IMPROVE DRAINAGE: Poor drainage often tops the list of yield-limiting factors. Installing tile can have side benefits, including reducing soil compaction.
“The secret to achieving higher corn yields is figuring out why you’re not achieving high corn yields now.” That’s how Bob Nielsen begins his pitch for identifying what might be limiting yields. Nielsen is the Purdue University Extension corn specialist.
“The goal is to identify and figure out how to mitigate yield-limiting factors specific to individual fields,” Nielsen says. “If you fail to identify yield-limiting factors, some agronomic decisions will miss the mark — and either waste money on inputs, leave yield on the table, or both.
