Recent high fertilizer prices have prompted huge farmer interest in the possibility of lowering nitrogen (N) rates with commercial microbial supplements that claim to fix N from the atmosphere.

Sulfur (S) deficiency is becoming more common in Indiana crops because, in part, S deposition from coal-fired power plants has been reduced.

Seed corn represents one of the most expensive variable input costs for Indiana corn growers (Langemeier et al., 2021) and so choosing the most economical seeding rate is important for maximizing dollar return to seed at harvest time.
This presentation shares what we know and don’t know about corn response to applied sulfur fertilizer in Indiana, based on field scale research we conducted throughout the state from 2017 – 2021.

The key to maximizing corn yield is largely driven by minimizing the impact of potential yield-limiting factors during the growing season.
With fertilizer being scarce and/or expensive there has never been a better time to fine-tune fertilizer use.

Fertilizer rate decisions have more potential impact on profits when soil test levels of a nutrient are deficient, because yield can be decreased by nutrient deficiency to an extent that offsets the savings of reduced fertilizer rates.

This week marks the first time that corn harvest progress has dropped below the 5-year average for 2021.
This report summarizes corn yield response to fertilizer nitrogen (N) rate in field-scale trials conducted
around the state of Indiana since 2006.
