought back to life by being re-moistened. So if the sperm has dried it is not going to get anyone pregnant. Experts have differing estimates on how long sperm can live outside the man's body. Some report it can be up to five days if the sperm stays within a warm moist environment, such as a woman's cervix. But outside of the human body, sperm have a much shorter existence, from 20 minutes to an hour, depending on such factors as exposure to air and humidity.
