The cornfield’s soil must be warmer than 10 °C for seeds to geminate, or sprout new plants. It take from two days to several weeks before a corn seedling pops up above the soil.
Poor soil retards and stunts growth and development. Plants on poor soil do not attain the same favorable growth and development as do similar plants on fertile soil.
Corn grow on infertile soil will not develop sufficiently to produce an ear of grain.
There are a lot of nutrients in the soil which are needed to grow the corn. Phosphorus and nitrogen are nutrients often added to the soil in chemical fertilizers or animal manure. Without them, corn plants take longer to grow, are unhealthy and produce fewer kernels.
In the United States maintaining the high quality agricultural lands requires the constant use of synthetic fertilizers. Corn requires more fertilizer than any other crop, 40% of all nitrogen fertilizer are used on corn.
