Updated January 2015. The increased cost of health insurance is a central fact in any discussion of health policy and health delivery. As annual premiums edged beyond $16,800 for an average family, costs are blamed for rising uninsured and under-insurance..
Figure 1. Corn growth and temperature levels. Corn will germinate and grow slowly at about 50 F (10 C), but the average first spring planting dates across the U.S. usually begin when the average air temperatures reach 55 F (13 C) and soil temperature at seed depth is favorable for seedling growth.
Planting should not occur before soil temperatures are near 50Â° F for corn and 55Â° F for soybeans with a positive weather outlook. At 50Â° F corn will take approximately 25 days to emerge. At 55-60Â° F corn will take 10-14 days to emerge. At 65-70Â° F corn only takes five to eight days to emerge (Meyer). How long a seed can last in the soil and remain viable depends on temperature, moisture, and pests.
