Using PSNT to reduce corn nitrogen rates

|
By Greg Labarge
| Ohio's Country Journal and Ohio Ag Net Verified
By Greg LaBarge, Ohio State Extension Managing nitrogen (N) efficiently in corn with high N fertilizer prices compared to corn grain prices. In several common production scenarios, soil-supplied nitrogen can replace a significant portion—or in some cases all—of the fertilizer N typically applied. Two situations where this occurs most often are following fall-applied manure and planting corn after nitrogen-rich cropping systems such as alfalfa or long-term cover crops.

Yield responses to potassium fertilizer

| Ohio's Country Journal and Ohio Ag Net Verified
By Greg LaBarge, Ohio State University Extension An analysis of potassium fertilizer response research is giving Ohio farmers clearer guidance on when potassium (K) fertilizer boosts crop yields—and when it does not. The study, conducted by Ohio State University researchers and summarized in a recently released Extension factsheet, draws on 458 field trials across 40 counties to pinpoint crop responses at varying soil potassium levels.

Ohio corn yields climb, but optimal nitrogen rates hold steady

| Ohio's Country Journal and Ohio Ag Net Verified
By Greg LaBarge, Ohio State University Extension While Ohio nitrogen rate recommendations are based on identifying the point on the yield response curve where the yield increase fully covers the cost of the last nitrogen applied, the database of corn response to nitrogen provides an opportunity to evaluate rate changes to maximize yield.
