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.
Phosphorus (P) and potassium (K) fertilizer prices have increased dramatically in recent months. If you cannot afford all the fertilizer P and K you think you need or there is not enough fertilizer to be had, you might want to prioritize their use on your farm. The key to prioritizing P and K use is to have recent soil test information for your fields. Top Priority: If soil test levels are below the critical level (Figure 1, Table 1) then crop yield response to added P and/or K might occur. These low testing fields or areas in a field should be given the highest priority for fertilization. The further the soil test is below the critical level the more likely yield will increase with application of that nutrient and that yield increase will likely be larger. The fertilizer application rates recommended for soil tests below the critical level are designed[Read More…]
