“Cattle manure is good fertilizer. ... His research in 2006 and 2007 in northern and central Illinois showed that the N fertilizer rate for the subsequent corn crop can be reduced by about 13% when half or more of the residue is removed.

What causes reduced yield?
Plant density: One of the major causes of low crop yield is low plant population because number of productive plants per unit area determines crop yields. ...

What is the milk stage of corn?
Milk stage (or commonly referred to as roasting ear) occurs about 20 days after silking as kernels develop a buttery yellow color and are full of milky white fluid. Stress from pollination through milk stage will readily cause kernels close to the ear tip to abort, as energy is prioritized to the base of the ear.
Why are my corn ears so skinny?
The biggest issue has been flooding and excess soil moisture. For processing corn growers, this has meant reduced field yields with smaller ears or no ears in field bottoms and poorly drained areas. For fresh market growers, wet field areas are producing unmarketable, small, or poorly filled ears.
What causes short ears of corn?
lunt Ear Syndrome (BES) in corn, sometimes also referred to as “Beer Can Ear” Syndrome, is a curious oddity that occurs from time to time throughout the corn growing areas of the U.S. The major symptom of BES, unusually short ears, is the consequence of arrested ear development that likely occurs during the ear size ...
